Re: Hanns-G HG281D, LCD Monitor no power
now i have changed the caps on the power supply with panasonic caps, but after some minutes it also gos dark, and makes noises^^
could it also be some caps on the logic board? because i have changed there some too,
and i also could try to change the caps on the inverter.
and if i turn it off and on, it works for abaout 30seconds to 1 minute then dark againLast edited by feil; 06-23-2015, 03:06 PM.Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
hello
i get the 24Volts, but im missing the 3,3 and 4,8V and from whats on the inverterboard stands, i think thats to start the inverter board.
so something on the power supply , a bad cap maybe? i have changed all of them and it was working for about 1 months.
do you maybe now what caps are for the 3,3 or 4,8 volt ?
thanks for your help....Last edited by feil; 06-12-2015, 05:25 AM.Leave a comment:

Hello.
yes you see the screen and windows desktop, so inverter or lamps, should i try a new inverter board?
it would cost me about 35 dollar. or only the caps on the inverter board?
and lamps changing is that even possible?
