|
|
This SEOS 808s has a few i2c errors...and I suspect it has something to do with Barco boards in the SEOS chassis which render certain adjustments with i2c errors. I think vpos is one of 'em...
at any rate, should I consider swapping out all boards for Barco boards, or would I hope to find the appropriate SEOS boards which would hopefully take care of the i2c errors that I'm getting on a few of the adjustments.
None of this renders me unable to put up a nice pic...but in the event that I want to fix and or replace some of the boards...should I try to find SEOS or just wait for Barco stuff?

I would look for Barco boards, to what extent was this 808s modded for SEOS, if it was setup for curved screens or other odd applications you may need the Barco boards before it will work on a flat screen.

I'm really not sure how to tell. What boards have been SEOS modded?

The real problem will be the tubes - if they have wear - that is a huge problem because of the shape of the wear .
Plus they usually have washers/spacing that makes them impossible to adjust corner focus on a flat screen.

are you sure it's not a modded focus board that makes it difficult to focus on the edges?

Everyone that I am aware of has also had to remove/reseat the tubes in the mounts to obtain corner focus.

at any rate...yes...clearly this projector is designed for a curved screen. I'm sure I will need a focus board and a few others..

how would removing and reseating help corner focus? I think I can see corner focus is off by lookin into the tubes...

AFAIK the tubes are physically angled in the housings instead of flat like normal. So you have to unsilicone and re-silicone them to correct it. Not usually worth it because they usually have some weirdass burn.

There is faint wear on the green...but since I do 2.35:1 all the time...it's a non-factor.
So re-siliconing the tubes?? Really? And what will that accomplish?

So...in summary, my tubes are probably shimmed inside the housing? Or perhaps they're not...but if they're not, they're not mounted flat like a regular projector?
Bottom line...once the tubes are seated correctly...Are the boards jigged up to act funny?

In summary..yes. And there are no physical shims, they just siliconed it at an angle.
Bottom line...not to be an ass...search! The SAME seos search turns up:

Your tubes are not shimmed, nor siliconed in at an angle, even though some SEOS are.... Trust me.
They have sheimpfluge mounts, no ? Try a bit of adjustment...
You can't put it "back to SEOS", that will render it fairly useless to you unless you have the SEOS controller(a refrigerator sized item...) and two matching projectors...

I agree...they're not shimmed. I think I ruined the astig when I took the tubes out...I'll have to start it from scratch! And I guess I can do some sheimpfluge as well...but I think I see the focus issue on the tubeface as well.
