Hi everyone,
I've got a Chimei 19" Monitor (CMV938D) which has a backlight problem, under no light, you can still barely see the display.
Symptoms:
Turns on as normal. Detects input fine (as evident from green led light), goes to standby if no input detected (as par normal). However, the backlight seems to be dead.
Cap info:
Big black cap: 120uF, 400V 0615(M) 105C(AQ)P
Brown cap (bottom-mid): 22uF 50V, P61?, CapXon
Black cap (top-right, lying down): ?uF, ?V, P614 VENT KF 105C, unknown brand
Black cap (left of the cap above): CapXon, 220uF, 25V, P616 VENT, KF 105C
Black cap (right of the lying down cap): CapXon, 220uF, 25V, P616 VENT, KF 105C
Biggest Green cap: Taicon, 10V 2200uF
Medium green cap: Taicon, 1000uF 10V
Smallest green cap: Taicon, 25V 330uF
Black cap between green caps: CapXon, 220uF, 25V, P616 VENT, KF 105C
The green caps and the biggest black cap looks to be fine with flat tops.
However, the other black caps do have a slight bulge at the top, does this mean they are bad?
What can I do next to try fix this problem?
Thanks.
