Any opinions on this one? T-Con or bad panel?

Update.
Worked good for a while, same issue when it warmed up. Think the problem is the t-con board as it reacts when tapped on. Already ordered another one as i found one cheap.
Pressing along the sides of tv or touching lvds cable shows no reaction.Comment

May still be the LVDS or ribbon cables, or the connections of these cables. Possibly poor ground connection of these connectors or poor soldering of the pins of these connectors. Ensure no dirt/dust/hair/lint is plugged in with the LVDS connectors.Comment

Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
Hello again! I have come back for some wisdom and hopefully for some guidance with this problem I'm having. The TV is a 4k 55" Sharp LC-55p6050u and the problem is every other line of the bottom 32 lines flickers out, comes mostly back, then flickers out again, and repeats this continually. The lines on the bottom right of the screen go out completely while the lines on the bottom left are affected so slightly that it's almost impossible to see it. There is a gradual gradient from appearing almost perfectly fine on the bottom left, to an obvious problem on the bottom right.

Hello,
i order a t-con because i had bad colors on my SONY KDL-40V3000 :
With the new t-con the color are good but there are vertical lines on all the screen :
I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)
Is there a way to fix the vertical lines on the new t-con ?
Thank you for your help

5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...
