Title: SCDR2 damaged PCB repair: non-capactior ICs/schematic?
Post by: rogerxyz on January 22, 2024, 08:53:24 PM

Warning: extreme capacitor gore lol.

I got a junk Super CD-ROM2 and it's Seen Some Shit. Good likelihood this isn't repairable, but... I have all the capacitors I need and a nice capacitor map.

What I'd like to know is does anyone have a service manual, schematic, or other that would identify some of the other ICs by their part number? There's a couple in the super-damaged areas that may be easier to replace than to attempt to save if they're common enough.

In particular this pictured area, Q307 and most parts numbered 300-310 are likely toast.

If you want to tell me to give up, that's cool too, I hear you.

Thanks!

Ooof, that looks painful.  I hope you get it figured out and back in the land of the living.   :pray:
