Hello Sharp TV experts
Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.

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... -
Hi everyone,
I've got a Sharp LC-55N7000U. It has a standbuy LED when plugged in, but powering it on causes it to blink 1 LONG and 5 FAST. Theres no display and no backlight.
Nothing I checked has that blink pattern for Sharp TVs and there's only one multi-button on the TV itself so that service menu trick involving the input button doesn't work either. Its a post-Hisense buyout TV so that probably makes sense lol
I've tried disconnecting the panel sides from the TCON alternating sides, but no change in behaviour even when the whole TCON is disconnected,... -
Just picked up this sharp tv not too long ago and it started not wanting to start the other day, giving me the notorious 2 long-5 short blink pattern indicating a power issue. I was able to force start it a handful of times (once the tv has fired up it has no issue running for 5+ hours). But now as of yesterday, no matter what I try to do button combination wise, I just receive the same blinking code.
So I busted into it and have done the following:
-Removed the power board and inspected for any bad caps, burn spots etc. Do not see any instances of such ... -
