Hanns G 19" LCD monitor Screen Problem

My monitor was working up till today, when it was turned on, i could hear a faint squealing noise coming from the monitor and about 1/3 of the screen from the right was grey and kept changing different colours every time i turned it on and off. the other side worked a treat but the right hand side was bad.
I opened up the monitor and plugged it in again, did the same thing and i traced the squealing noise to the power supply unit but cannot accurately pin point the source but its centered on the power supply board.
Could this be causing my screen to go funny?
And i aint sure if its any of the capacitors of the transformer making the noise either.

Got 2 pictures here, one of the screen and one of the Power PCB & video board.

    This is what the monitor looks like when powered up.

    Update-



    Upon testing the power supply, the squeal becomes alot louder when there is a load on I.E the video sync board but when i remove that, its only a faint one. When the Backlights are plugged in only , the sound is still faint and doesnt become louder.

Hanns g JC199D will not turn on, comp is on, try to turn monitor


no signal indicates a couple things... i suspect your computer isn't even booting up. reboot the computer while tapping the F8 key.... you should see writing on the screen... boot to safe mode. after it sucessfully boots up... reboot again... should be fine.

I think this should be a problem with the CPU and not the monitor, Is there a continuous beep sound coming , If so then there is a problem with the Memory.

Hanns g 19 inch monitor


No direct experience of this specific monitor, but LCD monitors in general seem to be susceptible to power supply failure due to the relatively cheap capacitors they use and the high working temperatures.

Turn it off, leave it for an hour or two, then take off the cover and look for bulged or leaking cap's on the power supply board. If the tops are not flat, they're probably duff, and need replacing with equivalent spec ones. Probably 105'C high temp - I got 105'C 470uF 35V ones for my monitor from Ebay at about a fiver for a pack of ten.
