Re: Sharp LC-55LE643U, bad gate drivers?



Yep, that's along the lines of what I was thinking. The tab feels like it's still securely connected, but I'll have to take the bezel off to get a better look at the IC and the panel and see if I can tell why it went out.



I'm definitely "unclamping" the holders before pulling anything out. Also, I swapped the TCON board and all ribbon cables after the white bar first appeared. I did not swap the main board, though I do have a spare. Still, it's worth double checking to make sure there's...

Just received a busted Sharp 55" Aquos (LC-55LE643U) from a coworker. He tried swapping all three boards (power, main, TCON) to fix the problem, but it had the same issue. He was kind enough to give me the TV and both sets of boards for free, so I can try to get it working for myself.

Unfortunately, I think I may have made the problem (much) worse, but I'm interested to see if the original problem was fixable at all regardless...

Pictures show the issues:
