Hi,

I am the happy owner of a 17" LG Studioworks 78T5 monitor.
I think it has around 5 years old. All went well till about 1 month ago when I observed that when switching on my PC there were 10 blurred vertical green/blue lines on the screen, easier to see on a black background (see
). After a while, when monitor is "heating on" those lines fade away, but not completely.

So I ask for your expert opinion: what is happening?
I have to mention that I have the schematics diagram of my monitor, so you may point to it as you wish.

Thank you in advance for reading this post. Your help will be greatly appreciated.

This is a tough one, eh? Nobody can't answer...

Bump.

Hi it most likely a failed cap some where as it reduces when warm.

Probably on Video HT rail or 12V rail to video board.
