Philips 37PFL7662D/12 image degradation

Hi.
It works but sometimes the image goes crappy with color changing, fading and ghost effect expecially in the right side. Then it works again. Then crappy... Good image and bad image not seem perfectly separated. The issue seems not related to cold/hot. May be the t-con? Bad solder joints? Heat gun?
I have a video of the behaviour of the tv. Can I link yt?

EDIT: Some screenshots. In the first and last it works.

Very common issue, it is a tab bond problem. If you have not heard of it before:

Thanks, didn't know the issue.
I noticed that those 2 mini-boards seem bent just near the flexible cables. Those flex was blocked by coils glued (biadesive) to the frame. Now 3of4 are unsticked and i think because flexibles so squeezed between the two board and the glued coil act like a spring.
I'll take some pics.

Confirmed.
It's the first tab to the right looking at the screen.

Well. I'm trying different solutions.
Plastic tubes not work, they deform after few on-off cycles due to the heat and stop to make pressure to the tab.
Now i'm testing this:

The typical fix that people use is part of the inner tube of a bicycle tyre, or the thermal pads that are found on the back of T-con and plasma sustain boards. Paperclips risk damaging the tab, I wouldn't recommend such use.

Thanks for you reply.
I'm not using it as a paperclip but i bent it forming two legs that push against the metal frame.
Obviously that part of the board is all tape insulated. It seems to work.
I feel like MacGyver....
