LG 65lf5700. Power supply board but out even 40 volts to top half but bottom portion fluctuates voltage. I tried a used power supply from ebay...stated as working but I replaced and having same issue. Any ideas if it cod be anything else? I doubt two power supplies could have the same issue. Thanks
If you buying from ebay it's very possible for this model TV to have two power boards that are defective as it has a history of LED issues that damage the power board, a lot of sellers on ebay get broken screen TVs and remove the boards and sell them without testing or having any idea how a TV works, send both back you bought on ebay at the sellers expense if they were guaranteed working. Shopjimmy.com has a kit with both the supply and new LED's that will be tested and work, this set uses a couple different LED strips that aren't interchangeable, make sure you match correctly

Larry,
Thanks for the answer. Shop Jimmy only shows one part (power supply board) and it is out of stock. The ebay seller is trying to tell me that I might have bad LED's...how is this possible when the dimming correlates to the voltage fluctuations? Are you saying the bad LED's ruined the other power supply?
