Diagnosing A Faulty SEGA Saturn Console

Diagnosing A Faulty SEGA Saturn Console

This time on the Game Room, I look into a Faulty / Spares or Repairs SEGA Saturn Console that I have recently picked up off of eBay. See how I get on with it… do I get any success?

I have a Saturn that looks just like this, a Japanese white model I changed the SRAM for FRAM and now it won't turn on! No power going in despite trying 2 different ReSaturn PSU's in that work in other Saturns so it must be something else, not sure if I damaged a trace somewhere.

@lamtatyan says:

Thanks for your video. My Saturn is suffering the similar problem but I am not sure if it is due to the power problem as well. I would like to check the PSU as well but I don't know how to "ground" the PSU like you mentioned. Can you be more specific? Forgive me I am a electronic newbie……

@GadgetUK164 says:

My guess is electrolytic capacitors! That Neo Geo CD PSU I looked at recently behaved that way with the voltages dropping under load. Check the smaller ones first!

TOP102YAI will likely have failed (PWM switch). You can replace either the TOP202YAI (found in the UK version) or TOP102YAI (found in the 110/120v version) in these Yamaha manufactured PSU's with a TOP224YN. I've had to buy mine from CPC Farnell as I've received fake or faulty units via eBay when ordering.
Repaired 5 PSU's; 4x UK and 1x Japanese so far.
