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 CD Power Supply.
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?
any help on this matter would be greatly appreciated.
