So my laptop is Acer Nitro 5 An515-43. I usually remove battery and do the stuff. But yesterday I forgot to takeout the battery. And while removing the screws of fans that I was about to clean.. A screw fell on the smd capacitor and a tiny spark came. the capacitor was near to the bios. I immediately connected the battery and turned on but only keyboard light and fans are working. And display is not working. No output via hdmi too. What could have gone wrong? When I gave to sc he said that gpu is gone. But I don’t think so.. please anyone guide me regarding this? Motherboard model LA-J621P Similar schematics : Here
Here is the motherboard view.

Denom Parkour I think you really answered this question yourself when you said that “and a tiny spark came.” That screw most likely caused a short circuit. At minimum you will have to replace the component that got shorted out and then re-evaluate your dame. WE would need to know the exact motherboard number (should be printed on the board itself) to see if there are any schematics ertc. available for it. If you can fiosdn a number etc. on the board post some really good picture off the motherboard with your QUESTION. That way we can see what you see. Adding images to an existing question
Symptoms look like there is something wrong with the GPU, not necessarily the main chip, but also the GPU power line and so on… As mentioned you should find where the shorted(?) capacitor belongs (maybe is from BIOS line), replace it and go from there. Sadly if a lot of power went through to GPU chip (if it is the GPU) then it could be shot….
