Acer Predator ph315-52 Schematics or any photos in hd?

Gabolt04

Hi, today was my second cleaning after 2 years, but when I was removing the fan to remove it, I think I desoldered an important component, after putting everything back together the laptop turned on perfectly, only it didn't detect the screen, I connected an external screen, and it works perfectly, but it tells me that there is no monitor connected to the intel graphics, that is, I cannot use the laptop screen.

It's an acer Predator ph315-52, what I need is for someone to send me a photo or, if possible, the schematic of the pcb, to see what component I'm missing. attached photos.

It's very hard to give you details on the mobo of the PH315-52 even if we have the official Acer SG for this laptop, as the mobo captions pictures are not as detailed as yours above for that chip to be recognized.

That chip that you have circled in red, was not there, as and if you look at the similar chip below that, there is no capacitor besides that chip. You probably did something to the eDP cable, or you didn't disconnect the Main Battery FIRST before you started to dissasemble and disconnect the eDP cable, as if you didn't you could have shorted the eDP cable to the screen or even shorted the screen out. that needs replacing.

Check the eDP cable two plugs that goes to the screen and to the mobo and inspect the fine pins that these two plugs have, as they get shorted very easily.

This is the best photo I can get from the PH315-52x SG mobo for that chip that is next to the mobo eDP cable plug, as in the SG unfortunately that chip is covered up😁 by a black tape.
