Acer Aspire 3 A315-55G-565J not turning on with almost burning webcam

Good morning everyone.
I'm having some trouble with my Aspire these days. It literally got hurt and I saw a little curve on the keyboard, so I opened it to see if something happened in the internals. Everything seemed okay, so I reassembled it completely and tried to turn it on, but everything that I got was a totally blank black screen. I tried to connect it to a TV but when I moved it I noticed that the upper part of the laptop's monitor was super hot and I couldn't touch it because of the heat. Now i re-disassembled it and tried gradually disconnecting internal components to see if something was making trouble but none of the internal components looks to be cause of this problem, so everything that I get is a one second fan spin and a light buzzing noise coming from the CPU (that I always got when its clock ramped up) then it shuts itself off immediately.
Can someone help me troubleshoot the problem?
Thanks in advance,
Luca.
The specs of the laptop in question are:
Acer Aspire 3 A315-55G-565J
15,6" FullHD screen
Intel Core i5-10210U 4C with HT @1,6/4.2Ghz
Nvidia GeForce MX230
8GB RAM DDR4-2400 single channel
512GB Kingston NVMe SSD
For further informations don't hesitate to ask. I'll be at your complete disposal

Was it dropped or hit by something?

It wasn't dropped, it got hit by a desktop speaker which was on the tower of my other PC right in the zone of the enter key

Okay, so, there are some updates: The laptop in the end is working when connected to an external monitor via HDMI, and I've disassembled it completely being able to disconnect the webcam (after I ensured that the heat was in fact coming from there) It won't start anyways w/out the webcam on its internal display. May it be the screen cable causing this problem?

Hi SeaLukino336,

Try to do power drain,

1. Shutdown the unit.
2. Unplug the cables connected to the unit.
3. At bottom of the unit there will be a small tiny pin hole with a battery symbol close to it. Take a pin or a paper clip insert into it you feels like pressing a button hold it for 20-30 seconds.

This is a good because it means the graphics adapter is OK. As long as the screen itself wasn't hit, then yes the LCD/cam video cable could be

an issue. I'd try re-seating the connectors at the mainboard and base of the screen. The LCD/cam mainboard connector is located close to the RAM module socket so it's possible it was jarred by the speaker. The cam cable is integrated in the LCD cable and the screen itself might have to be removed to access the cam connector.

Ok, so, I've ordered straight away a new cable, so then in a few days I'll try to replace that and I'll tell you if it was faulty. It costed (an original replacement, with the same code written on the lable) only 22€ off of Ebay so I won't be worried if it wasn't the problem so I could keep it stored as these cables are very fragile and they can broke with even a very light hit or fall.

Good plan! The cable is also susceptible to breaking in the hinge area from wear and tear of opening and closing the lid too much.

Hi, there are some bad news: I've replaced the screen flat cable. Nothing changed at all: i've trashed the old cable just to ensure that im not using the old one, but it won't display any image at all anyways. I've also formatted the internal ssd, for ensuring that it isn't a software-related problem: nothing. Power drained: nothing. It would display only with an external cable on a secondary monitor (with the internal monitor's flat cable disconnected for making the external one the primary one). Is there anything that i could try on my own? If possibile I dont want to give it to a technician.

Please reconnect the new LCD video cable!!!! Make sure the charger and battery is disconnected from the mainboard before doing this. Then put everything back together. Then with both the internal screen and external screen connected and Windows booted, repeatedly press the FN+F5 toggle key combination to try to turn both screens on at the same time.
