Upon starting game numerous errors, traced back to Fuse F116 blown. Replaced fuse, played for a while, blown again. Replaced BR5 and C30 filter Cap and again played for a while, and boom fuse blown again. When played from a cold state, game plays 100% for about 10 - 15 mins, then fuse blows, so definitely heat is causing something to fail. I really thought I had it fixed with the BR5 and C30 replacement, but no joy. Any pointers what and where to check next? Thanks for any help.

Thanks for all the suggestions, I will report back once I have had a chance to try the ideas.

OK, I turned on game and came back in about an hour and found the fuse blown. Did not play the game, so definitely heat related (I would think). I imagine these are the hardest to find. I did not find any of the Bridge Rectifiers hot or other components that I touched on that board hot. Now what? Bad trace on the board that opens when heated/expanded? Why would that blow a fuse if that's the case? Thanks for any additional input.

Swapped Power Driver Board with Twilight Zone Game and Fuse still blows during game play so probably not board but something else.

I did replace all the lighting with LED last year and also added LED strips at the ball trough and the back of the play field as well as around the speakers. I also added 2 LED spot lights on the playfield (they get their power from lamp sockets below the playfield). The LED strips get power from J117 and J118 via pigtails. I disconnected all and played over an hour no blown fuse. I reconnected one set of LED's and no blown fuse. Once I reconnected all the LED strips after a while BLOWN fuse. So I am assuming this is the culprite. Too much draw? Although I would have thought LED's don't draw that much. Is there another 12v source I can split up the LED's?

Also, I noticed that my Display during play would get corrupt (unreadable) then come back, as well as sound dropping out and coming back, especially at the end of the round when it tallied up the end of the round bonus. May be totally unrelated.

The odd thing is, I have the same mods on my Twilight Zone without these issues.

I bought a kit from Pinballbulbs.com and that's where it shows to power them from. Is there a better place to power these?

Here is example of installing the back LED strip

my display was acting up even when all the LED strips were disconnected so maybe that is different issue? Didn't happen until I had played for nearly an hour so boards certainly were not cold anymore.

are there some places on the board where I can measure to see if that is the case?
