I think the video ground should be connected to ground or at least its own terminal since most existing harnesses will have that pin wired to the video section of the harness going to the monitor. Either way, thank you for this.

This may be helpful if you have a scope... I just connect 5 volts to the gun PCB and put the output on an oscilloscope. I shine a bright LED flashlight at the sensor, and the output will display a square wave varying in size based on how close the light is to the sensor. No square wave, no...

I consider myself very lucky. I service 4 retro arcades, and here's the list of what we have. Our first location opened in 2011. I've had only one Pokey fail since then. APB (2) Asteroids Deluxe (2) Battle Zone (1) Centipede (4) Championship Sprint (1) Crystal Castles (1) Gauntlet (2) Gauntlet...

Did you replace the starter and bulb as well? I don't see how a bad EMI filter could cause a ballast to fail. They usually just open up when they go bad.

I solved all my FR-301 problems by buying an FR-410 last year.

Anyone every see this before ? I have a spare board in the shop but before I start poking around I thought I'd ask. aykLxSpact0

Any chance of a picture ?

JST XH I believe

I have 3 Space Invaders on location that I have done this to. Original tubes were all worn out. We have 2 more with original B&W monitors that are still hanging in there.

I use a TS-80P and it's fantastic. Actually I have 2. When using a USB-C AC adapter that provides 12 volts the thing heats up in 15 seconds if not faster. I mostly use a USB-C 10000mah battery pack that provides 9 volts in USB-C. I've got a couple 12 volt rated packs but the high current draw at...

Is the flash brightness set to max in the Police Trainer settings ? Looks like a monitor issue to me.

Gotcha. Sort of like when my ears start bleeding from hearing the same song over and over with DDR Supernova 2.

It’s just a ROM swap.

Just the one song ? DIP Switch 1 on the IO board needs to be turned off then you can disable 1 or more songs.

These are the cards supported in 1.56: There are 3 different NVidia driver packages on the CD, these are the NV4_DISP.INF files from all of them.

What video card are you using ? 1.56 was the last version they released and I would think all the cards would be included in the most recent version.

I had all sorts of gfx problems. I eventually had to replace all the sockets and the ribbon connectors.

Yup. Monitor is not matching the VGA signal that comes up on the boot screen.

I wish those harnesses were available back when I was doing all those conversions.
