Lenovo L2240pwD ghosting or fade image

[robante15]

Hi, thanks for your help

I have a Lenovo monitor model L2240pwD, which in turn has an LG LM220WE1 panel

The problem I have is that after a few minutes on the image is distorted, like it fades or has ghosting.

I have never repaired an LCD so I have no idea what it could be, if you could give me your help I would greatly appreciate it

I attach photos of the board that this monitor uses.

Do you have the same problem using the DVI input.
What voltages do you have on U101 and U102 and do thy change as the picture fades.
Is there a power supply board for this unit or is it an external power pack?
