Question about Televison & Video
I have checked all of the voltages from the power supply and they all seem good and also checked then at the main board. I read a blog that talked about "re-balling" the video chip and I have done this process several time successfully on laptop motherboards so I tried it. It worked! but only from a few days... so I tried it again... same thing happened worked for a few days then dead again... I am only guessing but it seems to be the video chip so if the main board is replaced it should correct the issue?? Anyone have any thiughts or have seen this behavior before?? Thanks!!

You need to check the 12 or 24v source coming from the power supply to the inverter board, that's the board usually to the left and rather tall. Get your meter set, then turn the set on and see what happens, if the voltage comes up and then shuts down, you'll need to pull the plug for the inverter and measure the voltage again. If it stays up you have a bad converter board, if not then it's in the power supply, that's good old fashion trouble shooting from there on.

you are correct power pack has bad capacitors, doing what you did may have damaged other components in the power pack, or main video board. let me know what you want to do.

I would suggest trying to repair the board first before buying a new one (unless you get a great deal on a replacement one). Its possible it was something simple like a fuse or busted capacitors.
Open up the TV and take out the power board and check it for any busted capacitors. Also check the fuse(s) with a multimeter. Try replacing everything with a soldering iron (shouldn't cost more than $10 for a fuse and capacitors). Try and see if it makes a difference. ONLY DO THIS IF YOU ARE CONFIDENT and SAFE with that type of work.
