Hi my Hisense Plasma tv 106cm PDP4220EU fel down and cracked the screen inside after that I just tested it it's only coming On and is playing you can change all the channel its working properly only that no picture ??

What is the exact model number

Sound like the tv's power supply is failing

Press "9" button .

If that does not clear it do a factory reset by way of the menus.

Hi, Try unplugging it for 1 hour. This will reset all settings to default. This may fix it. if it does not, take it to TV repair.man. Good luck

use these service and repair manuals, to troubleshooting procedures.

sounds like a resolution problem.
setup your pc on a different monitor and set the resolurion to 800 x 600.... then shut down and try yoy plasma again.

This worked for me

Hi Amhouston,

Can you turn it bak up again, manually or with the remote?

You most likely have image burn in on the display if it is not in a straight line. If it is in a straight line than it can be dead pixels. It is most likely the first issue I saw this same issue at work with an HP plasma TV.

normally the line down the center can mean that the lcd has become disconnected from the driver circuit. or that the driver circuit its self which is mounted to the edge of the lcd has blown out some of the drivers,
it is not usually the video sync circuit that is bad in this case because the whole screen would tend to be dead.
