I have something really strange going on with may funhouse. when I got it it was trashed, replaced the mph and driver board with rottendogs and it cleared up all the issues it had and has played flawlessly up until the other day. I have the game out on location and go to check on it and all the feature lights are out and all the solenoid fuses are blown. I looked at everything that I could and nothing felt hot or burnt. I replaced the fuses and everything played ok. So I took the game home and started checking stuff out and found that every single controlled light was melted or started to melt and 2 of the white flashers basically blew up. Also rudy jaw isn't working any more and the Rudy optos and the staircase optos isn't working either. I took the boards out and looked to see if there are any burns or melted areas on it and everything looks fine. I have no clue where to start on this. Im not sure why there was such a huge voltage spike. The other games had no issues.

When I replace the lights everything works fine. My understanding is that the fuse should have popped before it let the lights melt or is that the downfall to leds? I've literally never had a bulb melt before. Im wondering if something happened in Rudy to make this happen, or the opto board went bad or something. any advice would be greatly appreciated.

Ok so is there a way to fix that? Or prevent that? I get rottendog are not the best out there but it’s what was available. I have the original board that was repaired but it still had issues that needs fixed

Could something with the high voltge board at the bottom side of the pf be part of the problem with the optos and the leds?

I checked all the test points and everything was good. That’s what I don’t get. Some lights are melted more than others but if you replace them they work fine.

I thought about something with the surge protector but if that was the issue wouldn’t the other games on that line have issues as well? It’s like there was a massive power surge but not big enough to do major damage.

Voltages all test good.

I think my newest concern is the optos are throwing error codes and not working. The game still credits up and starts a game and plays just fine, besides the lights which are fixable, the optos, and the Rudy jaw not opening

actually that could be a possibility

Just double checked funhouse and bride of pinbot and with the replacement led displays you remove the displays driver board which has the high voltage fuse. Correct? So that would eliminate the high voltage area to my understanding

All lights are fixed. Now to address the Rudy jaw and optos issues. Neither optos work and Rudy’s jaw only closes

The Rudy jaw only closes. The motor just clicks when it tries to open. With the spike in power could the high current driver board cause any of this? I’m pretty sure the optos are blown as well, so I will replace those. My main question at this point would be if replacing the high current board would fix anything

The boards may be bad, but what caused them to be bad? I just want my game playing

That’s what I’m thinking. I need to get a 9v battery and test the motor tonight

Tested the jaw motor with a 9v battery. Tests fine. No troubles.

I need to find the values of the high current
Driver board. I’m thinking something happened with that

Also Q30 will not let the mouth move up and down

TP 1 is read 13.3v

TP6 is ready 74v

So something is up with the 50v circuit

Well crap.

I ordered a new high current board and opto sets. Hopefully that fixes something

Ribbons are all new

Small update. If I jump the Moro while the game is on it will work fine for about 3 times that Rudy talks. Then It stops working again.

Well after replacing the optos and the high current driver board, there was no change in anything. Started looking into a lot of different things, basically anything I could that was related to the jaw and the optos.

I found that the connectors on j116 and j117 were we’re folded over so there was not connection with the wire but it was holding the wire in. Everything is playing fine now just like it was. Still don’t know why lights melted and fuses blew though.
