Internal display acting up

Hi everyone.

Last week, the screen on my Macbook pro 15 inch mid 2015 with dGPU had small horizontal bands running through the screen, and after restarting this developed into vertical lines, which seems to correspond to the image the screen should show (for example, the white apple logo at startup turned into a vertical white band.) At first I thought this was due to a bad connection between the screen and the logic board, but altering the angle of the screen did not change anything. Periodically, the screen would go back to normal, but then after some time the image would freeze and slowly fade into the glitchy lines. My external monitor works fine, so the graphics are not to blame.

I did all the nVRAM and SMC resets, and after a few hours it started to act normal again, and for the last week it worked fine. However, yesterday as i plugged it into a projector, the trouble started again.

Again, I tried all the software resets, this however has not worked so far, and what is new this time, is that whenever the screen does work, the images are burned into the screen, and the edges of the screen are lit up in an eerie way. It just seems weird that the screen randomly works and then freezes again, when my old mac had a faulty display connector it did not stop malfunctioning unless the angle of the display was changed.

I was wondering if anyone has had similar problems with this type of macbook?
