First i tried to fix the problem myself but i think i made it worse.
First the screen was lighting up but there was no video so i took it apart and put it back together now nothing is showing and it wont turn on.
Solutions would be great.

Re: Not turning on
Using a flashlight shine it at an angle to the screen and see if you see a computer screen showing under the beam of the flashlight. If you see a picture then the backlight or its circuit is not working. Check to see that the 4 cables going to the LCD display are plugged in all of the way. There are plugs on each of the cables with 2 wires to each plug.
However if you are not technicaaly sound i suggest you take it to qualified technician...or you might worsen the situation!

If you don't use an identical monitors, then they may not work if your video card can not handle them. The "check video cable" it means the monitor does not get a signal, and it does not mean that the monitor is a problematic monitor. You can test this monitor as a single monitor (and try to connect it using first video port, and then move it to the second video port).
It would be nice if all badcaps are bulged/leaking. Changing the lamps is a pain in the ass, i will try it myself with an 191d. But i have tried first the power supply with multimeter capable of 100kHz AC 200mV range. Better if you borrow an ESR meter capable of in circuit measurement and test all condensators.
Allways discharge, disconnect from pc, switch iMonitor on and pull wall plug, push ON button for safety. My 400V capacitor is then down to 7VDC (germany 230VAC mains). Or wait for 30 min, (i am not patient enough for that).
I have 2 Acer AL2416W monitors that i have been using for 2 years. There has been a handful of times i would turn my computer on in the morning and the screen would be black and Acer would lightly flash on the monitor 1 time. Typically a restart would take care of the problem. Last week the monitor blacked out and i can't get it to work. Any suggestions?? I switched ports on the computer to verify it wasn't the video card and tried new DVI cables to verify it wasn't those? Is this fixable??
It sounds like the Circuitry on the display is damage or cracked. I think the only solution as a perminent fix is to replace your monitor as this will only get worse. It does not sound like a back light of FL converter problem. Maybe try borrowing new leads off a friend and connect your monitor up with those to see if problem is fixed but i doubt it. Also check the pins on the lead to see if they look right.
It may also be a problem with your video card, I've already seen a problem likewise, try to remove and replug your VGA card and try again, if you can try to plug another screen on your PC and to plug your screen on another PC, then you'll be sure
have you tested the power supply connection feeds? test each connector I think you will find your power supply has failed on either the 5 volt or the 12 volt side more than likely 5 volts are down' the agp adapter needs 5 volts to run. since you have changed out every thing else I would replace that or test your dads power supply in your computer, that should do the trick
The green power light indicates that the monitor is receiving from the
computer correctly. I suspect it is going into high voltage
shutdown. There is a safety circuit that monitors the high
voltage and shuts the monitor down if it sees anything amiss. So
the monitor comes on and then shuts off. High voltage problems
are generally not worth trying to repair. Another example of a
worthless safety feature. High voltage failures are not
dangerous, and adding the safety circuit just kills the unit when it
may have some life left or worse, sometimes it is the shutdown circuit
itself which fails!
Hope this helps.
I think you have loose cabling somewhere. Try to unplug (and untangle) the video cables and then plug them all back together firmly. If this does not work and you know your machine is booting up properly, you might have damaged the monitor somehow accidentally.
