T61 screen flickering

Hi everybody!

I have an old but so far very reliable T61, as a kind of kitchen and living room laptop.

Now, since a few days, the screen started flickering at a rather high frequency, it gets worse when I turn up brightness, and there is a weird whirring / buzzing sound, rather silent, but it gets louder with turned up brightness. Also, sometimes areas that should for example be white turn a bit pinkish or even orange, mostly just for a short time. Other than that, the picture is clear.

Any idea what this could be? At first, I hoped it could be just a connection problem, the plug could have gotten loose, but I rather sure that's not it.

So now I'm mostly wondering if exchanging the screen itself would do the job, or could it be the GPU that is about to die?

I'd appreciate any suggestions, and thanks for reading!

Cheers,Tom
