You need to replace the capacitors on the power supply. There is video on youtube on how to do it, when you take the back off, the cover for the electronic components and get to the actual electronics you will find 5 capacitors in the center of the black power supply.
You need to replace any capacitor that is bulging or leaking. I changed out the 1000uf 10V models with 1000uf 35V models from Radio Shack, and had to caniballize a old broken computer monitor for the 100uf 450V center capacitor.
Make sure you get the radial head capacitors, and it is really easy soldering work to remove and replace. I used a 30 Watt soldering iron and heated up the old solder until the capacitors would slide out, then resoldered the new ones in. The TV started and works like normal. Even the sound is louder
