Default Sharp Aquos LC-70LE650U weird screen, please help!

Got this from some office, it was on the wall in conference until started acting strange. I took it off the wall and transported home in my minivan. Plugged in the power cord, and What?! It was working fine, except for a few small white spots on the screen. Didnít use it for a week or so.
Now, a week later, it acting weird again.
It is responding to remote, but so slow, that previous content is overlapping next screen in transition. After I press some button, it takes couple of minutes until it will get there, slowly.
Btw, I was able to do a factory reset with volume down and input buttons.
Didnít help any.

Here is some pictures I took with 2 minutes intervals.
Please help me fix it, please!

Maybe take it down to where you can get at the side tabs, usually you will notice some damage, like black looking burnt cof (chip on film) or one will be hotter than the rest or bad connection or sum such.

Seems like you are having same problem as Norcal in this one, you could try his test there to try to confirm, there is still the save by Freakafter8 that you can try once you verify bad tab/s on one side: https://www.youtube.com/watch?v=IZQRVqtIfns

With right cable disconnected (facing from the back) it looks this way:

With left one unplugged it looks better, but still thereís horizontal lines in both situations.
What side tabs am I looking for?

Thank to nomoresonys and badcaps.net!
I got that panel saved by removing all tabs on the right side (as facing screen)
Btw, disconnecting these tabs from the circuit plug didnít show any clear results for me.
Only after removing, peeling them off the screen it was fixed.
I also decided to prime those open spots with liquid electric tape to avoid moisture getting there in the future.
Thank you!!!
