My q-bert finally made it's way out of storage and into the new house. I fired it up and got the below: Ignore the black bars, those dont show when looking at it in real life. My PSB is putting out the right voltages, and all the LED's are lit. Help?

I have a new-to-me KT-2914. I re-capped it, and in the process found that the yoke was in pretty bad shape (flopping loosely around on the neck) and there were multiple burn spots on the board. Some weird things have been done (piggbacking caps, for example.) After the work I have a weird image...

I installed a GBS 8118 2:1 switcher to toggle between a 4XX:1 and a 60:1 multicade. Everything works great, except it doesnt switch? Regardless of which game I plug into which slot, I only get whats plugged into slot2 on the screen. If I unplug the receiver for the switching remote it toggles...

I bought a cheap Tron PSB as a backup off ebay. It was pretty roached when I received it, but since it was a backup I decided to take my time and rebuild it. I did the Roberts shotgun rebuild, and plugged in the power-in connectors (J3 & J6.) I did not connect the 3-board stack, and turned on...

I am attempting to R&R my spare Tron PSB. I've done the bob Roberts shotgun rebuild, but my board is fried at R104. All of those cement-box resistors tested bad so I want to replace all 3. I was able to source the 10 ohm 5 watt, but cant find the .16 ohm 15 watt or the .18 ohm 5 watt...

I have two different Tron 3-board stacks, one that came in the cab that I purchased and one that I purchased as a back-up off ebay. I checked the ebay purchase and found that the boards I purchased there are physically different than the ones in the cab. Specific to the SSIO board there are...

I bought a Tron that played perfectly, but the cab was in rough shape. After enjoying it for a week or two I tore it all down and did a full resto-mod. While I had it apart I installed the freeplay chip, did the NVRAM mod and also the attract-mode sound mod. I reassembled and fired it up...

I recently picked up a Tron and am in the process of restoring it. When I bought it the lower light fixture was missing and the bottom of the lower bezel was not attached. I picked up a used light fixture, but does anyone have a pic of how it all goes together they can share? I think I see...

I am looking for the blacklight fixture that goes below the CPO/above the coin door. It (and all associated brackets) are missing from my new-to-me Tron :(. Please email/PM me if you have one you are willing to part with. Working parts only please! Thanks :)

I installed one of the new 412:1 blue game elf PCB's in my 60:1. Unfortunately this particular one has a few 'adult' games on it. I went to the settings menu to turn those games off so the kids could play, but when I go to the sub-menu for selecting which games are displayed I get a TOTALLY...

I have a cocktail q-bert with an intermittent power problem I have not been able to figure out. All the threads I have read say that either the transformer works, or it doesn't. However, I have found that I am not getting power into one of my bridge rectifiers. Accordingly I am hoping someone...

I have a running cocktail q-bert that I installed a doyle multi-kit in. Now when I turn it on I get my "hello, I am turned on" and the knocker fires, but then nothing, and just a white screen. Feels like an installation error to me. I pulled the sound chip at PROM 2 and 6502 and installed the...

I have been rebuilding my new-to-me qbert for the last few weeks. I had pretty much everything up and running and dialed, kids and wife were having a great time with it. However, when I turned it on this evening, I got garbled sound and a few brief seconds of scrambled screen and then nothing...

Over the course of the last month or so, and with lots of help from folks on the forum and magugin I have been steadily rebuilding my Qbert cocktail. It's almost completely functional, except when the knocker is plugged in it blows the fuse at F21 on the PSB (still bird-dogging that one) and...

Picked up a new-to-me q-bert cocktail for the wife this weekend. She and the kids have loved it, but it has 2 weird idiosyncracies I am hoping you can help me with. When the knocker goes, it fries the 12v fuse. If I let the game run with no fuse in the knocker, then the sound works just fine...

WG 25" with color bleed, fuzzy picture & curl? I am a brand new owner and trying to dial in my first cabinet. I have had tremendous help on my first one with another forum member, but its time for me to stand on my own feet and seek help on my issues. Background: the cabinet is a 1993 MKII...
