2-3 second grinding noise on startup
There’s a short (2-3 second) grinding noise at the beginning of startup, before anything appears on the screen. I’ve taken the cover off and the fan is rotating ok. Any idea what it might be? It works ok, just worrisome.
I replaced the fan. It doesn’t work. I think I may have damaged one of the electrical ribbons, going to see if shop can fix. But also, still have the grinding noise. Video attached.
Is this a good question?
