Good Luck.

Blurry, purple bar across middle of plasma tv screen

Plasma screens are extremely susceptible to getting broken from any impacts to the face of the screen. What you are describing sound very much like distorted or dead pixels. It may not be a fixable issue, you may have to replace the entire unit or live with the purple bar. The reason you don't notice it as much when the screen is dark is because purple is on the darker end of the spectrum, and will be most visible in contrast to lighter ad brighter colors.

Hi if your tv is a dlp it might be an issue with the DMD board Hi,Yes your problem sounds like the DMD board.This is how it works: Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : Have a blessed one!

Pink bar across top of tv screen

This could be from 2 things. 1 is the optical block is going bad or 2 you got a peice of dust blown in from the cooling fan and its blocking the color filter internally. If you are capable you can take the tv apart and blow compressed air into the color block and remove the dust. Hope this helps

Run the PSA Diagnostics and Obtain the PSA Error Code

To run the PSA diagnostics and obtain the PSA error code, perform the following steps:
Shutdown the computer.

Press and hold the <Fn> key, then press and release the power button.
Release the <Fn> key when the lock lights above the keyboard begin to flash or Diagnostic boot selected is displayed in the upper right corner of the screen.

Release the <Fn> key.
The PSA diagnostics sequence begins.
After approximately 2 minutes the system produces a number of alert tones.
After the alert tones, the system produces either a series of low beeps or error codes.

PSA diagnostics will prompt for input during some tests. The resulting error message does not necessarily indicate hardware failure.
For example, input is required during the color bar test. Failure to input a response will eventually result in a timeout error: 1000-0333 Graphics test timed out waiting for keyboard response. This does not indicate a graphics failure has occurred.

Note the sequence of beeps or error codes.

Initialize LCD BIST Diagnostics

You can initialize the LCD Built-in Self Test (BIST) in two ways, depending on the revision of Pre-boot System Assessment (PSA) diagnostics:
PSA versions 3019 and greater run LCD BIST immediately after failing the color bar test, via user input of <N> or waiting for it to time out prior to generating the 3-3-3 or 3-3-4 error. PSA version 3019 became available in November 2005 on various Dell laptops. The PSA version is upgraded with the BIOS.

With older versions of PSA diagnostics prior to November 2005, LCD BIST runs after responding with a <Y> after receiving a 3-3-3 or 3-3-4 error code.
To initiate the LCD BIST on PSA versions 3019 and greater:
Boot to the PSA Diagnostics.
Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics. If the screen is visible, one will see the PSA diagnostics draw a series of multi-colored bars across the screen. When completed, a prompt asking if the pattern was seen appears, accompanied by a brief series of tones.
Press <N> or wait approximately 30 seconds to fail the color bar test.
Watch for the LCD BIST color generation and listen for the beeps every 2 seconds that indicate LCD BIST is running.
LCD BIST runs for approximately 20 seconds, then stops. The 3-3-3 or 3-3-4 error code is then displayed when the LCD BIST is complete. If LCD BIST does not initialize, then the system may not have been upgraded to PSA version 3019.
To initiate LCD BIST on systems with PSA versions prior to 3019:
Boot to the PSA Diagnostics.
Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics.
Press <N> or wait approximately 30 seconds to fail the color bar test.
The system emits a 3-3-3 or 3-3-4 PSA error after failing the color bar test. Wait for two iterations of the failure code and then press <Y>.
On a working LCD, the PSA diagnostics shows the following message:
Error Detected, continue testing? Yes or No or Retry.

Watch for the BIST color generation and listen for the single beeps that indicate LCD BIST is running.
Patterns of flashing color should appear on the screen. With every color change, an audible beep is heard. If the patterns of color do not appear, and the beeps are audible, an LCD failure may be the issue. If the patterns of color appear, a video card or motherboard failure may be the issue.

Thanks and Goood luck! =)

Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !

Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time.
We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.

GKar posted 2006 Oct 10 15:31 TooLFooL : i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...

I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )

This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)
