Sorry nto tell ya that something must have happened to the lcd screen or display. Has it been dropped ?? If you hold it up to a light do you see an image but no brightness as could also be a backlight problem . My advice would be to see if theres any type of warrantee on the unit cause from experience this repair PROBably is'ent gonna be cheap and I say this cause most repair centers wont even look at something like this for under 30 to 50 bucks. Good Luck

Clean the laser with a q tip and rubbing alcohol. That usually works with lasers that don't read. If this doesn't work ( be sure to let the alcohol dry and don't leave streaks) then I would either assume the laser isn't getting enough power or the laser is actually burned out.
If the DVD is connected to the TV properly using the yellow, white & red AV cable and the TV is switched to AV and there is still no picture, plug the yellow lead from the back of the DVD player into the green socket. If you see a black and white picture now the DVD output is on Progressive Scan mode. See user manual to turn off Progressive Scan mode.
Check to see if the little button that the screen closes down on (which turns off the screen and only the screen) is stuck, or jammed under the little hole that it comes up. This button is about the size of a pin on most DVD Players, and is located very close to the screen on either side.
The back light of the monitor might be defective. or the drive signal might not be getting to the screen you will need a schematic, multimeter, and an oscilloscope to troubleshoot this issue.
This is how you will have to go about this using the schematic locate the screen test points measure the voltages with the multimeter and look at the signals with the oscilloscope. this will lead to you finding the exact problem.
Your unit has a composite output. Hook a standard TV up to this connection and try it. If you have a picture your display on the portable unit is bad. Sounds like you lost the backlight. You would need to have a tech look at this to fix it. Good luck.
