Wizard of Wor - started out with no voice, now game is stuck at a screen.. any ideas?
Picked up a wizard of wor cabaret yesterday. It was playing fine but just no voice. I looked into that issue - pulled out the game logic board and reseated the SC01 and the 2 40pin ICs. Tried it again and got the same result, but at this point, one of the sounds other than the voice was not working correctly - the lowest "organ-style" sound wasn't playing, but instead i was getting a sound you usually hear when an enemy dies. Then I pulled the audio amp, tested the pot for the wizards voice and changed the (2) 1000uF 25v caps, then I noticed 2 blown resistors at R1 & R4. replaced those (330ohm). I also pulled the CPU board and reseated the pokeys the z80. I also reseated all boards into the cage. I then powered her up. I was able to play a game (still no voice) but upon conclusion of that game, I ran into the following screen and I haven't been able to cycle it out of this screen since.
I've since checked the voltages on the PS. They were +5.25vdc, +12.43vdc and -5.10vdc. I adjusted them down to +5.01, +12.05 and -5.10 would not go any lower.
At current, I'm considereing replacing the sockets for the z80, the pokeys, the SC01 and the two 40pin ICs on the game logic board...essentially, anything I reseated.
based on the video, is there anything i should look at first?
thanks
