Basic Questions

Q: How do plasma screens work?
Please click here to activate a flash presentation.

Q: Is a plasma screen a TV?

A: Some Plasmavision screens come with a built in tuner, these are denoted by a T as the middle of the three letter block in the model number. Other models will display a TV picture from a tuning device such as a Satellite, Cable or Freeview Set-top Box or an analogue TV tuner. To view the picture you simply need to connect the two devices together using the correct cable.

Q: Are all plasma screens the same?

A: Each manufacturer's plasma screens are different, although they may use some of the same components. For example, many plasma screen companies share the same glass manufacturer. The one component that sets each screen apart is the video processing chipset, which does all the work to convert the video signal into a stunning visual feast. Fujitsu has developed the AVM family of video processors exclusively so that our products provide a superior quality image.

Q: What's the maximum resolution?

A: The maximum physical pixel resolution our screens have is 1366x768 (on 50", 55” and 63” screens). This resolution is known as WXGA (or Wide XGA). You can display computer resolutions up to UXGA (1600x1200) and TV signals up to 1080i (1920X1080), which will be scaled by the Plasmavision to fit the screen. All video signals are scaled to fit the screen.

Q: How much do Plasmavision screens weigh?

A: The screens vary in weight according to their size:
42": 28.5kg
50": 45kg
55”: 55kg
63": 72kg

Q: Can I connect multiple sources to the unit?

A: Yes. Our home theatre monitors accept these kinds of video signals: Composite Video, S-Video, Component Video, analogue RGB (15pin VGA), digital RGB (HDMI with HDCP or DVI-D without HDCP).

Q: What accessories come with the screen?

A: Remote control, user manual, power cable and batteries. All other accessories are sold separately as options due to the nature of different installation applications and uses, but are easily available from your dealer.

Q: What signal formats are supported (for TV, video and DVD)?

A: The Plasmavision screen will display NTSC and SeCAM signals as well as the UK PAL standard. It will also display both interlace and progressive scan signals. Many models, including all the 40 series screens except for the P42VHA40ES, are HD Ready and will also display both the 720p and 1080i high-definition TV and video formats. You can find more information about Plasmavision and High Definition TV here.

Model Differences

Q: What is the difference between the “VHA / HHA / XHA” home theater models and corresponding “VCA / HCA / XCA” business models?

A: Plasmavision model numbers that include H as the second letter in the model number (such as VHA or XHA) are home theatre displays. Similarly model numbers that include T as the second letter in the model number (such as HTS or XTS) are also home theatre models but also include TV tuners. These models accept signals from a wide variety of video sources such as Composite Video, S-Video, Component Video, analogue RGB (15pin VGA), digital RGB (HDMI with HDCP or DVI-D without HDCP).

HCA and XCA models are commercial models, and accept analogue RGB (15pin VGA) signals only. Composite Video, Component and S-Video inputs for commercial models are available on an optional input card sold through your dealer. In 2005, this optional input card also includes stereo audio inputs (x3) and a 10 watt-per-channel stereo amplifier.

Q: What is the difference between the 10 series (eg P42HHA10 - 2003 model), the 30 series (eg. P42HHA30 - 2004 model), and the 40 series (eg. P42HHA40 - 2005 model)?

A: Both the 30 series and the 10 series models share the same AVM processing technology, however the 30 series models have a 10-bit processor versus the 8-bit processor in the 10 version. The difference will be most noticeable when a fast-moving image is on the screen. The faster processor will show a more true image. The 10-bit processor has 1.07 billion colours while the 8-bit processor has 16.77 million colours. The 40 series shares the same 10-bit processor and colour capabilities of the 30 series but includes the added processing features found in the AVM-II video processor.

Q: Why can't my “HCA” business display unit produce a signal via component video?

A: Fujitsu commercial plasma sets accept RGB-analogue signals. “S” and composite video is optional (via an accessory card – see your dealer for details.) Component video signal is not currently available on Fujitsu business display models. If you wish to have component signal, you will need to transfer your component signal input into RGB by using a transcoder.

Installation

Q: What’s the highest altitude you recommend for a plasma display?

