Title: PC Engine Duo, No Video after cap kit
Post by: Nyder on September 17, 2016, 07:29:49 AM

I recently did a recap (My first) on a PC Engine Duo.

I used a SMD cap kit from Console5.

I've replaced all the caps and hooked up the unit while the PCB is still out of the case on my work bench.   I tested with a hucard and get no video.

The game starts to play the demo, I can hear the music and game noises.

I'm assuming there is an issue with the caps not making proper contact, can anyone advise which caps are responsible for video output to narrow down my search?

Thanks in advance.

Check the traces for the 470UF cap right by the power switch. The leads in the motherboard for this one can easily get pulled out when removing the old cap. You might need to bridge a wire or two to repair the connection.

Good to know, we'll see if it helps for the OP too.
