Monitor/TV Samsung P2770HD Vertical lines and "flickering" after 5 min.

[EDragunov]

Hello all,

its my first post on this board.

Im having trouble with my monitor.

Im a noob in electrnics so if someone could help me identify the problem.

After a while (5-10 min) monitor gets vertical lines and flickers... on any video input or TV.

All caps on PSU look ok no bloating standing straight.

I can post pictures or video on request.

Thx in advance...

Caps don't necessarily have to look bad to be bad.

Post some images and we'll see what we can see.

If there's only a few primary suspects it may be worth replacing them just to check (or to temporarily parallel them with another good cap to see if that fixes the problem).

However problems starting after a while may also be heat related. Is anything getting hot? Is there a fan that's not working? Are there vent holes that are covered with dust or have no access to free air?
