Aug 11, 2005 - 7 posts - ‎1 author Archived from groups: alt.tv.tech.hdtv (More info?) I have a Sharp Aquos 37" LCD TV(37GD6U). Every now and then I can turn it on,

Please check that the sleep timer did not somehow get set. If it's not the sleep timer, check if the panel stays ON longer after it's been off for awhile to cool down. Possibly a heat problem with the power supply or main board.

Few mins will not resetting tv and recovering power supply board from it protection modes that quick.Tries tv unplug,replug it back like about an hour later for tv resetting it back to the factory setting.The tv should get out it protections modes and might work again.If tv still have the same problems,than enough high currents got in the tv and kill ur tv power supply board.That the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power supply board for the replacement.

when i turn my 32 inch VIVIO plasma tv on it turns pff by itself. i want to know why this is happening

Sounds like the inverter for the panel for the left side is defective.

I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.

hi....Your micro chip is faulty check the voltage comming out of the 42nd leg it shuold be 13 volts dc if you are not getting that voltage replace the microchip.and the eeprom IC....
thank u rate me!!

that's D44 serial common problom,the cables connected to the panel made the problem

I've seen this problem before and if caught early (usually only a few pixels), its fixable. But if it has already started forming a "line" it might be too late and you might have a defective LCD panel. Most of the time, doing the factory initialization helps with this problem.

1. unplug tv
2. press and hold at the same time “Vol –“ and “input” button on the TV set.
3. while holding those buttons, plug the tv back in
4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go
5. then at the same time press “Vol –“ and “Ch. Down”, you should see the service menu appear (if it does not appear, try pressing the two buttons again, it needs to be exactly at the same time)
6. Then use the “Ch. Down” button to navigate down the service menu until you see “Industry Init” (NOT Industry Init +cause)
7. Then press “Vol +” to toggle it to “ON”
8. Then “/////////////////” should appear.
9. when the screen turns GREEN, unplug the TV. Wait about 30 seconds, then plug the TV back in.
10. Then continue on with the initial setup again.

no. It goes black, then about 5-10 seconds, it turns itself back on.
