On the MPU board I checked the 5vdc and 12vdc test points at points 1, 9 and 10 (5vdc, unreg 12vdc and ground) and found them to be lower than expected. At the power supply (and also the connector at the MPU board) they read 4.98vdc and 13.48vdc, but at the test points they read 3.42vdc and...

Looks clean, except maybe a small patch by the 5101. Whats the best way to clean corrosion?

Hi All, I have a Firepower that isn't booting up at the moment. When powering on, both LED's on the MPU stay lit without flashing. From the write up on pinball.flippers.info, I removed the solenoid fuse and disconnected the Driver board and still got locked on LED's without a flash. From what I...

Yup, it's your if you want it.

***EDIT*** I increased the voltage to 5.35vdc and it works great. Hopes this helps others, this chip is picky! I just did this mod along with the freeplay mod, but it is not working. The freeplay mod is working great, but I am getting a RAM error for B2 3 out of 4 times when powering on. It is...

Those are a ton of fun, I've seen them all over Ireland.

Both PCBs have been sold. I still have the Pacman to Ms Pacman conversion kit

There was a short on the green transistor. All 3 of the pads are lifted and gave it enough wiggle room to short out on the heat sink. I fixed that and it help somewhat, I then turned down the green pot and BAM! it looks great:) I just need to degause the upper left corner, if only I had a...

Thanks guys. The heat sink was on there, I took it off to get a better look at the heat damage. It was loose and came off very easy, much easier than the other two.

How much for just the controllers?

Thanks and glad to see you are back! I definatly want to stay with the U5000 for the medium resolution then.

I just purchased a game with a U5000 monitor in it. It was displaying all red when I bought it. I have heard that the transistors on the neck board overheat and are a common problem. When I took a look, sure enough the pads on the middle one were completly black and the pads lifted. It already...

Luckily a local, Rob, has been kind enough and offered to take a look at it this weekend while he is over picking some stuff up. I was hoping to get some parts on hand and an idea of what needs to be done ahead of time. Wasn't sure if a new chassis that someone has for sale right now would've...

Thanks, but not the answer I was looking for LOL. I'm not very good with monitors. If it's more than a cap kit or some simple soldering I'm lost.

No takers on Konami GT? Still has steering wheel, shifter, gas pedal, marquee, coin door...

Working PCB has been sold, the rest of the stuff is still available. I have added that I will include a Ms Pacman PCB cap kit with the board that resets occasionaly. I bought it from Bob Roberts a couple of months ago and never got around to putting it in.

Can I replace a U5000 chassis with a K7000 chassis? I have a U5000 monitor that is a bit messed up. The tube is fine so I was wondering if I could put a K7000 chassis on there? Is it a direct swap, ie. no changing yokes etc? If not, you'll see me starting a U5000 need troubleshooting help...

I have the following for sale, prices include shipping to lower 48. *SOLD* - Ms Pacman PCB with Daughter card and ribbon cable - working $80 - *SOLD* *SOLD* - Ms Pacman PCB with Daughter card and ribbon cable - works, except occasional reset $50 (I have a cap kit that I will include) - *SOLD*...

I've searched and can't find a definitive answer, just lots of conflicting posts. How does the security work on Golden Tee Fore? There's 3 pieces, PCB, chip, hard drive. Which parts can be swapped around?
