DSE G3292 (Rebranded LG) 32" Plasma screen going black.

[bennz]

Hello All,

This is my first post to the forums, I hope someone can point me in the right direction

I have a DSE branded 32" Plasma that works perfectly for anywhere from 5 minutes to an hour, after this time the screen decides to completely turn off and stay off however the sound remains and the remote is still responsive but nothing comes up on the screen.

The LED on the front of the screen is red in standby and green when on. When this happens the LED stays green.

If I turn it off then on again it will go back to working fine until it happens again.

The T.V has the following internals:

Mainboard:

PS-7231-1-LF LITEON

So it looks like its an overheating issue, I had the heater on in my room and noticed it started getting more frequent (like every few minutes. I also noticed that the TV has a "Buzz sound". When I placed the fan over the vent on the outside by the YSUS the TV will stay on and the buzzing sound is no longer

Could this be something as simple as needing more thermal paste on the heat-sinks as the old paste may have gone bad? It was run in a fairly hot environment previously.

Any ideas? Still having issues.

The last couple thermal troubles Ive had have traced back to tiny smd resistors losing connection. You can try using a hair dryer to warm up areas individually and see if you can find a spot that repeatably causes shut down.
