Sharp LC-80LE661U 80 inch

[gavenb]

Hi folks!
I have a LC-80LE661U that had some interesting issues.
Initially, it would come on and show the sharp logo and would show normal static before shutting off.

I started troubleshooting by disconnecting the led lighting strips and turning it on. It would do the same thing - come on, show the sharp logo and shut off. After reading, it was suggested to replace the main board. That was replaced and the same symptoms resulted. After this and some reading, the parts cannon got loaded up. I replaced the power board, same issue. Replaced the Tcon board and now it just powers up the back lights and shuts off without even showing the sharp logo.

Any advice, or should I just shove this thing off a cliff?

Post clear straight on pictures of all the boards and one of the whole back as to see how everything is connected.

Maybe you have bad LEDs, symptom like this can happen. Your backlights are shutting off with the TV right? Or is the picture just going real dim. You have a LED tester to check them? But pictures also help us here too. I have personally had tvs turn on, backlight comes on, see logo and shuts down. The cause has been backlights, sometimes cause was main board, but you've replaced everything. So i would check there.
