I bought a Sony VPH-1270Q which I'm planning to set up using an 80" curved screen. I've got most of the setup figured out, but I can't seem to adjust the horizontal and vertical size in video mode. The size adjustments available when you hold down 'test' only affect RGB mode. The 'RGB size' button also only works in RGB mode. Right now the picture is roughly square and needs less vertical size, or more width. I've downloaded the user's manual, but it only covers basic operation.


What do people think of the PC-1271 switcher and IFB-3000 line doubler? It looks like the IFB-3000 has 3 S/composite inputs and a single component input. Will the component input work with a DVD player? Is there a component input card that's HDTV compatible?


What do people do about the fan noise. I need to floor mount it resulting in the projector being very close to the viewing location. Are there any quieter fans that can be installed? What about enclosures which block the noise while allowing adequate ventilation?


Finally, does this projector allow you to store different size settings for easy switching between 4:3 and 16:9?

Hi

1 do you have the installation manual you can get it on the net

search for crt cinema


very good site for 1270 mooneyass.com


2 switcher is good the ifb 3000 is not the best line doubler but handy as it fits in to the switcher

component I think you mean composite use a BNC to RCA cable

search “Understanding video signalsâ€

2A the best connection for HDT would be the 5 BNC inputs IFB 10 or 11

But you would need a DVD player with 15 pin out

search for ifb12 to check other options but they wont function on the 1270



3 search for “fan mod†you will find a couple of options

3A search for hush box


4 yes

you really should read the operators and installation manual

search for 1270 I think 16:9 has some issues on the 1270

"I think 16:9 has some issues on the 1270"


If you find you can't achieve the 16:9 ratio because you can't shrink the vertical enough or open the horizontal enough,... I can help.


There is a adjustable pot RV104 that lets you open up the horizontal rasters and adjusting this will make 16:9 possible if it's not already.


Anyway, we can burn this bridge when you come to it.

Could you please go through your procedure

I didn't you could do it

Thanks for the link. That answers most of my questions. I had found the owner's manual, but nothing covering installation. It's hard to find all the hidden key presses by guessing.


The IFB-3000 looks like it has 4 inputs. 3 are S-video and composite and one is component (labeled Y, R-Y and B-Y). I want to know if the component input is compatible with the output of a DVD player.


I've read that the IFB12 is not compatible with the 1270, but it should work in a PC-1271, or 1272 switcher. Would this allow me to input HD component? I would prefer to use RGB for everything, but finding RGB DVD and HDTV equipment is difficult at best. There's no broadcast HDTV in my area and I'm pretty sure the HD cable boxes only output component and DVI HD. What about dish network satellite boxes? Do they have an RGB out?


I'm looking for the cheapest way to:


1. Convert NTSC and PAL sources to progressive

2. Display DVDs in progressive (line doubler, or pregressive component out)

3. Display HDTV from a component source (this can wait, but I want it to be easy to add in the future)


If anyone knows of an affordable RGB prgressive DVD I'd love to hear about it. I bought a cheap one with RGB out, but there's a bug that stops it from outputting any sync in prgressive RGB mode. Progressive component works fine, but I currently have no way to display it.

The ifb12 is definitely compatable with the 1270.

I use an IFB12 to display component output from a progressive scan DVD player on my 1271. If you have an IFB12, you can try my settings.


That's not likely to help you with the HD stuff though. I don't know much about HD but I do know that several providers of HD to have RGBVH as an option.

Halo,


Yeah, I'll write up all the info but... I can't take mine apart just now. (I have to take it apart to remember where RV104 was exactly.)


I do think that if you take off the main cover (sometimes called the hood) that you can spot it if you trace back from the focus adjustments past 5 big inductors (?).) Anyway,.. the 12xx doesn't let you use the full horizontal raster and some people overcome this by modifying porch settings with a HTPC but you can also tweak RV104 to open up the horizontal rasters. Of course this adjustment if done too far could lead to the ability to set up the rasters to go beyond the tube face and that could lead to disaster. The user in this case needs to pay attention to make the largest horizontal raster size big enough without being too big.

Have a look at the Momitsu DVD player

[Halo1963]

Any of the 12XX installation manuals would give you the idea

You need the PC 1271 switcher for the power requirements of the IFB 3000

Don't use the PC 1270 switcher

Did you see this whole thread?

I prefer using a standalone video processor and not using the progressive output of a low-end DVD player. Just run the s-video from the DVD player and let the video processor de-interlace it. The picture turns out better quality and is brighter, than if you run the component output of the DVD player to the vid processor. My processor does a much better job at deinterlacing than my DVD player's circuitry, because that is the primary function of the vid processor. Low end DVD players just have progressive ability as a marketing 'hitch' in my opinion because the quality of the 480p it produces is marginal at best.
