VND acting up

LLUncoolJ:
This guy know anything about pinball...so that he can catch any obvious ---fudgesicle--- ups I make while ordering? I'm basically at the mercy of the numbers I find on the original parts.

Being a novice, I think other novices would be well advised to stay away from the more obscure titles. There just isn't much help out there. The pinball repair page was for titles up to 1995. This one is a 1999 and nothing looks the same as his pictures and descriptions. Not to mention, this one is such a short run (1100), that parts are non existant. Try finding glo-balls...and bring your American Express if you do find them. BTW, I have 3 spare balls for sale.  ;)

yah being newer is a little difficult to diagnose, since people havent had much of a chance to fix them yet.

You could be right.  All though it could really be about 20 different things.  Could be connectors loose, wire losse, cold solder joint anywhere on the capitors, rectifers, connector header pins, a flaky diode, etc, etc.  For all we know there could be acid dripping batteries in the cpu.

So is the concensus that I have a +5 Volt problem? Seems like most of you think that is a place to start. I am going to start with the PBJ idea of a cruddy connection. I'll inspect and try to clean the connections on the I/O power board. See if that does anything. I didn't notice anything with the batteries, but what the hell, I'll pull them out and replace them. Since the capacitors seem like a fairly easy solder job, I'll move onto that next if need be. After that, unless I get more suggestions, it looks like I'll have to call in the cavalry.

We had my kid's baseball team party at our house over the weekend and one of the parents used to service pinballs. He got all spanky and wanted to find a board from another machine and reprogram it. I think that is putting the cart before the horse myself, I don't think the board is fried by any stretch. Needless to say, I'm not sure the dude is trustworthy.

PBJ, please change back to the fat cat avitar...is nothing sacred?

Q*Bert_OP:
I assume you have a digital volt meter...anyways, in DC mode, place the red probe on the +5vdc test point, and the black lead under a ground strap...get close to +5v? Now place the meter on the AC setting...see any significant voltage? If you see more than...say .2vac, you have a capacitor problem...if not, change out the +5v rectifier, I have fixed 3 late model Sega driver boards with failed rectifiers in the past year...this problem seems to be quite common these days...
