|
|
Hello, I have been lurking on this site for awhile and been looking for a deal on a CRT projector for quite sometime. I finally found one over thanksgiving that was somewhat near me, 365miles away, but it was a 1272 with only 2600+hours on the tubes. I won the auction at $199.00 and went down to pick it up today, the thing was damn heavy. But my wonder full wife helped me carrying it in. It had the VGA to BNC cable and the remote.

I didn't realize something though with my floor joints though.

Its not a Ibeam construction and I would probably be putting the projector rite where the two joints meet directly under the HVAC. I am kinda at a loss on how to strengthen this at the moment but I think that is because I just finished driving 10 hours.
I look forward to spending time here tweaking and tunning till I get the picture just rite and then trying to do better only to mess something up. For the price of a bulb I got a whole projector that will probably last me a really long time.
edit-I would also like to add that I have been review the instruction manual and the custom manual. I will probably pick up the DVD also.

I can't believe your abusing your new projector like that. It doesn't even have a blanket or a pillow.

Looks like you might have to reinforce your trusses before mounting the PJ. Not too hard to do but you want to spread the load out to several places. Some Unistrut might do the trick.

If you can mount close to or directly under the vertical or diagonal webs,you will be fine,to give you an idea of the floor load capabilities,you could mount the projector off one bolt directly under one vertical or horizontal web and that thing will never go anywhere.
Even if mounted the pj between the webs,it still will be fine,the timber used in constucting the longreach floortrusses is of a high stress grade,tey are designed for maximum span and minimal deflection,they're a fantastic product.

MN and I plan on using a unistrut setup. I will post my HT layout plan when I get autocad reinstalled later this week but it looks like it will be under the section where the two joints meet and not the diagnol webs.
I think I may break out my statics books and calculate the stress that the timbers will see.

As one ME to another... trust me: Leave the statics book gathering dust. In your home it'll only slow you down 
Just straddle the bottom strut elements with like material of an adequate and arbitrary length: If it's 2x4 then 'sister' 8' 2x4s to three of the existing strut elements and then go perpendicular with unistrut. The heaviest projector you'll ever hang will be in the neighborhood of 250 lbs.
--Edit: If you really feel the need to counter a direct tensile force below those butted strut nailer plates, just go vertical with some threaded rod to the top strut elements (with appropriate fasteners of course, or even right thru the unistrut and clamp the whole arrangement just below the subfloor thereby making tension in the normal direction on the bottom strut into compression in the normal direction on the top strut.  )

I think I may have run into a issue, I haven't read the sony manual yet though.
Playing around with it downstairs, I finally got a bed sheet mounted to the wall. This happened last night but I didn't pay any attention to it but with the bed sheet mounted and using my laptops vga out when I set the resolution to 8x6 the image comes in perfectly but anything above that I get distortion.
At 1024x768 the image turns into three images with offsets, the red green and blue are not matching up. Above 10x7 the image turns into static and garbled. I haven't been able to play around with the refresh rate but I will use my workstation tonight to see what I can come up with and I will post pictures.
i still have much to learn but it does make me wonder if this is a 1272 just a bit.

That just means someone had it set up for 800x600. You'll need to do a setup for whatever resolution you intend to run.
I ran mine at 1024 x 768 alot, also wide screen at 1066x600. I even pumped it up to 1440x960 but that's way too soft on one of these. 1080i looks nice and it's probably the most usefull now too.

Ok so I certainly have to read the manual then. I was figuring I would set it to 1280x720p or 1920x540P(1080i) just to play around with it.
Could you point me how to adjust the resolution on the projector?

No adjustments on the projector. It just projects whatever resolution you send to it from your source.
By the way 540P isn't 1080i. It's 540P. Not a whole lot better than 480P. It has the same bandwith/scan rate requirements but 1920 x 1080i will look better. Since you are running a PC you could even set up 1080i at 48Hz, or 1080i 72Hz or even 1080i 96Hz.
Read the manual, follow the setup. My first setup after I read the manual took me about 8 hours. Now I can get a 95% picture from scratch in 45min - an hour.
You'll set it up, tweak it. Screw up the setup, re do the setup. Tweak it. Redo it...and on it goes. Each time it will get a little better.
Also read the CRT primer. http://www.curtpalme.com/CRTPrimer.shtm It may help you out.
You have one of the easiest to set up projectors out there. Just follow the install manual step by step. http://www.curtpalme.com/docs/Sony1252_1272_Install.pdf

Just to clarify, my source was sending a 1024x768 image and I was getting a artifact. There is no setting on the projector to adjust it to 1024x768.
I just plug in the setting and off I go, just like any other video output device on the market.

