Big shout outs to user u/RoanPlayz on this subreddit for inspiring me to make this video!
Their written tutorial:
I'm working on a Japanese Launch model PS1. It turns on but it doesn't quite act normal on startup.
While a Japanese game is spinning, the Sony Computer Entertainment Logo drones on for a long while. I thought the laser was busted, so I swapped it with a known working one that is shown in the video here, but I get the same results. Not only that, but I get the same results when I don't have a disc inserted, too. The SCE logo just...drones for a while. It's not glitchy or laggy, but it goes on for a while before going to the BIOS menu.
That's not the weirdest part, the BIOS menu is sometimes unresponsive for seconds before it responds to my controller inputs. I swapped the controller ports with known working ones and the issue persists. The BIOS looks like it freezes then unfreezes, even when a game is NOT inserted.
I took a look at the motherboard and everything looks perfectly fine, I even used my microscope to find imperfections and I couldn't find any, not even a leaking cap in sight...
I swapped PSU's just in case it would make a difference but no dice.
So I need some advice. Is this a BIOS issue or a capacitor issue? I'm not entirely sure. If anyone can help me out here I'm all ears. I really don't want to dig myself in a miserable rabbit hole.

That's not the weirdest part, the BIOS menu is sometimes unresponsive for seconds before it responds to my controller inputs. I swapped the controller ports and my own controller with known working ones and the issue persists. The BIOS looks like it freezes then unfreezes, even when a game is NOT inserted.
