Have had it since the dinosaurs I think 😀 Recently started skipping on some CDs but played them. After sitting for some time with no use, put it back to work and now it would read the CD, show the number of songs but when I hit play - it hangs there at 1 and 0:00. CDs I tried were all brand new.
What I did so far was to clean the lens with isopropyl alcohol, checked belts and gears, all looks ok.
Have a scope so can test the laser head but have no service manual for this one (will look around). Any other suggestions as to where to look are welcome.
I`ve read the SF-P1 in it is bullet proof but its like 27 years old already, perhaps replace it and all caps then check voltage and adjust?

1.Check motor shaft runout and disk height above lens.
2.Check for cracked gear on the sled motor. its may be hard to see.
3.Change R129 from 100k to 22k
4.Change C120 from 220pF to 470pF
5.Check TP03 CK to 4,32Mhz
6.Adjust P101 E/F Bal.
If not help, change C147, C148

Not had much time on this but thanks a lot for all input, highly appreciated. Will look it up tomorrow I guess 🙂
