My Funhouse has been through various states of restoration for a few years and is sporting a nice new PF. It was a project game when I got it.
I played it for a while but the gameroom went quiet. Now the kids are teenagers and are having friends playing again. (yeah).
Funhouse had some intermittent resets which I didn't address so now I am getting back to it. A few things I have noticed are that it isn't a warm up thing. It can be a bit random. I have had it happen with heavy play multiball and just normal game play. Sometimes it will be OK for a while and then it will restart and then do it again shortly after.
Voltage on the usual connectors is withing range. (J104 etc). I am seeing about 4.82v on TP2 at start up and about 4.9 after warm up. I know that this is a bit low. Is that voltage low enough to start the usual array of restart tests?
Here is the real question/observation. The driver board is a kludge of previous repairs, new solder joints a few wire jumpers etc. Do I run myself around working through all the usual stuff. I checked the solder joints on connectors and the like and reflowed some of them. The LM3232 looks like its been either replaced or resoldered and doesn't look that good. All in all I am not confident in the quality of the work.
At the same time, I am not keen on spending $ 300 on a new board. I am not averse to replacing it with a known good used board either.
Suggestions are invited.
