Re: Hanns-G HG281D turning OFF on HDMI waving on VGA

Thank you guys for your inputs.
I have used ESR meter to test the caps on a logic board.
Also have cleaned the cables prior posting on this forum.
Now for the green line, strangely i have carefully pressed the screen with my thumbs and moved it a bit (the screen actually moves around).
After this the green line disappeared, this screen is a bit of a joke. Well at least now i can use it as a secondary screen so that my wee girl can watch movies.
Will let you know if the green line comes back.

Re: Hanns-G HG281D turning OFF on HDMI waving on VGA

thanks for your reply, previously i have replaced 22uF 400V cap on power supply board (it measured low capacitance). No ripple on any of the output DC.
Now i have replaced two 100uF 16V caps on logic board (got 60uF and 0.6uF readings for those). Please see the pictures attached.
Changing those two caps fixed blinking issue as well as there is no flickers or any other artifacts on the screen except the vertical green line.
Where should i look to fix that?
Much appreciate your help....

Hello everyone. I have been reading this forum for a quite wile now, loads of good information.

It needs good 30 mins before monitor back to normal (waves and green light disappear).
Now after monitor warms up (after an hour or so) i can sometimes switch the cable to HDMI and...
