Does anyone know if the convergence board from a standard Marquee 9500 can be used in an Ultra chassis to temp. replace the Ultra board that is in there??
I have someone in Europe that I believe is having a problem with their Ultra convergence board (B channel is shaking horiz. and vertically). We have narrowed it down to the convergence board in that the problem follew the board when the B & G convergence wires are swapped.
To test this he has a 9500 there that he can take the convergence board from and put it in the Ultra Chassis, and if the shaking stops send me the Ultra convergence board for repair.

Thanks,

Terry

Yup, have at it. There may have been slight changes from a non Ultra to Ultra, but all I saw the differences were was plastic shields so that you can't put the convergence connectors in my one pin off to smoke them.. Wink

I might be mistaken, but putting a non ultra convergence board in the ultra projector will will result in the loss of some of the "ultra" geometry features. I was having some problems a couple of months ago with my 9500Ultra and was doing some board swaps when I saw this. But I may not be remembering this properly and it may have been the vertical board.

But for trouble shooting purposes it works fine.

Thanks guys, I suspected as much.

The vertical board used in the Ultra's is the same vertical board used in the 8110, 8500 and 9500's. You just need to make sure it has the double stack fusible resistors that's mentioned in the maintenance thread.

There's no difference in the vertical (VDM) boards..

Ok, I had some time to test this out and I was right Smile

The following features do not work with my older (non ultra) convergence and vertical boards in my 9500Ultra;

- top pin
- top keystone
- bottom pin
- bottom keystone
- horizontal bow
- vertical bow
- vertical skew

My Ultra board versions are;
- Vertical 03-263350-01P issue 11
- Convergence 03-270350-01P issue 7 there is also a sticker with 03-262350-01P so I'm not sure which is valid?

My older non ultra boards are;
- Vertical 03-263330-01P (no issue sticker)
- Convergence 03-262330-01P issue 10

I am running V8.0 software and the older boards are full functional in my 8500 so these are not faulty boards.

See pictures;

The small green wires and resistors are what gets the ultra NS geometry signals into the convergence amp.

Attached is part od schematic showing where signal is summed into amplifier.

well that is very usefull info. Basically (if i'm reading Scott's post correctly), any non Ultra Convergence board can be made into an Ultra version by simply hand soldering in the few extra components. Thumbs Up

Of course you would still need the FGM, motherboard, backplane, and V4.2U 35 chip to do a complete conversion on a non-Ultra but if you have an Ultra with a bad convergence module this is an easy fix.
