Hi i am a bit of a novice when it comes to electronics and i seriously hope that somebody here can help me diagnose my faulty NEO GEO console Power Supply.
The power cord to the games console has three pins, two voltage lines (5V and a 10V) as well as Send. My Multi-meter reads an extremely low current coming from both 5 and 10v lines, we're talking 0.8, and after opening up the unit, i found nothing wrong with any of the capacitors, resisters and what have you.
However, i did spot a bulge in one of the chips, i have no idea what it is or what it does but it's marked "MA5558". could this be the culprit?
If so, could somebody please tell me what kind of chip it is and where i can get a replacement/alternative or upgrade? i would sincerely be in your debt.
