Monitor repair

[remzy]

Does anyone have experience in fixing LCD monitors, power boards to be exact. Any suggestion what to look foor after checking capacitors, voltare regulators and mosfets and monitos still doesnt work?

Could be simple as a fuse, 1 bad resistor, a shorted anything...

No obvious signs means you're going to be busy

When you say "check", do you mean more than just "looked at"?

Have you confirmed there is power at the input?

Is the power supply turned on and off with a switch or a logic signal. If the latter, and that's fairly common these days, have you confirmed that this signal is present? In order for this to work, a smaller standby power supply provides power to (typically) the remote control circuitry. Is there power present there?

Yea. More than just look at. There is power at the input. I've found one smd rectifier dide that was open and I've replaced it and it work now. I've never before came across this problem.
