I've got a "classic" Marantz VP12-S2 PJ, and it went dead the other day in the middle of a movie and turned the "Warning/Lamp" light on solid. Normally, this is the signal to replace the bulb, but the bulb had been recently replaced, so I was suspicious. I ordered a new bulb anyway, but when I installed it the problem still existed. The PJ powers up, I can hear the fans, I can hear the color wheel spin up, and then a few seconds later it shuts down and the red warning lights turns on solid again.

I've tried all the tricks I could find online - unplugging all sources, bending the contact switch on the bulb door, unplugging and re-plugging repeatedly... nothing works.

The only other thing I can think of now is that it's the ballast not being able to provide enough power to turn on the bulb (on one try, the light came on for a split second, and then died).

I'd like to try and replace the ballast myself. Google was no help in finding a part number... anyone here have any leads for me (or perhaps another idea of something to try)?

Thanks in advance,

Did you try contacting Marantz for the part. The parts departments phone number is (201) 762-6392. I just ordered a power supply from them for a VP11S1. You can order a service manual for your projector here

I had the exact same problem about 5 months ago and tried all the tricks you mentioned, but nothing worked. I finally took it to an authorized Marantz service (about 3 days later) and all of sudden the projector started working. Well, it's 5 months later and I just hit the problem again last night!

Did the Ballast replacement work?

Thanks in advance,
