I once had tis DVD initialization failed issue on one Phat PS2(cannot remember the actual model). It turns out to be the ribbon cable has two pin corroded away. After a trace fix, PMAP works again.

I have the same "CD TE LOOP GAIN NG: 127" error on a 50004 console, what does that mean? @AKuHAK
Console reads CD perfectly.

After a ton of research and understanding of what the source code does CD TE LOOP GAIN NG: 127 means the electrical adjustment for cd is out of spec. You may have a blown laser (mine was). Dont adjust any of the laser pots, and do mechanical adjustment first before the electrical one. You will get it as close to the readme value using the mechanical adjustment, when you are doing this you will be using just the spindle motor and dvd-sl and the white clamp from the top. You will adjust the big screw first and get it to the closest you can then the small screw. After that run the elec one with the proper disks, and it should ask for a cd, the dvdsl then dvd dl if done correct
