I got an Amiga CD32 without colour on the S-Video output on my work bench. Schematic of S-Video ouput. I tested input signal (Base) of the Q282 2N3904 (NPN) transistor, result is ok (see picture above). Ouput signal: That’s not what it should be, so replaced transistor Q282, result after replacement is still the same. […]

CD32 – Totally dead
Got a Amiga CD32 for repair. It doesn’t work, no video output, power LED does not fully illuminate on powering up the machine, so no reset on Power cycle. First thing that came up in my mind was the voltage detector, replaced it and the machine boots again. But video output is totally mangled. Checked […]
Amiga CD32 – works for 2-5 minutes
Problem Amiga CD32 was getting black/gray screen after 2-5 minutes. Solution The voltage at the voltage detector (U14) was getting under the threshold of 4.3V, which causes that the reset signal was pulled down, and causes the black/grey screen. I replaced the Voltage detector (u14), the 10K resistor (R629) and capacitor (C629). The last two […]
CD32 – blown with wrong supplied power.. and a bug..
CD32 came in for repair, owner accidentally hooked it up to wrong psu.. Result, machine not working anymore.. R801 (0 Ohm) was broken, it was floating between 150 – 1M Ohms. Replaced it with new 0 Ohm resistor and the machine is working again.. tested all main components, and it seems no problems. I found […]
