HP Z30i monitor with white line down centre of screen
Hi, I have an HP Z30i IPS display. It is around 8 years old. It now has a white line down the centre of screen approx 100mm/4” wide. I turned it off one evening and it was working fine, the next evening when I turned it on the white line appeared. Prior to this it had been working fine.
The line appears when connected to computer and computer on. Nothing else appears of screen - no output from PC, or even when pressing monitors menu buttons.
I have checked the capacitors on the power supply module, and they all seem to look ok.
The LCD screen is manufactured by LG - model no: LM300WQ6 , The controller board has a number LM300WQ6-SLA1.
What is wrong with it, and what parts do I need to fix / replace ?
Thanks
EDITED added higher resolution photos of cables/boards
Is this a good question?
I had exactly same white line, but only when computer was not connected. When computer was connected there was reddish dots all around. I was already about to ditch the monitor, but took one more picture of it and suddenly dialog about not connected to a device appeared. After that I connected it back to computer and it seemed to work again. Except that the white light line remained on the background.

Hi, No I never found a solution. I have kept the monitor incase someone else does come up with a solution.
