Hi, I have this 2017 Google Pixelbook , customer donated to me after I managed to get her data off it. I'm kinda thinking I might want to try and fix but I'm not 100% sure its just the display because if I let if sit for a while it boots up normally with a perfect screen. However on reboot it does what is pictured, tilting the screen doesn't help. I don't do much work on these anybody seen this before? is it a mobo graphics chip issue maybe?
