How do I get the Pengo Sound Control Panel Out?
I took a short look inside my coin door today to see if I could figure out a front way to get the sound mount out of the cabinet. I know I should be checking for loose connections, maybe I just need to test continuity and that is it. But I can’t really get my hands inside the cabinet much.
I haven’t drilled out the bottom coin door yet, and am not liking that idea. But if I have to in order to get at the remaining screws that hold the whole door in, then that is what I need to do.
Wizard of Wor Capacitor Problem
I got a tremendous reply about my Wizard of Wor capacitor problem. A number of the collectors emailed me back and said they could provide me with photos. Another one went one step further and helped me identify from the schematic that it was indeed a capacitor I needed and what it is called.
On the schematic (Page 166 in the PDF online document) within the shape of the component there is a hand written .1. That means squat to me. I didn’t see a corresponding components “shopping” list with the diagram, only a list of the IC’s and other chips. Well, this collector let me know that usually .1 means that it is a “.1 microfarad ceramic cap”. That doesn’t give me a voltage, but that was specific enough.
Component C21 is what was burnt up and exploded.
Pengo PCB arrived in Pittsburgh
Heard from Richard today. He got the PCB in the mail, and he was able to set it up on a test rig and check it out. He was getting the bars across the screen just like me, so I wasn’t crazy. He said one of the chips felt like it was getting hot and that probably means that it is bad. It may be just that simple to swap it out and have it work, so here’s hoping.
Once the holiday is done things should move fairly quick, and I could have my PCB back hopefully before I go on vacation. (Nearly one year after I got the silly game)
Wizard of Wor blown resistor
Made the effort to get down to Menuir Electronics tonight to get some replacement parts for my Wizard of Wor board, A084-90708-A961. I needed at least a resistor that had broken at one leg, and I thought I would try to find a replacement for the axial diode, or capacitor, or whatever the component is that blew up on my Wizard of Wor PCB.
I had printed out the schematics, but they appeared to be hand written, and weren’t a lot of help. I knew the resistor was a 2.7K, but that was about it. She couldn’t help me with the capacitors, but she did have a connection like the red one on the board that got melted with the long fingers.
I replaced the resistor and connector when I got home, and removed the blown up diode. I then got on the horn with another collector here in the area that has a working Wizard of Wor to see if he could help compare to help me fix what I needed. I sent him some photos. Then I emailed some other contacts to see if they could help me identify the parts I needed to replace the diodes.
