PlayStation Development Network

Hey you kings, queens, jacks, and jokers of the PSXDEV Network, I have a Craigslist SCPH-5501 that's having issues reading CDs. It can load official discs, but streaming video or audio stutters. I installed a modchip (Mayumi 4 on a 12F683) and it can very inconsistently load backups, but they have the same stuttering issues. I did my best to calibrate the laser with the trim pot on the drive, but to no improvement. I purchased a "new" KSM-440ADM drive from a Hong Kong seller through Ebay, and it appears to have the same problems that Masmorra described in this thread, that is, the laser doesn't even recognize that there is a disc.

I don't want to keep purchasing useless parts from sketchy sellers, so my question is, where should I get a KSM-440ADM? Or if it's just the laser that's dying, what part would I have to source and replace? Or is there some other test or adjustment I ought to try? Thanks y'all.

I never had any luck with those drives either, they're really subpar... You can either buy a KSM-440BAM from TotalConsole or buy a used PSOne and take a gamble that the laser is still in working order.

I'd buy units there but not only it really becomes expensive through currency conversion for me but the shipping is the last nail in the proverbial coffin. What I did was actually buy a PSOne for playing, realize the drive was perfect but the console had some weird intermittent reset issues, then just put that drive into my fat PS1 (actually a 7501). In both scenarios you need a flat extension cable which is cheap and plentiful everywhere. Now my PS1 works even better than the japanese FAT one I used to have back in the day.

Ultimately, since it's a 5501, I'd recommend you buy an XStation ODE instead of going through this spare part hunt nonsense. I actually got mine last week and I immediately put my perfect PS1 into storage.

Yes true, i did ordered from eBay the "laser pickup (KSM-440ADM)"
this is the third order.
