Not sure if Curt is "on the road trip" yet or not; but if anyone has ideas or suggestions I'd appreciate it.

Here's the scenario:

While the projector was ON, there was a power loss @ my house. It happens all the time, and I've had surge protectors all my life..just for the transient surges.

But AS USUAL, power goes out, my house alarm goes off, and 4 or 5 seconds later, the power comes back on. Happens maybe 1-2 times a month when I'm home @ least.

But when I powered the projector back ON, I now get these distortions:

I thought @ first all I needed to do was a reconvergence, but it's not JUST that.

There are no error lights on...the projector is running operating as NORMAL...it's just that the distortion/double images are there....even in the on screen menus..........whether there's a signal there (like the Xbox)..or not. Do you have any idea what could be the issue, and what I can do or check?

Thanks.
Mike

did you reset the clm?

try a new recall memory.

definitely a clm issue if you ask me.

Your CLM appears to be damaged. This may not be repairable.

Surge protectors are good, but they don't really protect when you have a ground problem. if your house grounding is weak, which is usually caused from corroded or an oxidized ground rod, your electrical system could experience servere Brown-Out surges that would usually be adsorbed from a properly grounded electrical system.

The best solution to fix or eliminate this problem in the future would be to have a 10ga ground wire connected from the ground on your main panel to your metal water utility pipe. That is the quickest and most effect fix possible to cure this problem. Even the surge protection in the protector power supply would need the earth ground to properly work.

Sorry, was in town all day, catching up with an old high school buddy that I haven't seen since 1981. Good times, no work!

Do what everyone said, in the service menu, do a complete initialization, which it sounds like you already did, since when you reset the unit, the contrast resets to 30, and everything else goes to 50. If that doesn't do it, swap the CLM. If not that, then the LVPS. Then the HDM. I can't see it being anything but one of those. I can fix whatever has gone bad if you want a backup.

Hello

The backplane may be nuked, as your 8500 now thinks it is an 8000.

Get an isolation transformer to put the Marquee on.

I think the Vision machines actually identified themselves as Vision 1,2, etc. but they all default back to 8000 with a serious enough fault or if you swap the CLM enough times with many different versions. My 8500 test-machine in the shop thinks it's an 8000 but it still works just fine.
In this case I think the issue on the VIM and the only the green channel becasue R + B look fine. If it was a CLM DPB issue all 3 would be affected.
I'm going to further stick my neck out and say it's either the primary CL449 RGB amp or the secondary AD834/835 quadrupler Wink

BTW, if your power goes out that often, I'd throw a small UPS on the unit. WHile this failure shouldn't really have happened, intermittent power loss to any CPU is not a good idea.
