Try to reset first if nothing happens we proceed another solution;

Resetting the TV

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can saved time.
1. Unplug the TV power cord from the power outlet for 3 - 4 hours.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;

Regards,
VOTIT

Hi, the vertical address buffer board is often located on the top rear of the display, inspect the ribbon cables connected to this board, and connectors.


If connector and buffer boards are ok, then it is the screen, probably a problem with the drive IC located on the cable attached to the panel, when there is such a fault, you get a loss of the drive signal on the part of the screen affected.

You can buy parts here.

If you decide to do it yourself, I also suggest buying the service manual, and as usual do it at your risk.

If you want to contact a repairman, validate warranty or purchase a warranty extension, you can call the phone number listed on the tv owner manual.

    You will find a board with a ribbon cable connected to the display at the top, approximately where you get the stripe. Either the chip mounted on the ribbon cable is faulty , or the board itself is faulty.
    Start testing the ribbon cable first. Then replace the board. This usually fix the problem. Only in rare occasion you have a faulty display, normally it is the cable or the buffer board.

There are 2 causes for this, one is the panel gone bad and the other is the buffer. The only way to find out what one it is is replace the lower buffer and see if it works. If it doesnt you will have a bad panel and the set will be a non-repair because the panel will cost more than the tv. If you want to repair it yourself let me know and I will give you the PN you need as well as instructions on replacing it.

    The one that will be causing the problem is the one that is in the same spot as the line. if the line is 15 inches from the right, then the board that is 15 inches from the right is the faulty board! Let me know if you need more info!

    If the stripe is 15 inches from the right when you are looking from the front then the part number you need is LJ92-00811A cost is $85 at partstore.com If the line is in line with the middle buffer then you need pn LJ92-00812A. And if the line is on the left when you are looking from the front then you need PN LJ92-00813A cost $85. You have a 50/50 shot of fixing it as the problem bay be the plasma panel itself. If the panel is bad the set is garbage, the only way to find out is trying the board. Let me know if you need more help! and if your still not sure what board to change email me some picture of the problem and i will tell you what board to change.

I'm sorry to say that those lines or interference are cause by a hardware failure and no adjustment can correct it.
If your TV is only 6 months old, still cover under manufacturers warranty. Call the manufacturers and ask them how to go about this repair and hopefully they will send you to an authorized service centre.
Hope this helps.

50 INCH HITACHI ULTRAVISION HAS COLOR DIFFERENCE ON EDGE OF SCREEN


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 !
cheers!
Vern

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.)

Plasma tv has developed a black stripe in the upper lefthand corner, about one foot long and one inch wide.


This could be a bad thing, hopfuly only a driver board has failed and need replacment , Now for the worse case, the panel has failed. If thats the case it almost allways cost more to replace the panel than to replace the set
