Does it move? Do you have more pictures of your setup? I would check all of your connections really well 😕
First thought was that you're getting a wierd light-reflection thing. Are you sure your light source isn't just reflecting wierd there?
Second thought (and one I'm more afraid of), is that you fried a color's column in your LCD panel (can that happen?).
Third thought... did you shut it off and let it cool? It might just be overheating.
Hope you fix it!

It looks like you lost connections (cable, connector problem) to the number of vertical columns. Also, possibly a blown driver chip. Check the cable marked.
I did a short term as a electronics tech for the airforce (couldnt handle the serious stundy with soo many good bars in Kingston Ontario 😉 ) but one thing they did manage to teach me was the "KISS" theory (the military loves acronyms) keep it simple stupid (the instructors weren't allways polite 🙁 ) Go for the cables first...the other thing they taught me was the best electronics techincian's look for the easiest fix first (they used to joke that a good tech was a lazy tech).

i checked that, and i can't see $hit because my eyes are not magnifying glasses.....the ribbon and cables are so small, i know something is disconnected but its hard to tell what, i want to know if there is somewhere that i can send it where someone will look at the cables and fix them or something.....aHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
can't see sh..
use the fresnel or a small magnifying glass.......
I also think in the direction of a broken or loose cable,

Is it torn? One or more conductors? In my experience, in the electronics design field, the ribbon cables are next to impossible to fix. They are custom manufactured for the job. The replacements can not be obtained. Sorry.

You can do it. You have to otherwise you got to find someone to do it or your panel is scrap.
First you got to see the problem. Borrow a late model video camera with close up focus. Get a good STRONG light. Attach a TV with video input to your camera. Set up so you can see the whole of that small flex on screen. With luck there will be enough resolution so the small cable instead of being an inch wide, become as wide as the TV screen. Then look very closely and use a tooth pick with the gentlest of movement press your cables down to the solder pads one at a time.
With luck you will find the faulty connection.
Having found it you got to fix it.
Two possibilities
(1) You have only broken a solder joint at one end or the other.
(2) You have torn the cable or torn off one or more solder pads.
If its a solder joint come loose as tested by pressing down with the toothpick you can resolder it Put some cardboard on your panel. Place a piece of thin wood on the cardboard. This is a steady rest for your soldering iron. Run your iron at a temp enought to melt 1 mm multicore in 0.5 seconds. Thats all the time you have for a resolder. Too hot an iron will melt the cable.
Watch the tv screen, position the iron just above the joint, press the cable down lightly with the toothpick and apply the iron for half to one second. No more. One higledy pigledy is a second.
There you are. Job done.
If its a broken cable you can replace as many broken ones with very thin insulated wire. Use the same length as the flex cable. You can run into trouble with new cables too long or different lenghts.
If you dont want to do it, set up anyway. Identify the problem and go and see your local electronics place and befriend a technician.
Best of luck.

easy fix...
that;s ok just run to a car parts store and get the
fix kit for rear defoggers you know the one with the thin copper wire running from left to right or from right to left (depending the car 🙂 )
them just apply the liquid stuff with a super thin brush or a pin/needle....... have fun and use a fixed magnifying glass so that you can see what you are doing.

That's why you have to love this hobby. One man's total loss is another man's "real" DIY projector (refering to the great posted fixes) 😀

Hey, you guys are freakin right, im gonna fix this god damn panel if its the last thing i do!!! 
DIY aint for the faint of heart, and i gotta thank u guys for spirring me on and giving me some great help! 
DIY aint for the faint of heart, and i gotta thank u guys for spirring me on and giving me some great help! Ok maybe a low tech fix but can't you just move your panel over since it's bigger then your overhead's projection bed?
yup! thats exactly what i did for now, as shown here at the end of this thread, 😉
