Well, it did it again.
I re-seated the cables and even opened those damn molex connectors and crimped them a little tighter.
It's being stubborn. It works great when it feels like it.
I am officially tired. Anyone in LA want to buy a modified Runco 990, AKA black PG10 with an extra green and blue tube? I just want something that works when I want to use it at this point. I do not want to take this whole damn thing apart AGAIN to chase down some solder connection, or whatever this is.
I'm just going to bite the bullet and buy a digital, stick it to the ceiling and watch it until it breaks and then buy another one.
Really, I am at a point in my life where fixing everything "I" want to use is getting on my last nerve. I am just so done.
Frustrated doesn't even begin to describe me right now.

Sorry to hear that but I'm right there with ya. I'm taking a long weekend and redoing my rack and automation programming to make the full switch to digital. I can't believe how much space I'll free up in the rack and how much wiring I'll be able to eliminate. Not to mention all the work arounds we have to make these old beasties work in the digital age. I hate to think about how much money was spent making CRT work. Kick it out to the curb. That's what I say  The nicely modded 4600HD will stay on the ceiling until the tubes are toast (not long to go) as I save for a new giant LED flatscreen. It will be ready to make the swap when the time comes. All I'll have to do is upload the new program to my Crestron processor and swap the hardware.

It is infuriating!
Turned it on and off a few times and when it comes up it runs fine. Ran Avatar while I made some fine adjustments.
Turned it off. Will see what it does the next time.
It's also not a loose connection.... wiggled, tapped and re-seated everything.
The Image is astounding, but I'm shopping around for a new projector anyway. I can't screw around with this behemoth once it's on the ceiling. It either works reliably or it's gone.
There is nothing left to replace......

Just solder a wire to the + side of C5501 on the HV board and connect it to your DMM and see if it's no +110v every time you have no picture. If your loosing the +110 then just connect another wire to the +110v output on the P/S and wire nut it to this wire and be done with it. No need to go hunting.

Been thinking just that.

Well, the story continues.....
The HV problem has been solved and I ended up replacing a BUNCH of capacitors. They measured fine with an ESR meter, but were physically leaking. My first clue was the odd smell. In the end.... use experience and replace caps that are known to go bad on a given set.
The Video out board, once again. I had to do this on my original PG9+ as well. Did the calibration again and the picture is back to it's usual glory.
The biggest problem I have now.... Fan noise. Time to quiet those down.
So far so good. Crossing fingers, but I think I got it.
What a PITA! (But fixable!)
