Re: Dell U3014 - discoloured corner, shadow

I have tested a bit further today. I have re-seated all cables between boards, and ribbons between little board stuck at the back of a panel and drivers if i can call it like that above.
I've dismantled panel again and lifted lcd up to see nice and even backlight underneath. Doesnt look this causes an issue.
I rubbed along these tap bonds how you called them when monitor was on at both ends and was trying to manipulate them gently to see eventual issues.
None of these have made any change. Visually it is all in good condition....

Re: Dell U3014 - discoloured corner, shadow

Any clue whether it could be panel or electronics?
I've tried to press any visible ribbon when monitor was on, nothing has changed again. It didn't get better or worse what makes me hope it is not a panel.
Also picture seems to be divided in four horizontal bands on the right side with every band being darker at the bottom of it. I assume it would be hard to explain such an discolouration caused by backlight LEDs?
I would appreciate any suggestions as it seems to be decent monitor.
I must admit that stripping...

Re: Dell U3014 - discoloured corner, shadow

These cables were sitting tight. I have removed and cleaned them but nothing has changed at all.
Any other suggestions please?

Re: Dell U3014 - discoloured corner, shadow

Will do. Can I use Isopropyl on these?

I have acquired this monitor few months ago with dying backlight strips. Fitted new ones and all was good for a month or two.
Out of sudden issue poped up with right top corner being discoloured, sometimes it looks like colours being reverted, lighter instead of darker etc. Also picture is not so smooth towards right edge of the screen, with horizontal lines being visible, and slightly dimmed.
When system boots up instead of apple logo I get white vertical line in its place going from top to bottom.
Apart from this monitor seems to be working ok....
