Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

The picture goes blank after about 3 or 4 minutes. I have to shut it off and wait a few seconds and turn it back on. It does this 3 or 4 times and then it seems to stay on.

There are a number of things to check here:

1) Verify that the resolution on the PC is set to a supported level for the TV. Usually the TV will show "no signal" if the resolution is out of range or the message "out of range" will appear.

2) You don't indicate whether you are connecting to a desktop or laptop. If a laptop, you may need to turn on the external monitor. This is done by using the function key and either F5 or F6 (the key should have a picture of a screen on it). Hitting this combination will toggle between the main screen with.without the external monitor.

3) Verify that the TV port is selected correctly (AV1,AV2 etc)

4) You will need a separate cable or the audio regardless of the system type. Also verify that the audio cable is in the corresponding audio input jacks for the video option selected.

If you have completed the above and it still doesn't work, please post the details about the computer being used and the exact cable setup that you have and I'll check into this further.


Thanks,
Dan

Tv trys to start. you'll hear audio for two secounds, no picture, then 8 flashing lights, repeats after a few secounds 8 more flashes etc,etc


There is a problem in the audio circuit or the high voltage circuits. Check IC406 audio amp, PS401, and 402. Check also the flyback transformer T8005 or the associative components around it or associated with the high voltage circuits on the D board. Try also unplugging the unit for an hour to allow the unit to reset and make the unit work. It sometimes resolves start-up issues with the unit.

Picture blacks out after a few seconds after turning on the tv


Anytime an LCD has a shade of pink, that means the CCFL lamps are about to go out. Now that you have a black screen, I'd say you just need some new bulbs.
