my first freebie in a while

i think this is good news for the pc. after doing some testing i think i've narrowed the problem to the pcb or wiring harness.
i'm pretty sure the psu is fine, the 24v line is showing 22v but i'm guessing thats good enough(correct me if i'm wrong here). all other lines are spot on.
after swapping connectors to the monitors the bottom one does work fine, the picture is better than the top one actually. after adjusting the top one i got the picture less squashed, but i think alans is right, a cap kit would do wonders for it.
i'm going to test continuity in the harness in a bit. if that checks out, it sounds like i've got some board issues.
so far i've gotta say i'm impressed with this nintendo cab. the parts are easy to get to, pcb is a snap to remove, voltages were listed on the psu, and etc. the overall build is better than most of the u.s. built cabs i've worked on, which seem to have a sloppy look when you open them up. reminds me of working on my sega turbo which also has a well thought out design.

I swear I had a reply about this. You *definitely* have to replace the caps. Sanyo monitor, right? Only way to bring it back.
crsdawg:
i think i should have initially described the lower monitor as "not having a picture", instead of "dead". before i had time to really get into it i simply assumed it was a monitor problem. the minute or two i had it plugged in at it's previous owners house wasn't enough time to troubleshoot. today i was able to look at it a little more closely.
i took the input wires that lead to the upper monitor and attatched them to the lower one, i also connected the lower monitors input to the upper one. when i did this low and behold the lower monitor had a picture(and a pretty good one) and the upper monitor did not.
from this i gather the problem must be downstream from the monitors, since the psu looks to be ok, i think either the pcb is not outputing a signal to the lower monitor harness or the harness is bad. i'm leaning to pcb problems since it's doing some other weird stuff (like not detecting installed game boards).
i still want to put in cap kits as the upper monitor has some issues and it's just a good idea. but since both monitors do have a picture once a good signal is supplied, i will work on getting the game up first.
i could do a pcb swap at eldorado games which is just down the road from where i live. i haven't decided if i want to invest $130 in this game yet. there is also ebay. i still need to rule out the harness as the culprit, maybe later tonight i'll get to it.

umm... I've been doing dual screen with MAME for some time now with plan old vanilla MAME.

Thats outstanding.... now I just need a second 35" monitor.....
