Was playing champion pub today when it reset. It turned back on and told me to check fuses 101 and 106. Checked and 106 was open. Replaced. Still told me to check them. Changed out 101. Still told me to check them. Led100 and 102 were on.

Checked all connections and they seemed fine. Went away for a while, came back and turned it on. U23, u20 fried. Along with r127. Can anybody tell me the value of r127? Wpc schematic seems a bit off for u23 and u20 and I can't find r127....not sure where else to look.

Sockets might be f'ed too. What a great first day with cp.

Anybody have any similar problems?

Thanks a bunch.

Nm I found it. Anybody have this problem though?

Somebody has had to have had u20 and or u23 blow up on their wpc95 CPU board....can you share your symptoms and solutions? Had this game for around 3 hours and this happened. Not really happy.

Thanks. I'll look some more while I wait for my parts. I did just get it moved to my house.

Hmm hoping it was just a failed u20. Not seeing anything unusual on the coils or any lamps. No pinched wires nothing loose.

Hoping to relate the back box lamps with this somehow. Found some burned pins/sockets. Can anybody point me where to look in either the game manual or wpc95 schematics on how these might be related to each other (u20 and the backbox lamps). All I have right now is an iPad and I still can't get used to splitting/only having theory schematics.

Sounds like I just got lucky with this buy. Worked just fine at sellers house.
