Punch-Out!! restoration (Complete!!) - new bezel!
Spyridon:
Fired it up to play a game....Crap!
Lower monitor has just a horizontal line through it. Looks like my cap kit was unsuccessful!
Any suggestions on what to look at to fix this?
2600:
The Sanyo 20ez has a test switch in the middle of the PCB. When this switch is on you get a horizontal line. I'd try that switch first.
Also, I'm pretty sure that the batteries are for High Scores. You may be thinking of the Vs. Games which are for book keeping.

Yeah, I tried that switch. No change.

That's correct. SPO only saves the top 20 scores and the remaining 30 scores reset to default each time the machine is started. PO saves all 50 scores.
ChadTower:
Double check the orientation of all of the caps you installed. Then reflow the solder joints and reflow pretty much any joints you feel like reflowing. When you handle the chassis roughly enough to do a cap kit it's pretty common to crack a couple of ancient solder joints in the process. No need to panic just yet - this is not a big deal yet. Pay particular attention to the joints on any pots on the board - reflow those no matter what they look like. Those crack most often.
