Hi everyone,

I recently picked up a RFM and after replacing the monitor and rebuilding the flipper mechs, ive got her purring. Having an issue however where half the PF lights are out., as well as the backbox light. The PF lights out are the leftside of the Mothership board, the top right side of the upper playfield. the 3 martian lights on the right side, 1 martian light on the leftside. A couple of others as well most likely.

I replaced a lot of the globes with LEDS and it made no difference.

When I do the on-screen test report, it keeps reporting the F112 is blown. I pulled the fuse out to test it and it tested fine. Replaced it anyway and no improvement and the test report keeps suggesting its blown. The test report is also reporting

F112 Fuse is blown (T5A)

This is my first Pinball 2000 machine, and my first "modern" style game, so very unfamiliar with this setup with so many lamp issues reported, not sure where to start?

The fact its saying that the fuse is blown, when its not - does that suggest its a board issue?

I removed J106 and it stopped some of the working lamps working, however it did nothing against the fuse being seen as blown issue

LEDs will give you lamp errors as they do not give enough electrical resistance to tell the machine there is a bulb there. They will work and the game will play fine with them though.

Not sure about the fuse.

Bring this over to the RFM club...you'll get more assistance...

Thanks but I don't think that will be it as the globes actually don't work in the game
