Everything is complete (wiring, box, all testing and everything else) all i have to do is fix a minor problem. Everything on my image is inverse of what the colors should be. I am getting this thread ready for when i do get finished though. The clarity with this panel is amazing. I have about a 80" screen. I can read all text for the xbox 360 in hdtv. I have to resize the pics real quick.

case was built by haphazard. Did a very creative packing and excellent job with measurement and profesionalism <<not a real word.

this is a pic of crackdown for 360.......i told you colors were messed up. its also a LOT brighter than this

It just looks like you have the blue/green component wires criss/crossed. Try switching them.

you can see in the pic they are in the right spot. I will switch them to see what happens.

Yes, but are they correct at the source? tongue.gif (Guessing you checked this a dozen times already)

so in this pic, the bubbles are the polarizer right? Carpows adhesive ones?

What im wondering is, will a pic like this exibit just how much image quality we loose when the polars arent directly adhered to the panel, simply buy looking at the bubbles?
Or am i missing somthing?

It seems like you wouldnt see the bubbles unless there is in-fact an obvious negative effect unsure.gif

If the signal source is connected and working right, then your polarisers might be oriented wrong. What I mean is that one polariser should be turned 90 degrees relative to the other. Does the panel show white or black when off? When I turn my LCD off, it shows a white screen projected on the wall.
kariya762
it shows white.
kariya762
actually i thought you meant when the panel is on does it show white or black. I just turned the bulb on (warming up as i type) and its not showing anything with the panel off. Should be warmed up by now and still nothing.....Perhaps we are on to something??? I know it can't be connections (or at least i think) not only have i reconnected realistically 12 times, it shows different colors. On the xbox dashboard where its normally orange, its blue. blue and orange on a color scale thing are opposites. The green shows purple and purple shows green. I am actually getting the tiniest show of light through the panel when it's off. It can't be the controller because vga doesn't work either. Could be xbox 360, but i plugged it into tv and it worked perfectly. I will try another system right now

I strongly believe that polar orientation is your problem. And if I were you, I would lose the adhesive polariser anyway..

This is how I'm coming to this conclusion: The LCD makes all colors with red, green and blue.

So, if your screen is supposed to be orange, that means some combination of the red and green subpixels should be 'open' and the blue should be 'closed'. But if youre polar is reversed, then the blue would be open and red/green mostly closed.

Green=red:closed,green:open,blue:closed. You are getting red and blue open, which makes purple!


BUT, you say TV works OK, and your panel MAY revert to black when powered off, although I've heard this is not common.

I hope you are able to solve your problem,
good luck.
kariya762
thank you. I agree with polarizers. hap and i already discussed replacing polars. I connected to computer and the same results. If you search google for 'negative image' the second pic should be a pic of black and white flowers. When i found the pic using the pj on my computer. The flowers were red with the stems green and the backround white. Exactly the way it should look on a normal image. Meaning that it is a negative image that we are receiving.
kariya762
HAHA YES nimhowfritz/me were both right. Me saying it was polarizers which it was. I took polarizer of and rotated 180 and same image. Then i brought polarizer close to lcd but not touching and rotated it. After i got it to 90 degree turn it made it perfectly clear. YAY! 1 problem. these polarizers are rectangles. Putting it on the way i had it won't work. It won't cover the whole screen. Someone let me know what you guys think i should do. So happy nothing is broken. Oh and next problem is fans i have broken 5 of them no matter how i wire them i turn the switch and they pop and spit out an ember and they are gone. 5 TIMES!!
kariya762
got it mounted. I tape it right behind the triplet. the only problem with that is that i had to put it out of focus to do it. I can't read small text now. That bugs me. I have to cut some holes so i can scoot the lens farther back. That will give me a little bit of a larger image too. I am so happy it works now. Thank you so much nimhowfritz and all others for input and feedback. I need to find a bright scene for my camera. Flash makes it so you can't see anything,but a sheet on the wall and since its out of focus the scenes are a lot darker. tommorow pics will come.
NinHowFritz
Quite an adventure for me too, I was anxious to see what it was.

Can't you disable your flash?

For the polariser, there are stores online where you can buy them, I would get one that is a sheet, big enough to be mounted in any orientation, so you can cut it to size while oriented the right way. I would suggest not getting a polariser with adhesive, it seems to just create those bubbles. Also mount it so there is nothing between the polar and the LCD, I think some people had problems with the fresnel or triplet messing with the polarisation and making weird color effects on the projected image.

Glad I could help!

Did you remember to wire in a 12 volt power supply to power the fans?

Tgreenwood
kariya762
no thats what i thought was happening too much power pushing the fans too hard. Im just dumb thats all. My camera just won't pick up all the light coming off of the screen. Its just really dim. PLus my camera just died.
eliwankenobi
Isn't necessary to use a pre-condenser for that bulb, which is so big??
verboten1
ever get this ironed out?
kariya762
I actually did get everything figured out. It works great now and hasn't given me any trouble. The box i have is huge though probably as big as some 15" or 17"ers. Other than that it works really well. Sometimes it seems like the colors aren't saturated enough, but i think i just need to mess with the lcd settings for that. The only thing I have to do right now is find a new way to power my fans, currently on my computers power supply.
phatcenter77
New pics?
kariya762
I also put the Precon in which made a big difference in brightness. It was really really badly fabricated. I duct taped it to a mug which went in front of the bulb then duct taped a hanger on front of it so it didn't tip over. Ya its bad. I'll get some pics tommorow i have about 4 hours of homework tonight.

pics never happened because my camera died. I took some video of me playing pac man on xbox 360. The controller doesn't accept 720p through the s video which is what im using. My dvd/surround sound thing is on the bottom of my old desk whereas the projector is at the top and I have to split the video and audio connections to get it to work and the component doesn't stretch that far. Ill put a link of the pac man thing as soon as i get it on my computer

So how did this all turn out? I'm building a 10.6" with a LL 400w MH bulb and I'd like to use a precon, but I want you to do all the work for me first, and then just tell me what I need to do.
