Unplug TV, take off the back. One each board there will be capacitors. the tops are flat unless one has blown then it is bubbled up. If you find one that is bad, copy the number and search the internet for a replacement. Unsolder and remove the old one ( there is a line drawn on the negative leg, mark the neg side on the motherboard so you can replace the new one the same way). Now solder the new one back onto the board. This worked for my TV, hope it helps

SOURCE: volvo V70 electrical problem
had the same problem with an s80 this week- no warning lights nothing. was the regulator. when you have it fixed cancel all the trouble codes as when voltage is low everything registrs low signal input and makes the car go into get me home mode.

The voltage is regulated by the pcm (power control module ) on the truck. You cannot make any adjustments, removed or tampered with in any way to the pcm. Only a dodge dealer can check it out to see what the problem is with the pcm. Hope this will help you.
