 I guess you make a good point.

The 6th and 7th pictures are what worry me the most. You can obviously see where the water came in and toasted the unit. The right area is a mixture of electrical burn and rust. It's only in that one place though, from what I see. I'm not sure what components went in those bays.

There's never been a stronger argument for the death penalty.

If the lenses are undamaged, they're worth quite a bit by themselves.

Lenses are in perfect shape. Just a bit dirty.

The board that got cooked... do you still have that as well, or did someone throw it out?

If it was on at the time... Can you imagine what a downer that must have been for people watching.

I bet you're right. But how do you determine which ones are good and which are bad? Are you going test them in one of your G90s? 
That one of Curt's tricks I don't understand. In testing the boards out of a non-working Barco 1200 in a working 1200, I damaged a board in the working PJ (I think it was the horizontal deflection board). It seems to me testing boards in a working PJ is risky business.

Pretty sure it was thrown out. Or left wherever they took it originally.

It's always a small risk that you take, testing bad boards in a working set. 99% of the time you don't damage any other board, but that's also why most of my test chassis have spot burned tubes.. I can take the risk since I'm repairing the stuff in the first place. Part of the cost of the repair is maintaining the test chassis.

Curt, these two missing boards are GA and GB boards which are the two main AC/DC Power Supplies. Without them, you can't use the unit  .
Unless you can't retreive them and repair GA main input board, I'm affraid that this unit must be part out

True, but at least I'd be part way there in getting a set. As Cliff said, with the power supplies being toasted, I wouldn't (if I had a G90) put any of these boards into another working G90, as who knows what problems the other boards could have suffered damage from the surges that the power supplies must have given out as they died.

Looking at those spot burned tubes makes me feel the same way as I felt looking at the youtube video of that pranged Enzo Ferrari.....sniff....

What is the 'spot burn' phenomenon exactly, and how does it come to pass?
Those vertical black lines on all tubes are spot burn?

No those are deflection burns.
That vertical line is cause when the horizontal deflection sfails and the picture collapses into a single line in the middle of the tube.
Spot burns looks slightly different.
It happens when the spot kill circuit in the projector fails which make the picture collapse into a tiny little dot when shutting the projector off.
There's also flash burns and they are similar to spot burn but looks a bit different.

Sorry Curt, but I'd also like to throw into the ring for picking up this G90 for spares. I have put more G90's than anyone else out in the field and it would be nice to have spares here for customers needing them. Plus I have a G90 to test the boards in to find out what is useable and what needs to be repaired.
Contact me if interested at terfer@comcast.net
