The problem was probably completely unrelated to a component failure on the PA... either temp related where a good cool down during the remove and replace helped when you powered back up, or you had a loose board connection... those subs of yours might've rattled something loose.
You could've swapped the PA from the other half of your stack, just to figure out if the failure follows the board.
Hmmm, if Curt and his squeeze are already planning a trip, let's pick a date and Wallace and I will plan our road trip.

I'm thinking it was one of the connectors on the PA board. This has happened on both projectors..........
Either way, I'm HAPPY AS HELL it's back up!!!!!!!!!
Let's pick a date big dog! What's good for you guys? Wanna do August again?

Glad to hear the G90 is back up & running.
That's a great looking hushbox you guys built. The only thing I could add is to paint the lens area flat-black to cut down on reflected light from bouncing around in that immediate area of the room. It's not much light of course though, so maybe it won't do much.

Thanks big dog.
I actually had Arli take off the part over the lens. We are going to recut some more wood and have that panel recess behind the lenses.
This way no light bouncing issues.
I'm also going to have to vent the top of the front so that the G90's are pulling in air from the room.
There is no way I'm going to be able to seal that hushbox unless I force cool air into it instead of pulling hot air out.
I'm confused.........

Isn't that crazy that it worked in Arli's? I had two G90s here, both functional. I took a flier on a third off Ebay and got burned on the one that showed up with deflection burn in all three tubes and the patented YA shut down error codes. I removed that YA board and put it into the known working G90 and it then resulted with YA shutdown error codes. I then put the YA board from the working G90 into the faulty one with the deflection burnt tubes. It ran fine with no problems so I figured it had to be the YA board. Swapped everything back and had the original results with one working and the deflection burnt unit not again. Sent the faulty G90 to MP for modding research and he in turn sent my YA board to Curt for fault finding. Guess what??? When Curt received that YA board, he threw it in his test chasis and it ran fine for over 72 hours on four different occassions!! WTF?!!!!! My next step is to have that YA board and the PA board sent down to Terry since he has worked on a G90 exhibiting almost the same problem. It may be better to just have the whole PJ shipped to him since it might not be either board. That would cut MPs research short, but I'm sure he'd like to get my headache out of his shop with how busy he is.
On a side note, John has completed the custom length extender cards and shipping them to Terry and Curt at the moment so board level testing should be a little bit easier to troubleshoot.

Nah. Not crazy at all. Me thinks I had a corroded connector causing the issue. I've been having it with both projectors from day one in extreme temperature changes.
Weird huh?
So, HOW WAS THE RS1?????????????????????????????????????

Cliff,
As you know the airflow on the G90's is in the front, out the back. If you are running a hush box, the PJ will get might hot unless you vent the air from the rear which it sounde like you did.
I run one of these duct stats http://www.smarthome.com/3018/DuctStat-Automatic-Duct-FanThermostat-DS100/p.aspx on the rear ceiling of my hush box tied to the exhaust fans. That way the fans come on when the hush box starts to warm up and continue to run (even after the PJ is off) to exhaust all the hot are.

Terry,
I bought one when we added the extra 6" exhaust on top of the two 4" exhausts I have in there now. I removed the board from the front that was making the box look "nice" because I think the G90's were just pulling in hot air that was rising to the ceiling inside the hush box.
My exhausts are behind the projectors but I do not think it's enough when the intake is restricted to warm air in the front of the projectors.
I ran the 6" with two 500CFM duct fans into my computer room next to the theater and it is heating my whole basement.
G90's produce a lot of heat for sure.

The spec sheet says the G90U pumps out over 3500 BTU of heat. You've got a 7000 BTU heater in your HT. I dunno exactly how to translate that into something more understandable, but a 7000 BTU air conditioner is supposed to be good for cooling a 350 sq ft room. So I imagine a 7000 BTU heater would do a pretty good job on 350 sq ft or more of basement. Your basement is a lot bigger than that but I'm sure the G90's help!!