Yep, that's it. You plug it in and go. No adjustments on the projector. Thats where your PC or a video line doubler or scaller come into play. The projector just displays what ever you throw at it. Just don't go nuts and try to get 1080P. That just might do some damamge running it that hard plus it can't properly display it.
What did the artifact look like at 1024x768?

That's not artifacting, that's the projector needing a setup.
Is there vertical banding in there too or was that from the camera?

No the vertical lines are the 2x4's through the see through bed sheet. The wall doesn't have sheetrock on it.
AR thanks so much for helping me with this, now that I have a rough configuration I was able to figure out that the 54x96 is probably the maximum size I want to go to.

While you can go 8 feet wide the 12xx series tend to start getting a little dim and loose the punch in the picture past 7 feet wide. I had mine set up at 8 foot wide in a totaly dark room and it was too dim at 8 feet wide. It looked better at 7.5 feet wide and better still at 7 foot wide. Plus I could turn the contrast down ( very important if you want to get some decent life out of the tubes ) to 64 from 88.
Try 7 foot wide it's a kind of sweet spot. I also had it set up at 5 feet wide for a bit but I didn't have the lens spacers to do it properly and didn't feel like doing the spring mod. BUT at 5 feet wide it was nearly as bright as a RPTV set. Eneded up with a tiny 65" 16:9 picture.
Great little projectors.
You may get an ok picture at 8 feet wide if you go with a higher gain screen. Say 1.5 gain. It will help. But with a bed sheet up like that it's less than a gain of 1 because the light can pass right through it.
Goto our Screens forum
http://www.curtpalme.com/forum/viewforum.php?f=12
and check out Willsonart laminate. It has a gain of 1.24 measured and looks great. Many of the poeple here run it.
Test with it, you be the judge try 7 feet. 7.5 feet and 8 feet and you'll see the difference. And yes all three sizes will require thier own setup. Since there's no Zoom lenses on CRT's you'll need to move the projector forward and back to make the image fit the screen.

It really depends on the particular 12xx, and even more importantly, the screen material.
I was running my old 1271 on an 8'-wide Wilsonart screen and I loved it. I thought it lacked no punch whatsoever. Would it have been brighter at 7'? Yes. Would it have been brighter still at 6'? Yes. But, I wanted an 8'-wide screen and that's what I got - and I loved it. Still do. But, it really depends on the screen material and how many hours the machine has on it. Mine was a pretty minty relatively low-hour machine.
Trying some different screen sizes in the room is a good idea if it's not too much trouble.
Also, if you set up for 8'-wide, I don't think you need to do the spring mod, as the M spacers are set up for about 96" wide. Not that the spring mod is really difficult by any means - one trip to the hardware store and half an hour and you're done.

Where are you in MN? I've been setting up
Sony projectors for years. If your out in the western
suburbs I could offer you some help.

Buffalo, my old stomping grounds growing up were plymouth (around rockford road). I can certainly use the help, I printed off the 200 or so pages of manuals. I plan on mounting the projector on my ceiling over the X-mas holidays and that brings me up to another question.
My ceilings are 9' in the basement, I looked at the PJ calc stuff and the very top of the projector to the bottom of the screen is 69" and the center of the screen is 42". I don't know what is a good height the risers should be. I am still learning and reading about stuff but I figure the two most important things are screen size and seating position. I have figured out my screen size and now I have to work on my seating.
I plan on putting a wall between those two windows and using blackout blinds over the theater side. My better half won't want to wall the window completely off. The projector is currently pointing at that corner wall.
I still have much to learn and will have to build a riser for the seating but the projector height from the ceiling is something I have wondered about and what the height of my seats will need to be.
I stopped by menards to check out prices on the wilson designer white, $89 for 60x96 I believe.
