What is causing barely seen vertical line
I have a thunderbolt display that recently showing a barely seen vertical line (see picture) some kind of noise, there is nothing else wrong, neither color or picture.
I was wondering if its noise from power supply or logic board or T-CON board, the lcd is LM270WQ1-SDB3.
I dont have a schematics and can not find it either by googling (checking probe point with oscilloscope ).
