Hey guys,
I have a Hanns G HG281D 28" 1920x1200 5ms monitor that has recently started to show symptoms of a bad inverter ie: the screen would show grey lines of brightness (flickering kind of) the icons on the desktop would look as if they were being shaken. Also, randomly the screen would turn off but the power led light would stay on.
So I pulled the monitor apart and looked over power board, inverter, and lcd controller for bad capacitor but didn't find anything bulging or leaking. I ordered a replacement inverter from ebay but the symptoms were the same. The likely hood that I have two bad inverters are slim i would think but you never know.
Onto recapping the inverter. All 4 of the caps have T0735 105 PET on them but that's is it as far as markings. Do you guys have any secrets of telling what capacitor I need to order. I will be supplying pictures shortly detailing what exactly I'm talking about. I will also pull the power supply to get detailed pictures just in case you guys see something I may have missed. Thank you!
Something to note is that the screen shaking sometimes will settle out and the monitor works fine with no distorted shaking of any kind. When looking at the screen really closely while it's powered up I can see like faint flickering of white lines.
Sorry for the crappy pictures I only have my iphone. Will get better camera soon.
