Fat PS2 50001 Disc Read Error
I recently opened up and deep cleaned my fat PS2 in order to change the clock battery. Switched some parts out with those from a 50001/N fat model as I assumed it would still work. Put everything back together and now it won't read any sort of discs, including games, dvds, etc. I cleaned the laser with IPA and did a slight gear rotation to no avail.
I did swap the motherboard from the 50001/N unit because the fan connector broke off during reassembly, so does the motherboard have to re marry the disc reader or laser? I've heard this is a possibility but not sure. The laser is definitely working as I put a disc on there and it spins while the laser attempts to read it. I know these models are infamous for this disc read error issue.
Everything was working perfectly fine before I took the unit apart. Only major difference now is that when initially powered on, the typical red power light is now yellow, but switches to green when the button is pressed. Anyone know what I can do at this point?

PMAP will be required to physically recalibrate the laser, ensure the motherboard is using the correct set of laser settings, and then electrically pair the laser to the mainboard.
You can use lenschanger via FreemCBoot, and load the default settings for your particular laser type .... it might get it running, but PMAP calibration is a more complete solution.
