Hi, long time browser - first time poster. I got my hands on a Sharp LC60C6400U and from what I could find on youtube similar models of this set have a 12V power regulator that fails called "KIA378R12PI". So I go ahead and order the part, install it and badda-bing my set worked right away. Only a problem - it failed after about 3 hours. So I re-attempted my solder joints and it was back in business, for a couple of days. Failed again with the same error code. I think to myself no worries I have 4 spares since I bought a 5 pack in case anything went wrong. But now after roasting the solder pads away I'm onto my 3rd regulator, the TV is powering on but I am realizing it's getting toasted by something elsewhere in the circuit.
I looked up the power board to replace it but it's no longer being supplied but apparently they still sell repair kits for it on shopjimmy. By the looks of it there could be as many as 16 additional components that need repair to get this sucker back up and running. https://www.shopjimmy.com/sharp-runt...rd-repair-kit/
Current voltages of my regulator (going top to bottom) are 28V 25.7V 0V 4.8V
Now these first two numbers seem very high for a 12V regulator so it's just a matter of time before this current fix fries, but that picture looks awesome. No lines, no issues, backlight seems ok. Just need a way to turn it on I think.
