| Posted: Wed Feb 20, 2008 3:01 am Post subject: Cine 7 Question |
|
|
Hello, i found a Cine 7 that has okay R and B tubes, but the green is worn more then the rest. Are the tubes in the Cine 7 compatible with SD-187's? On the specifications on the website here it mentions p14xxx as the tube type which haven't found a reference to on google.
Thanks
Brad

These should be Toshiba t180's. Very hard to find but I think they can be rebuilt for about $300 from VDC.

No, even worse, they are the P16 tubes at $695 each.
Charlie at VDC says you can't sub the T180s for the P16s as they will wear out quickly.

That's not bad burn at all. Have you tried setting it up yet? I bet you'll hardly notice the burn..

$695 is a bit much, it's more then what i'm going to be paying for the set. For what it's worth i will probably look around for a good very low hour tube.
I didn't buy or look at the set yet. In the next two weeks or so i will. Before i give them one penny i will thoroughly look the set over to the best of my knowledge. It has over 12k hours on it, it originally belonged to a college where they sometimes forgot to turn it off when they were done using it. It was also made in June 2000, and has HD-145 lenses.

Brad, it's fine. you will NEVER (in my opinion) find a good used low hour tube. I've never seen one yet, but you could take your chances and buy some late model Cine7/708 complete sets off eBay. By the time you cover shipping though, you'll be spending more on shipping than on ordering a tube from VDC. I'll bet all will have worse wear than what you have now.
You'll get I'd say about 5000 hours of decent use out of those tubes.

Thanks, you are absolutely right. It wouldn't be worth it. I could probably just use the set until the tubes are gone, then either replace the tubes or get a better set. When it comes down to certain things, i'm very very picky.
I also received the HVPS for the 400. I'll try it this weekend. When i do get the Cine 7, i will probably sell or part out the 400. It has perfect SD-187 R and G tubes, both have excellent Focus. The blue is slightly worn, and may have a slight focus issue(although i may have mis adjusted the Astig magnets properly)
Thanks

I picked up the projector yesterday, and it was in good condition. Lenses were in great shape with lens caps.
It came with a remote but it does not work. The remote part number is R791664. It has a new battery, and i tried hardwiring it but it didn't work.
Does anyone have any ideas?
Thanks

Did you set it to 0 address?
Press that recessed button and then 0.

Hi,
I just tried setting the address on the remote to 0 and it didn't work. The Cine7 is set for 0 aswell. I tried the hardwire with a stereo connector and it didn't work. The on board controls work fine. The remote is transmitting, i checked with a camera. It is using 6 IR LEDs

Check if you find 14 pin TBA2800 ir ic in pc board near ir receiver eye.
Those fail sometimes in other Barcos, not sure if Cine7 use that as well.

Hehehe... I bought a minty PG blue for $30 once. It can happen.
But 5000 hours on that Green? I'd be chucking it in the bin, unless there was no alternative. You might be able to set it up to miss that burned in line...but..
CRTs never get the bandied 10,000 hours in my experience, a green tube (and maybe blue) is good for 3000 or so hours.

I'll have to look for that tomorrow when i get home from work.
So far the projector has a good picture, it needs some calibrating and tweaking but its working well.
There is one thing that does concern me, is that there is a weird zig zagy line at the very bottom of the crt face it seems to be on all of the tubes in the same spot and is being drawn off of the edge of the phosphor. If i put up a blank screen(black image via inputs) the zig zag line still remains. I'm going to post some photos of the tube faces to help troubleshoot the problem.
My take on the extra line is that it takes away from the quality of the image since the deflection has to draw that extra line that isn't part of the real image. Also.... Blanking does not make the line go away. The problem must be after the input boards.
Thanks

The burnt line is very very faint and isn't noticeable when viewing a movie. The R and B aren't too bad at all, but the green is the worst of the three but doesn't seem to have an effect on the image at all. I will have to post some photos of the tubes to see what model they are. I believe they are original tubes with 12k hours, most of that time was displaying black.

Line is probably drawn by ABL system and should be there.
There could be jumpers in vertical deflection board and neck boards that turn system off.

Hi thanks for your reply.
I did see a lot of jumpers throughout the set, although i don't have any documentation as to what they do. I'll have to find a service manual...
Also the IR IC is it SMT or is it a regular DIP package?
Thanks

In all my Barcos (no cine series) it is regular dip package. In 80*/120* series chip is just behind front panel sensor, I think 808 have some sheet metal cover over chip.

Well... I looked around and both IR receivers connect to the video input board. If you take a look at this photo http://curtpalme.com/images/Barco701image019.jpg the IR circuits/front IR connector are just above the input indicators.
All of the components on that board are SMT. There is a good chance that the remote is the wrong one. I also forgot to mention that RS232 works fine on the 7
Thanks for your help.

Good news, everyone!
The IR works fine on the Projector, I was given the wrong remote control for the projector. I found HEX IR commands online and i put them into a program on my Dell PDA and i pressed the button and the PJ turned on!!!!
Thanks for your help
