Here are symptoms for my Dell SX2210T LCD monitor:
Computer starts fine at first. After 10 minutes or so, it starts vertical flickering from left bottom (at least it seems rather strong on the left bottom side). After a while it subsides then starts again. Flickering is more apparent and annoying on dark background. Flickering does not go away during BIOS when restarted so video card should be fine.
I reviewed a number of threads on flickering problem. As suggested, I looked at all the caps (10x 220uf 25V) on power board. Although they were all Lelon caps, visually all looked OK. Anyway, I replaced all (10 of them) with new Panasonic ones. After replacement, screen was fine for 30 minutes or so but flickering started again.
Caps on logic board, where display outlets are located, also look ok. They were much smaller caps (maybe 10 uf 25v, I am not sure).
I appreciate your feedback on this issue. I have been searching for the past few weeks but could not find any similar issue related this particular monitor.
