Re: Hanns-G HG281D, LCD Monitor no power

@jimmy1256 Try measuring the voltage at the power supply. If +5VSB is stable all the time (even when the monitor turns off), this circuit is OK, otherwise use better quality capacitors C601/602/603, possibly C707. If some other voltage fluctuates it might be regulators or one of the U(101, 102, 201...) chips. When replacing caps, I've almost broken a pad next to U201 once (as user Steven_C on this forum also did), so try checking whether there was some damage done when replacing caps. Might be something completely different, but this is something...

Sorry, the numbers of problematic capacitors on the main board are C80 and C83.

Re: Hanns-G HG281D, LCD Monitor no power

Just finished repairing four (4) HG281D monitors that all failed after approx 5 years of use. Two did not turn on at all, both had fluctuating +5VSB. Replacing the capacitor C603 of the power supply (22 uF / 35 V) fixed both of them.

The other two did turn on and +5VSB was stable, but did not get the signal (displayed "no signal" message). Replacing capacitors C61 and C69 on the main board (100 uF / 16 V next to a regulator) fixed them. Just a hint for other people looking for a quick fix and not wanting to spend more...
