Hello to all,

I am having a problem and do not know where to turn. I have a BD808 hooked to a Pioneer DV-C36 and a DCT-100, via an Extron DDS 402. When I turn either the dvd or stb, the extron shows the H/V freq for the selected source. The dvd is going to the bnc in and is set to YUVp. The stb is going to the rgb input. The problem is when I turn on my projo, there is a warning that says input not availabe or something to that matter. I have the output of the extron set to BNC out and the inputs going to port 4/5 on the barco. Am I doing something wrong? The Extron has selectable outputs and i heard that 1080i is the best resolution for the BD808, but there is also a section for Pos/Neg sync on the extron that I know nothing about. Since the dvd is component only, I am assuming that the H/V sync coming out of the extron is not necessary, but what about the rgb? I really want the experience of setting this up myself, but man I wish there was a crt for dummies book out there. This is my first set up so I am not changing any components unless it is imperative for the operation to work. I don't have the projector hung as of yet since I am recovering from a knee injury and it is only me and my wife doing this project. I am hoping it is just some error I am making when I am selecting my sources. I am a newbie, so please don't flame me for my ignorance. I just want to resolve this issue. I bought the BD808 for only $175, but was not able to see an image on it since the original owner had it in storage(silly me). I see that when it boots up it says that is has only 2792 hours on it. Hope I didn't get dooped. Anyway falling off the subject. Any help would be greatly appreciated. I see that there are a lot of people here who know what they are talking about so I hope someone hears my cry.

Thanks in advance.

Set output to negative sync. The BD 808 uses negative sync only on port 4/5.

Try and get one of the internal patterns to display from the scaler.

You need RGBHV from the extron to RGBHV of the 808

On the input side use the top 3 BNC inputs. RY,Y,BY (You will have to change a setting in the menu of the extron to component input)

Well I did whet you guys said and.....Nothing?!?! I set the extron sync output to negative for both Hor/Vert on port 4/5 and I still get that source not available message on the green tube. I was getting colors out of the blue and red tubes at first, but now I have no color at all? Hmmm, I tried to get the cross hatch pattern to show, but nothing came on. I have the scaler set to 1080i@50hz....and have tried other settings as well..but nothing. I am new as I have said before, but shouldn't there be a start up menu or somehting when I turn on the unit or something?

The manual says I should get a start up screen that displays a white screen letting me know of how many warm up minutes I have left, but I have never seen this.... I am getting frustrated and think that I have a bad unit. I double checked my cables for contunuity and they all check fine. The number five input says that it is for RGBHV with the composite sync on the H/V. When I press 5 on the keypad of the BD, I get a noise as if it is changing to this input, and then I get that stupid message.

Do I need that controller the RVD of something like that in order for this to work or is the extron fine and I; being that super smart kinda guy (NOT EVEN 1/4 TRUE) just making a mistake. The extron is letting me know that each source is coming to the unit...uh oh holdup a sec......okay I must have done something right because Star Wars just came on. I pressed the enter button and presto....Okay wish the tubes didn't come on cause @!@#$%& the picutre looks like shoobydookaka! Okay I uess the fun starts.

Um I have another question....The red tube seems less brighter than the blue and green...is this an indication of a soon to be replacement? Would pictures help you decide? I also looked into the tubes while they are playing. Is this a bad idea? The blue looks very clean and smooth, the green looks good, but a little fuzzy, and the red looks digitized for some reason. Are these problems ( Green/Red) easy to resolve during calibration (Needs it bad) Star Wars looked like tossed salad.

Thank you Tom and Barcoguy for getting me this far, I know I have a long way to go, but you guys have made my day thus far!!!

take off your lens get a light in front of the tubes. Take some pictures. post them. Everyone will let you know if your tubes are good or bad.

Or just shine a flashlight through the lens and look for a brown burned spot on the white tube face.

