Having an issue with the back GI lights on my FishTales. I replaced 3 header pins/connectors played about 20 games, now the back GI on the playfield is out for some reason...also trying to sort out my f114/f115 error on my Bram Stoker's Dracula. God damn I'm starting to get very frustrated with these slutty pins...

See here for details if you can provide any guidance...

I dunno for sure if your problem is similiar to mine on my Roadshow but if you look at that thread on here theres some things to try. I think your cpu board is different than mine. You just dont wanna see ground short row 1. Then just burn the damn thing.
 
Yeesh - your luck sounds as good as mine lately. I would guess that you have a faulty TIP102 and/or TIP107 transistor bad in the lamp matrix circuit.
 
I used to fell overwhelmed by pin repairs but now im liking it more than the arcade games mainly because i dont have to fuck with monitors on them.
 
Is Dracula WPC-S? On my Whodunnit, there was a factory bulletin that upgraded the amperage of the F115 or F116 fuse. You might want to look into that.
 
Try this:

On the BSD, you're getting the F114/F115 message. Are the fuses blown? You may want to check/replace BR1 on the driver board... that is the other bridge locateed under that vertical heatsink besides BR2. If you've removed a board recently, make sure you plugged in the data cables properly and didn't miss a row.

Fish Tales... probably not a bad triac... they usually don't go bad that often. Check the GI from transformer wires inside the cabinet. Once in a while, the plug in the cabinet will get a burn, and not cause a good connection for GI power flow. These are the yellow wires coming back from the transformer into the head. Did a fuse blow that controls that Gi line? When you did the header pin repair, did you take note of how bad the traces were burned on the back? Check continuity everywhere. Look at J120 and J121 plugs on the driver board. When you repinned these, do any of the wires on the individual plugs share the same plug position (IE J120 pin 3 and J121 pin 3)? In most cases, these wires are not supposed to share the same positions, and you may be overloading that GI circuit, causing the fuse to blow. Don't rely on the manual... many times it is wrong!

If all of these check out, you might have a shorted socket in the line. Sometimes the tabs on the light sockets can fold over on each other causing a short that will blow the fuse for that line. Kind of a pain to find...

Good luck,

OK, read the threads on RGP (duh)...

Try taking the CPU from BSD and put it in FT. Not vice versa, since you have the issue with Drac. Change the game roms. See if the problem with 114 follows into the FT.

Thanks guys, I plan on swapping CPU's from BSD into FT..just need some more fuses when I'm on days off. You don't need to swap the roms..

Fishtales I just need to run some more tests..think I can get this one working, probably just a bad pin job on j121-3 or possibly a no continuity on one of the header pins. Also have an issue with no continuity to one of the triacs..so that could be a problem..

I'll let you know when I get it figured out...if I do..hah
 
Fishtales is fixed, had a bad trace from f115-11 on the driver board to the q14 triac, installed a jumper wire and the lights are all bright and pretty again haha..

Now onto BSD, that bitch! haha
 
BSD is now fixed too! U20 was shorted, and I had some solder splash on the board from replacing the socket. A friend I met that lives close by, helped me repair the board! Life is good!!
