Sharp LC-70UD27U odd screen Can't Post

Hi All hope some on can help me out.
I have a Sharp LC-70UD27U.
See photo. https://ibb.co/nDfvrD9

Hope this link works.

"Blocks" are jumping,rolling and random. No on screen display.

Started Friday.
TV was fine then just did this no warning. lol.
So I unplugged let it sit overnight same thing in the morning.
Pulled of wall moved to garage same thing. Saturday.
Sunday pulled the back checked for bad caps, burnt smell, and re seated all connectors.
Low and behold starts working for about 3-5 minutes then same thing happens.
So I tap tap over all the boards noting changes unplug wait re plug and it works for 30 seconds to 10 minutes then out again.

Question to all FRC, T-CON ,Video board , OR???

I have not seen this pattern like this before.

Thanks to all.
