I found these service manuals on the internet for 7$ apiece.
however I'm kinda cofused as to witch on I need.
Can anyone tell me if there would be a difference between the different types?
Barco Data 701 * RD 701s OEM 42", 50", 67", 100" * SERVICE Manual
Barco Data 701s SERVICE Manual
Barco Vision 701s * BV 701s HQ * SERVICE Manual
I see the Vision and the Data are different. I have the Data grade.

I purchased the whole deal when I first got my Marquee a couple years back. I think I paid somewhere ~$10. I learned they aren't all created equal tho. The service manual was a piece of $hit. It wasn't a service manual that's for sure.
Those are older sets aren't they?....aren't they posted here? I have a Barco 800 (non graphics) that was given to me that's sitting in the garage (for over a year now) so don't know much about them. I'll bop over to the main site and see if there's one posted (just for giggles).
My advice tho is to be careful what you buy as it might not be as advertised.

No service manuals there. Although OP wants the service manual, for all things but the service manual, this is a better link:

It is possible the service manual will not be of any use to you, as Curt has said they often contain very technical information and circuit diagrams that won't really help you fix your projector.

Not to be a smart ass, but if Curt believed that, the service manuals would be posted. Why should I care about giving you information you can't use?
I've never used service manuals to diagnose or fix a problem, yet I've found them helpful for a general understanding of things.
As I've said before and don't want to force this to degenerate, there is no way Curt would loose business if he posted the manuals. In fact, I think he would gain business by:
1) Driving traffic to the site, and
2) More repair work
About number 2. A service manual would give people a false sense of confidence. "Sure I'll buy that CRT, I can get the service manual to fix whatever goes wrong" (sale of CRT), followed by a glance at the service menu when they have a problem, "Oh sh*t, there is not way I can fix this, calling Curt..."
At the end of the day, how much more repair work would an auto repair place get if all Haynes and Chilton manuals were taken off the market? Pretty much no more.

From what I can see, the Service Manuals have to be bought. The Installation and Owners manuals are free.

The service manual will help me track down any and all bad parts. Reading a schematic is pretty easy, well, for me anyway.

I bought the manual for 7$ and downloaded it. It's 565 pages of info. If I cant fix it with that, I need a new hobby

Actually what would happen more often is curt would be plagued with more boards that someone had already "tried to fix". Those are the worst kind, and usually belong in the recycling bin. A false sense of confidence in someone with zero electronics background is just a bigger problem waiting to happen.

Only knowing how to read a schematic doesn't show you were the bad parts are. Knowing how all the parts work and how to test areas sequentually to pinpoint the problem is the knowledge that is needed and service manuals don't do this.

That doesn't make any sense. Someone with zero electronics background is going to look at the schematics and say "I have no idea what this means". A service manual doesn't show you how to troubleshoot down to the component level. Some however do show you how to troubleshoot down to the board level. After that you have to know how to read a schematic.

Well, Curt already had my convergence board for repairs, I paid 200$ and waited a month only to find out that when I connected it back up, It had the same issue. I already talked with him about this and he had me do some troubleshooting only to find that it was the convergence board, so although I really respect Curt and am thankful for all his hard work. I swapped the board out with another one, someone on this forum has done the exact same thing with his 701s and had the exact same issue as I have now, so he replaced a fuse and now his works great. So instead of digging around blindly marking all the fuses in this thing I thought it might be a good thing to locate them with the schematic and take a more professional approach. I sure as ***&%$ dont plan on giong into buiseness repairing CRTs.
So anyway the service manual tells me what type of power I need for the board, so that's the first thing I'll check. It seems to make sense that if I get the correct voltages from the supply, then I need to investigate elsware

well we can argue about what a person trying to repair their own CRT might or might not do but I don't really care to be honest. the only CRT I like workign on is the maruquee and i have all the factory service manuals for it. Also, most of the other machines have service manuals floating around on the internet, either hard copy's or donwloads, so it's not like they're hard to find. I don't know why Dave broguht up the issue of hosting them here, if it was my site I woudn't waste band-width on it.

I already responded to you that the convergence fuses are F10 and F11 on the power supply board. If you want the two convergence boards checked, I have a 701S test chassis here, you can PM me.

yeah that's really cool, we're specially trained to do that here. 
I wouldn't put too much effort into fixing the 701, I've seen working ones selling for around a 100 bucks. troubleshooting at the board level isn't really worth it at that point. If you need a board check with front range. Seems like he has some listed on flea bay.

If I had a board that Curt repaired and I put it in a machine and it did the same thing, knowing Curt, I would be looking for what was screwing up the board. It's a good idea to have a service manual for all your stuff.
Just and old man's opinion.
