Looking for a Zaxxon CPO. Daniel

Issue: dead screen clicking sound of over voltage. Well this was a tough one. Lots of threads on it but all seem to point to something different. Tested the HOT and it was shorted. Replaced and no change (can’t remember if it blew again) Replaced the Flyback. Blew the HOT again, I read every...

Hi, Wanted to get opinions of the current value of a dedicated working zaxxon. Had this for a long time but need to thin the beard out a bit. Thanks, Daniel

Hi, Realized this question should probably go in this section. Does anyone know what monitor would typically come in a Megatouch Video upright? Thanks, Daniel

Hi Everyone, I’m trying to find out some info on the Megatouch Video version. Can’t seem to find much for this one. If someone could point me in the right direction that would be awesome. Specifically I’m trying to find out what monitors came in the upright version and when the “Video” version...

Hi Everyone, I just bought a “working” BK 466 on eBay. This is my first time with one of these. Followed the instruction exactly but I think there is an issue with the unit. If it’s something simple I’ll just fix it rather than going back to seller. Basically, I hooked it up to two tubes that...

Working Tri-Sports PCB, harness, Trackball, and CP buttons for sale. I’ll throw in the marquee if wanted. $75 plus shipping for all. Or you can pick up the whole cab minus monitor for same price. Daniel

Working on a K7400 and the HV shutdown pot got broken when trying to replace a cap that was covered in epoxy. Does anyone know the procedure for setting this pot? I assume any pot with the right resistance will work. Thanks for the help. Daniel

I am working on my Qix that has no sound. I am relatively new to all this logic stuff so I just wanted to see if someone could confirm what I am seeing. I attached a pic of the schematic of the chips I’m looking at. I have tested U24/28 (4066) and I am getting toggling on pins 5,6,12,13. Pins...

Hi Everyone, I have a two Eeproms that I wanted to get some advice on. They are 2716 and 28C16. They were in a board that I purchased a while back and they were upside down. So, I assumed they might be cooked. I put them in my burner (AR-32a) and the burner says they are erased. I read them in...

My Vs board is acting weird. The aux side is fine. The main side boots to a free play screen and I can hit the 1Up button and it definitely registers as the push button message stops blinking. But then nothing else happens. Also if I try to change the DIP switches (to try to get it out of free...

Hi everyone, Haven’t seen this on a monitor troubleshooting flow chart but I plugged in the monitor and the fly back literally was shooting flames out of itself. Of course I shut it down. Took it out and removed the fly, checked the fuse and the HOT. Ordered a new fly back. Installed it and...

Hi Folks, I am close to getting my Qix back to life. I now have no sound or at least almost nothing. It does make a couple attempts at sound in the attract mode (when the fuse goes out on the drawn line). Not sure it’s the right sound as it’s been so long. Anyway, I have read a few threads and...

I have a red tent with Sharp monitors. When I look for a cap kit, there is reference to an audio board. I can’t seem to find an audio board and wondered what I am missing. I only see the main board and the adjustment board attached to it and the neck board. Just don’t want to buy a bunch of...

Hi Everyone, I have a Quarterback that I just fired up and am having trouble with the monitor setup. I wanted to ask for opinions on the four or five jail bars on the left of the screen left of the yardage markers. (The larger block is a iPhone issue). I have a cap kit on order but wondered if...

I have a Radical Bikers in very good condition that I plan to sell. I’m not sure what it’s worth. Opinions? Daniel

Hi I have a flicker on the left side of screen. I assume this is a monitor issue. Other opinions? Daniel

I bought an AR-32A a while back and have lost my manual. Does anyone have a electronic copy or know where I can find one? Also, has anyone lost power on their unit before who might point me in the right direction? Thanks for your help. Daniel

Hi everyone, I am trying to learn and have watched the repair videos that Adam has put up. I have a DKJr that has gone a bit south. On power, i hear the first sound and then a constant annoying sound that the volume pot can control. The screen shows blue letters/numbers. I did check clock but...

I have a Galaga that coins fine but the after playing the intro music to stage 1 it goes to stage 2 then the challenge staged. It keeps incrementing up without going into any of those stages to play. I have swapped must of the chips from the board but the problem persists. Anyone have this...
