PCEngine Duo - Audio extremely low!
« on: January 06, 2023, 08:26:18 PM »
Hello!

I just got a PC Duo from the scrap heap, and somehow it works! I  tested with an audio CD, and it spins and everything, only issue is the audio. With headphones, I can hear it faintly. Without headphones, if I turn my TV up to full blast, I can then barely hear it.

Any thoughts/suggestions?

Capacitors going bye-bye, recap ASAP before the motherboard gets damaged with leaking caps fluid.

And if the old capacitors have leaked, you're gonna have to carefully examine the circuit board near all those capacitors and look for signs of corrosion and leakage. It's super common for via holes to get filled with leakage. (vias are trace transitions from board side A to side B)
