37 inch lg led vertical lines while warming upt Can't Post
Someone know how to solve bellow issue:
When TV turns on, vertical lines appears on right side, colour warm red and they are not static. Also lines appears on bottom, not cross whole TV. The problem dissapers after few minutes and appear again only when TV turned on again after time.

My crystal ball can't make out the alpha-numeric characters on the back of the TV set from this distance. Unimpressed
Can you post pictures of the screen showing each stage of the symptom?

No idea as to which LG LED 37" you are talking about.

IF does with the Menu too ... the last two apply.

Possibilities in ascending cost order:
1) Dirty ENDS on flat ribbon cables attached to TCON
2) TCON board
3) Panel

Thanks for your answer, what do you mean by "if does with menu too"?
And also if the problem with panel, can it be fixed, or need to replace?
About TCON, I see only 3 boards inside:
1) power
2) Main board
3) led driver
Do I miss something?

When you put up a menu screen are bars in front of or behind menu? or if you prefer,
When you put up a menu screen is it in front of or behind bars?

Tcon should be under stand bracket. Follow the FFC (Flat Flexible Cable) multi conductor cable from the Main board to it.

If panel, call a priest to give it last rites.

If I may chime in, would a bad panel end up working perfectly after warming up?

Couldn't it be a drifting component or perhaps a bad solder joint that reconnects due to thermal expansion?

One (of many) discussions regarding tabs.

Either way. Can work fine until warmed up OR works fine once warmed up.
