PS4 Pro won’t power on, roach infested

Bag that thing and roach bomb it first!! You don’t need to take it apart for this part since the goal is to bomb as many as you can before exposing them and seeing how many survived - DO THIS IN A OPEN SPACE; NOT YOUR HOUSE/APARTMENT! After you roach bomb it, then you’ll need to take everything apart and clean each part individually. Make sure you take the DVD drive apart and clean that separately, along with the lasers. The problem with roaches and the PS4 DVD drive is they hide in there, and the lasers get dirty. You may need to replace the DVD drive. IT WILL SMELL MUSTY; don't ask how I know. Greased Lightning Classic will get rid of the smell with no problems, but only use it on metal and plastics. The main thing it does is it removes the smell so the roaches come back. Do this now, or it’ll become infested again.

After you clean the rest of it up, it’s probably a power supply issue so I’d start there. Roaches seem to love the PS4 power supply, so focus on that first to see if the issue is deeper than something simple. Yes, you may be able to clean the power supply, but I would not recommend even trying. They usually touch a capacitor and kill themselves, and it’s dangerous if you aren’t careful.

If it’s not coming back with a clean motherboard or a new power supply the roaches killed it in such a way you’re not going to be able to easily fix it. In addition, almost all shops will tell you no and refuse to service it.
