Why is the image transfer from the laptop 'Dyed'?

A difficult problem where I do not know how to explain it.

It's about the fact that I wanted to connect my laptop via HDMI cable to the TV. A few months ago that was still normal and normal, but when I connected it today, the image was transferred, but the transmission on the TV had a pinkish stitch, that is, the color was not normal. Also on the 2nd Tested tv this was the case.

I have already used another HDMI cable, nothing helped. I'm starting to really get the ideas out. The laptop should transfer the image but also has no defects.

Does anyone have an idea / advice? I'm really desperate.

Try transmitting to another TV with the same cable. So you can tell if it's on the laptop or on your TV.

I have already done that, but the same result came out. But would not really know why it should be on the laptop?

Maybe a solution. Had until yesterday 4 mice that did not work on my 13 year old laptop. Last solution. Toothbrush in spirit and contacts cleaned on laptop. Behold. Mouse goes.

But important. Never directly into the device. Always indirect.

Contacts are dirty, cable is defective, output is defective etc… Clean contacts or sometimes another cable.

Something is broken…

Due to their compact design (high temperatures of the components) and their mobility (shocks, danger of breakage), especially laptops are much more at risk than desktop PCs. The useful life is about five to six years. According to this, 25% of the users require a new purchase due to a technical defect.

In the first year already one third of the notebooks are defective, after three years about 15 to 25%. This number material is already a bit dated, namely from 2009, newer numbers I have not found so far.
