Congratulations. And to think you were going to throw it away and it was just a couple fuses.

AMPRO 3600 ALIVE AND KICKING !!! Thanks for helping me out. Sometime soon, I'll do a comparison with a Marquee 9500LC ULTRA. I found a chassis, just need to dig into the tube pile, and start puting one together for you. Good to hear you got the 3600 sorted out. |

Ups, I was a bit ahead of myselves. Impossible to get it aligned. Lots of weird thing going on:-) Looses sync, no room for turning the red tube. And some wild bending and distorting the raster. Maybe it all was to good to be true:-)

Could you post a pic of the internals of this machine? (how are the tubes and boards align etc.)
Have you tried resetting (zeroing to midpoint) all the elctronic adjustments yet?

Will try posting pictures tomorrow. The sync goes on and of in
60-120 sec intervals. At one time conv-controls affect
The setup, next moment it wont. And then back again.
Just like I remember Ampro:-)

It is just a myth AmPros are problematic. I've seen projectors from every brand to produce hopeless, funky problems.. Once these problems are sorted out it can be a nice machine, I'm sure. Although I never had an AmPro I always wanted one...

Havent checked the battery, will definetly do. But I'd
Be surprised if that caused any of those problems.
Its a sync/scan thing, but I'll admit all my settings are maxed
Out due to a poor align setup:)

    I dont know if this makes any sense, but you should be able to see a scan fault across the screen, plus some distortion in the top of the screen. It is absent in 'help' or 'test' mode. But even there the picture shifts a 'click' down, and reverse it selves within a minute or two. In the one stage, it cant be altered with setupcommands.  |

Do a code 55 and see if that changes.

Well it means that something in registration is causing the problem. Usually it is 1 or more settings being way off or at extremes. When doing a setup there are parts where registration is turned off and on in order to do a proper alignment. You really should neutral out all settings in both registration on and off and start from scratch. If you look in the service manual when doing the setup procedure it tells you which adjustments are made with registration on and off. But everything needs to be neutral before any attempt to do a setup and start with a clean channel.
Also make sure ACS is turned off.
