has anybody ever tried using a crt rather than an lcd projector?
just a thought
i know it kinda going back to the old way with the upside down tv and stuff.

but can a crt do that?
passivly direct light ?
or just have the crt in a box or something.. maybe its a crazy idea...

OK I have serious questions but I thought I'd get the obligatory first post out of the way. So why is there no www.diyvideo.com anyway? Not that I'm complaining, this site is great.

Another N00b here, but I'm a veteran of many other non-related boards, so I know how it goes with the "USE THE SEARCH! " response.

Great site, I'm sure I'll learn a lot. I didn't even know this was possible until a couple days ago. Now it looks like a fun winter project. I'm going to play around with the idea for a while.

Thanks!

Very good board.

Question: What do you guys think about possibly a CRT in place of an LCD? It would be cheaper, no?

[gwark]

thanks

answered some of my less intelligent questions

i tried crt, while it does work, it's annoying + bulky.

NVkeystone works for not having to upside down the tv/monitor.
...but... video still plays the right way up.
oh well.

crt screens look washed out - dont bother.
lcd project is a great one.

thanks

Correct me if I'm wrong, if a standalone DVD player is NOT progressive scan it is interlaced. If it is interlaced then the output frequency is 15.75 Khz if it is progressive scan it is 31.5 Khz, am I right so far ?. I want to use my standalone DVD player which is NOT progressive scan & plug it directly into my lcd monitor which apparently only accepts a 31.5 Khz signal. Therefore I need a line doubler to convert my rgb out from my DVD into a VGA signal. Is this right or am I miles off?

where I work we have a bunch of dell laptops that arent bieng used
and a couple are sitting here not working however the lcd screens work great. they are dell lattitude cpx laptops.
The monitors inside are Hitachi TX36D86VC1CAB 14.1 inch lcd screens.
I took one apart just to see the screen and tried to dismantle it.
First off I have a controller board that I bought for 180 bukcs that was tested with thisd particular model.
The first one I opened was rather easy and I am able to get to the lcd
however I broke the backlight bulb. in the process.
Is this laptop screen useless or can I build this into a projector without it. I am looking at getting all the parts to build this into a projector.
Please let me know about the backlight and any other recomendations people have towards my project.

Unfortunately both lcd screens are ruined. So you might as well just post me both them and the controller. I will dispose of them for you, free of charge...well, maybe a small charge then.

Nah just kidding.

The backlight is what is used to light the back of the lcd. It would never be powerful enough to be used in a diy projector. Your second lcd will be fine to use imho.

I am so new at this
the first one is no good without the backlight?
is there a way to put that lcs sceen into one piece and use it for diy projector? I was offered a 10.4 inch SHarp xq22 lcd for projector use in trade for a 14.1 inch screen that i have.
Should I take it? its 1024X 768 XGA I believe I could be wrong but thats what i heard him say. It is already dismantled and comes with the controller board. I am thinkning about taking that and using a fresnel and a mirror and a metal halide bulb to build my project. Thanks for all your help on this project. I appreciate it
I have learned alot so far on your site. Just need to fill in the gaps.