A: We suggest installing plasma displays at an altitude no higher than 5,500 – 6,000 ft. At higher altitudes, the lower air pressure (typically below 800hPa) may cause the display to make a buzzing noise. Fujitsu’s warranty does not cover excessive noise in low pressure environments.

Q: Can the Plasmavision set be mounted over a fireplace?

A: Many customers mount their Plasmavision set above the fireplace. As long as the heat travels out into the room (and up the chimney) rather than up over the mantle, the plasma should remain below the internal 104-degree (F) shut-off threshold.

Connectivity

Q: How can I connect things to it?

A: The easiest way to connect other devices is to find out what output connections or cables the device uses and then try to match the connections of the device with those of the Plasmavision. If you find there is a matching problem you may need a converting cable, which will be available from your reseller or most AV and computer specialists.

Q: Can I plug my games console into a plasma screen?

A: Yes. All you need to do to turn a Plasmavision into the ultimate game-playing experience is obtain the console adaptors that enable a composite video, S-video or component video signal to be outputted from the console. The video connector then needs to be married to the respective connection on the plasma display. Your dealer can advise you and provide you with any necessary accessories.

Aspect Ratio

Q: I only get a 4x3 video image when using the DVI connection with my Set-top Box (or DVD player). How can I fill the screen when using the DVI input?

A: The PDS-series models with DVI inputs (introduced in early 2002) can show computer DVI signals (VGA, XGA and so on); however, they cannot show high-resolution DVI TV signals. Source devices outputting these signals first became available in late 2002. Such plasma displays cannot be upgraded in any way to become HDCP compatible.

Q: If I display 4x3 pictures or letterbox pictures, will the black bars burn in?

A: Yes, burn-in will occur if such images are shown for a long time. For normal broadcast TV viewing, use the WIDE or AUTO options of the unit. If you are a cinema purist, you may want to watch feature films in their original aspect ratio (black bars on the sides for 4x3, letterbox bars on top and bottom for extreme widescreen aspect ratios). That’s ok, so long as you revert back to screen-filling WIDE or AUTO modes for most of your viewing.

Q: My Digital TV channels sometimes have black bars straddling the 4x3 picture. My plasma set can’t make them go away. What should I do?

A: Depending on your set top box, it may be able to change the output to fill the screen. Or you can route an additional video cable from the STB to your Plasmavision set’s unused “S-video” input, and select that input, which should allow WIDE modes to stretch the image to fill the screen. Finally, consider watching the same program on a non-DTV channel offered by the same broadcaster.

We expect this problem will go away in time, as more and more shows become available in wide screen, and more and more broadcasters stretch such 4x3 images to fill a wide screen aspect ratio in DTV.


Q: Is it possible to run the screen in a vertical or portrait setting?

A: The screen can be rotated from the landscape position and used vertically. There is a menu function to change the On Screen Display (OSD) to a vertical mode. You can then use a computer graphics card to display in a portrait format (P42GA64 running on an NT-based system). Unfortunately the Plasmavision has no capability in itself to rotate the video or computer signal into portrait mode.

Documentation and Procedures

Q: Are the RS232 codes available for each model?

A:
The download section of this website has full RS232 command codes and explanations for many of Fujitsu Plasmavision displays already on the market. (Link to downloads) If you can’t find the model number you’re looking for, please email us at plasmaservice@fujitsu-general.co.uk to receive these codes. Be sure to include your exact model number.

Q: Can you please send me the IR Codes for my Fujitsu plasma unit?

A: As per company policy we can provide raw hex codes for programming your third-party IR remote’s software. Please email us at plasmaservice@fujitsu-general.co.uk, making sure you specify the Plasmavision model number and include your contact details. We’ll e-mail the codes to you.

Q: Can you please tell me the Fujitsu prefix code to program into my universal remote?

A: We make no prefix codes available for standard all-in-one remote controls. High-end A/V remote controls (e.g. Philips Pronto and others) with Ethernet ports allow you to download specially-prepared codes from end-user-supported websites like www.remotecentral.com, then transfer to the remote via the Ethernet/Cat-5 connection.

Q: How can I get my Plasmavision set serviced?

