Can someone help me out here.

A friend has a Popeye upright that played fine, but the picture was squashed & small. Together we carefully removed the Sanyo EZ monitor, re-capped it (I've done a dozen capkits, including two EZs) and audio board with one of Bob Robert's deluxe kits. We verified each cap's rating and orientation, worked from the top of the list to the bottom.

Got it back together (with no spare screws left over) re-connected all the connectors, again making sure the molex connectors matched up. Plugged it in an *POP* (a small match-sized flame was visible briefly inside the board cage.)

We didn't touch the PCB set...or disconnect the edge connector.

Here's the list of known toasted components, on the CPU board:
- Q9: A1015 (was busted open, exposing metal inside the casing)
- R67: 51 ohm
- R66: 330 (guessing on the R number...it was the one that wasn't legible,
but the value was)
- R63: 100
- R62: 510K
- R64: 510K
- R65: 5.1K

R67 seemed to be the worst of the burn victims.

So WTF did we do wrong!? Uhg-uhg-uhg-uhg.....


Thanks,
Dave

Can you post a pic of the damage, parts side and solder side???
 
You killed the Sailor Man

You mixed up the "JB" and "JC" connectors on the monitor's audio amp when you put it all back together.

Each plug fits the others' pins, but they are labeled JB/JC. This effectively puts power through your audio-out on your game PCB - not good. At the very least, the audio section of the game board is now dead (and will require extensive and difficult repair.)
 
i may have a untested/missing roms popeye boardset, you can probably use it for parts if needed, lmk if interested i can search for it.
 
JB & JC will fit each other?! Never noticed that! So much for Poka-yoke!

Oh yes. You have to be very careful with those plugs. Which is why any time I'm directing someone to fix a Sanyo I always try to include that warning, along with the usual warning about the isolation transformer. I never really thought about it either, since I've never actually mixed them up (they're labeled), until I saw someone do it and blew tracks off the game board.

It's in the sticky thread.

Worst case scenario - I have a fully-working Popeye boardset listed in the For Sale section...

Funny, cause I must have taken that audio amp off and on 40+ times when I was fixing it. I got to the point where I could have made that mistake after doing that so many times, but I figured the connectors were so you couldn't do that.

Glad I didn't!

Bally - Thanks - I bet you're right about the JB/JC connectors...will check it out...frak!

KI4 - Thanks, I might take you up on that. I could have sworn I had a spare Popeye boardset myself...it *might* be on a shelf downstairs...heading down there now...

Let me know if you want to part with that board, I may take a crack at fixing it.

I'm glad I read this thread. I've never mixed those two plugs up before, but I never knew it would be a big deal if I did.
 
You nailed it.

I switched (corrected) the two plugs, replaced the 6 blacked resistors (although 4 of the 6 tested out fine...replaced them anyways) the two transistors next to them...and no sound....pulled the board, and replaced the AY-8910 on a hunch and sound! Played a couple games and all seems well...got lucky this time!
