How to define a loop or a matrix?

Question

Iron

Hello. There is a laptop. When turned on, instead of white, everything is pink, i.e. colors are distorted. After changing the picture, traces of the previous image remain. The train moved, nothing changes. When connected to a monitor via HDMI, the picture is normal. Yesterday I left it to work for about 30 minutes, then turned it off, turned it on and the image became normal. Then I turned it off for an hour, turned it on, and everything was pink again. I sin on the matrix itself, apparently when something heats up it starts to work as expected.

How to determine what is wrong? I don’t want to buy a cable or a new screen, and then it turns out that the problem was something else :)

It looks like a matrix, if you still want to check it - remove the plastic that closes the matrix, remove the matrix, in your city you come to a point that sells matrices (even in the regions there are services with spare parts), plug it in on the spot = profit.

After changing the picture - there are traces of the previous image

100% matrix