A: In the first place, please contact the retailer or custom installer that you purchased the screen from. If this isn’t possible or you would like details of other service agents please email us at plasmaservice@fujitsu-general.co.uk

Burn-In

Q: What is “Burn-in”? Do I need to worry about it?

A: Burn-in can happen on any phosphor-based display. Technicians who work on LCD screens say these displays can burn in if abused, too. You’ve probably noticed burn-in on ATM screens, airport flight info monitors, arcade game screens and – at least before we began using cool screen saver backgrounds – computer screens. Severe misuse of your Plasmavision display may cause burn-in. No flat-panel display maker, including Fujitsu General, warrants their displays to withstand burn-in.

Watching standard TV in the NORMAL mode – that is, with black bars straddling the near-square TV picture – can cause burn-in. When wide-screen plasma displays (and rear-projection displays) first came on the market, this kind of burn in was common. Now, since customers have learned how to use Plasmavision display’s WIDE modes to pleasantly stretch TV pictures from one side of the wide screen to the other side.

Q: How can I keep images or lines from burning in on my Plasmavision monitor?

A: Fujitsu’s unique set of features will help you prevent burn-in:
1. Use the WIDE MODES to fill the screen with pictures
2. Set up the Display Power Management Signaling (DPMS) to bleach all the pixels every day, automatically. (refer to the instruction manual)
3. For RGB static images, turn on the Screen Orbiter.
Sometimes plasma sets in lobbies and airports show burned-in logos and numerals. This has also become rare, since today’s screen image software makes it easy to add animation and eye-catching transitions into screen shows.

Design screen slide graphics and presentations so they don’t contribute to burn-in:
Move logos, lines and borders
Avoid saturated primary colors
Avoid white-on-black, white-on-primary, or primary-on-primary schemes
Add motion to slide transitions; for example “uncover,” “push,” and “cover” each moves the image during transition to other images.

Q: What can I do to remove a burn-in image on my plasma?

A: If the burn-in is mild, find the white screen setting in the menu (FEATURES -> OTHERS -> WHITE SCREEN) and activate it. If the burn-in is severe, it may take a long time to go away; or it may be permanent.

Technical Difficulties

Q: My unit shows nothing on the screen and the LED is a red continuous blinking light. What could be the problem?

A: Your installation itself may be causing the problem. Typical causes are overheating and sporadic line voltage drops. Check that the unit is properly ventilated. Consider having an electrician check the voltage, including the voltage with all a/v components, HVAC and other power-consuming devices turned on. If the problem persists an authorized technician may be required to service the unit.

Q: Why are there translucent scrolling horizontal bars on the screen?

A: These bars are commonly known as "hum bars." One cause is that the source and monitor may not share the same electrical ground – instead, they are plugged into separate electric lines grounded on different circuits, or the cable wire itself is not grounded to the same conductor as the unit’s ground. Sometimes battery-powered images sources (camcorders, laptop computers), which share no common electrical ground with the display, introduce the hum bars. Try using the source device’s A/C adapter instead.

Another cause is signal wires running next to A/C current wires. Take care to separate these two kinds of wires. If they must come close to each other, arrange the wires so the two kinds cross at right angles and then continue carrying signals or current. You may need to contact your installer or qualified electrician to fix this problem.

A third cause of hum bars is a strong motor or other interference-generating power-hungry device sharing the same electric line as the plasma set or its signal sources.

Q: Why is there no LED when a new unit is plugged in?

A: Most of our plasma sets include a semi-hidden master power switch, located along the bottom edge of the screen’s bezel. Our factory ships the panels with this switch turned off. You will need to switch the master power on.

Q: How do I get the unit to display closed captioning, split screen, picture-in-picture, etc.?

A: Your Fujitsu Plasmavision display will show whatever pictures the source device (DVD, set-top box, PVR, and so on) may generate. For instance, if your third-party TV tuner has closed-captioning, you can turn that on. The monitor does not have these features built-in. Please check your third-party equipment manual to confirm the source device has the capability you are looking for.

Q: Why is there a buzzing noise emitting from the unit when it is powered up?

A: Buzzing can occur if you run the unit where air pressure is lower than 800hPa (typically 6,000 feet altitude). A buzzing noise can also occur if there is any physical damage to the screen. If that’s the case, call your dealer immediately to arrange for service.