If this is your first CRT start out with something simple. Get a VCR or standard DVD hook it up follow this......(below) Use composite (yellow) into the video in. It will look VERY BAD. but its easy to learn what the heck everyone on here is talking about if you don't have to learn/mess with your scaler as you do your first setup.

Okay just got off of work...late night too!!!

Barcoguy, I did what you said by shining a light into the lense, and to my eyes I couldn't see any burn in on either of the tubes. They all looked pretty white to me. I know my convergence is off, so should I do this before I hang the projector or afterwards? I am a little hesitant about taking the lenses off as I don't want to tdamage anything. But I assume that one day I may have to for some reason or another. Yes I ran the dvd player with composite and you wre right it looked like crap! I appreciate you getting me this far.

OK if you are totally new to CRT there is too much information to type it all out. I suggest you buy
http://www.curtpalme.com/forum/viewtopic.php?t=4346

It is a lot of bang for the buck.

Once you get it download the barco data manual install manual.

You have a nice projector if your tubes are white.

The trick on the data is to put thin washers on the lens to get proper corner focus. But you will not know what any of this means.

Trust me I learned the HARD WAY years of playing around. Buy the DVD it makes life easier you will get a better install.

Do not worry about the convergence that is the very VERY last thing. It will just sort of fall into place with a properly physically setup unit.

Once you have followed along with the dvd you will know more. Come back ask questions everyone here is nice and willing to help.

I would also not mount it until you watch the DVD

If you want to play around with it just get it level and square to the screen. Then go through the installation manual.

You should be able to find the setup manual here.

http://www.avforums.com/forums/forumdisplay.php?f=72

The lenses are only held in place by 4 easily removed and easily replaced bolts.
Remove them and post a photo of the tubes. Also it will aid you in maximizing the rasters.

I removed the lenses today and this is what I found:

I noticed the greeb tube does have some wear on it, but i hope not enough to prolong the setup. Man I downloaded the user and install manual for the bd808...fwhew...guess I got to get that dvd you suggested. Can I start to do somethings while I am waiting, or should I wait for the dvd?

You got one HECK OF A DEAL!!!!!! Those are NICE TUBES!

Order the DVD it takes a while.

You can start reading through the install manual.

No Blu Ray/HD DVD sources, only off air stb. I am waiting for a player that has 7.1 analog output for DTS Master HD/True Dolby since my receiver only has 7.1 inputs, no HDMI. I have a basic prog scan player (DV-C36). I know that I'll only be scaling up SD for dvd playback, but I shouldn't have to scale the off air though right? I will try to fix the g2 that you have talked about.....as soon as I find how to in the manual. I am glad that all of you feel as though I got a good deal, makes me feel better about the purchase.

If I am doing 720p, what Hz should I set my extron to?....It allows for 50, 60, and something called lock. I also read that if your change the way your projector is to be mounted, that the geometry and convergence needs to be redone. Right now the 808 was set up to do front proj-table top. I want to hang it, so should I flip the dang thing over and then start tweaking it, or should I tweak it now, hang it, and then tweak it again(lot of work)? I will be officially working on it tonight since I finally have an actual chance to do so.....being in the military steals alot of time from you. Thanks in advance for any suggestions.

By the way, if I do decide on a BD, which one do you recommend for quality playback? I have not actually looked into any players since they hit the market. It's been this for me for the last 5 years.

I am going to build an HTPC and use one of these GGC-H20L Combo drives. So I can buy cheap HD-DVDs and play BLU

Well I finally got a chance to fiddle (literally) with the 808 and I really feel like a 3 year old whose taking quantum physics!!! I took the lenses off to adjust the raster, but should I put them back on to adjust everything else because if not, I am going to have to get some glasses to fine tune this thing. i hot a headache just looking at the manual. Is there anyone in the Colorado area (Colorado Springs/Fountain) who'd be willing to assist me in my quest to get this thing fixed? By the way, the red tube was way left when I got into the adjustment menu.
