Hi all, I was hoping for some input on a TV that recently started acting up.

This may be unrelated, but about a year ago the 1080p hdmi stopped worked (would flicker, flash, make a hazy noise,) but 1080i worked fine.

Last week, I turned my tv on before bed and there was this:

The top left corner has a blue bar that moves a few pixels each way. The picture on the screen goes double, triple, and bounces around. Sometimes it will go solid, but usually just flickers with the double/triple image. If I press input the picture appears to freeze (as well as continue to flicker) as I cannot see my selected highlite moving. I took a video, but unsure where to host it.

Edit: forgot to mention; sound works fine.

TV info:
Model: 50PZ550-UA
LG Plasma 3D TV
Manufactured: July 2011

Hope you can help, thanks.

Bga on the mainboard is getting loose( cracked solderballs)
The board is bending because off the heat and the coolblock sitting on top off it

Reflow the Bga or better replace the solderballs underneed it

When you done this put something underneed the board so it will not bend anymore
Something like a silicone coolpad or coolblock

Good luck