Q: I'm running Windows XP on my Plasmavision display. Can you please send
me, or tell me where I can download, the video drivers for this model?

A: Video drivers are part of the video card installed in your computer, rather than the monitor showing the computer’s images. Please check with your video card manufacturer. All Fujitsu displays are Plug-N-Play devices, so there are no drivers available.

Life Expectancy

Q: How long should I expect the plasma screen to last?
A: With normal household or business use, Plasmavision display images will still look great in 10 or 20 years time. Since the picture is made with phosphor, engineers can accurately predict the geometric decline of the phosphor’s potential brightness. Note that while the brightness declines slowly, the phosphors never “burn out.” Also, note how the rate slows over time.

The rate of decline points to a specification called “Life to Half Brightness” or LTHB. Plasmavision display’s LTHB, ranging from 30,000 to 60,000 hours, depending on model, is about the same as you’d expect in a high-quality, properly calibrated TV or studio monitor.

Keep in mind the screen itself is supported by electronic components, drivers, boards and circuits. As is the case with all electronic devices, components may fail. These can be fixed or replaced by qualified servicers.

Q: Do I have to change the gas?

A: No. When the plasma glass is manufactured the inert gas is sealed into the glass unit. The gas does not need to be changed or recharged, and will last a lifetime as it is inert.

Plasmavison, High Definition Content and the HD Ready Logo

Q: Is my Fujitsu Plasmavision display ready for high-definition content, does it comply to the HD Ready Logo?

All current 40-series Fujitsu screens, except for the P42VHA40ES, comply fully with the HD Ready guidelines set down by EICTA. In addition, the following previous generation Fujitsu screens are also HD Ready –

P42HHS30WS       P42HHS10WS       P50XHA10WS

In addition, the majority of Fujitsu Plasmavision displays will accept High Definition signals through the analogue component video connections. However, this appears to be a temporary solution to ensuring that the maximum number of people can watch HDTV. In the longer term, HD signals will move over to the digital connections with content protection support (HDCP) as specified in the HD Ready guidelines.

Plasma Set-up Tips

Location, location, location!
Although plasma displays have a viewing angle of 160 degrees, allowing you to position your plasma almost anywhere in the room, the screen should naturally be positioned square to the viewer’s line of sight for maximum brightness and clarity. The centre of the screen should be no higher than eye level (because we are more comfortable viewing with use the lower portion of the eye), and the optimum viewing distance is 4 times the height of the screen – so the viewer of a 42” screen would ideally sit about two metres away.

Make the best connection
In order to achieve the highest quality picture, make sure you use high quality interconnects. Cables from manufacturers such as QED or Chord will preserve the signal quality and reduce picture loss, when compared with cheap or standard cables.

Straight from the source

When connecting your equipment ensure that you always use the highest quality source available. There is a bewildering array of source ‘formats’: Newer DVD players and forthcoming set-top boxes and games consoles may sport digital outputs (HDMI or DVI), there will offer the highest quality connections. Beyond this there are a plethora of analogue connections: the highest quality is known as component video (broadcast standard), followed by RGB (using SCART), S-video, then composite video. You will find, for example, that it is usually worth the extra cost for the superior image quality you will get from buying a DVD player that offers either digital outputs or component video output.

Picture perfection
Situating a lamp behind the screen when mounted on a table top will help to reduce eye strain. Use a screen optimisation DVD such as Video Essentials to adjust the brightness, contrast and colour balance of the screen to give the best picture in your viewing environment. Taking screen optimisation a step further, custom installers often employ a professional screen calibration service – which will bring out the very best picture from your Plasmavision screen for a few hundred pounds. Please email plasmaservice@fujitsu-general.co.uk for details of recommended calibrators.

TLC
To ensure your screen looks and functions at its best, you need to ensure it is clean. To clean the glass use a microfibre cloth to remove fingerprints and dust, and use a small amount of a non-smearing window-cleaning fluid to break down accumulated dirt and fingerprints. Avoid using any form of furniture polish to clean the screen, as this will damage it. Regularly clean the rear air-vents (at least four times a year) to ensure smooth airflow; if the vents become blocked, the temperature of the screen will increase and reduce the overall life of the product.
