Re: Hanns-G HG281D, LCD Monitor no power



Got the 2 caps for the main board in the mail yesterday and replaced them. Great news, the monitor is working as new. No flickering, no 10 minute warmup,... everything back normal. I wonder now whether there were bad caps on the power board at all. Regardless, thank you for all the help. If I didn't find out about replacing just those two caps on the main board, I probably would not have gone through the trouble of taking it apart again.

For those reading this and having similar problems. Replace those two caps...

Great. Thanks. I made the order so hopefully next week I can give an update on the outcome....

Sorry if this is a dumb question, I don't know too much about electronics so I rather double check everything before ordering.Re: Hanns-G HG281D, LCD Monitor no power

I think I will try and replace those two then. Do you have link to a specific cap that you find worked well for you?...

Re: Hanns-G HG281D, LCD Monitor no power



I only replaced the power supply board caps (except for the large one).

I'm thinking of maybe going back and doing the other board as well. Probably I would order them from digikey if I had a list of all the caps I needed. There are also some larger caps running along the edge of the board attached to the screen, I wonder if I should replace those as well,... although I don't the cap values for that either....

Re: Hanns-G HG281D, LCD Monitor no power

Well... unfortunately I don't think it was a complete fix. I did notice that if I turn the monitor off after it's been awhile, then wait for it to completely cool down, and then turn it back on,... there was some flickering. It's definitely much better than it was before and I don't have to wait 10 minutes for it to "warm up." Maybe some other caps are going bad on the other boards? For now it's still very usable so I don't regret doing the work. If it gets worse I will probably try recapping the 2nd board.

[B]I FIXED IT!!!![/B]

I own a HG281D and for many months I had an issue that was described on here. It would basically take several minutes for my monitor to "warm up" and before it did it would turn on and off. After it was warm, it would then stay on. I basically tolerated this for a very long time (probably 6 months or so) and then on occasion it would temporary black out for a second or two depending on what was displayed on screen.

Started doing some research and found this thread. I was able to...
