I have sound but no picture on my portable DVD player.

return it, you should have a 90 day warrenty

do you get a splash screen when there is no Disc playing ( something that says something like DVD VIDEO). If not and the scren is just always black then it sounds like the backlighting circuit has failed

if the lcd screen is attached to another small printed circuit board, you may need to replace that, otherwise you may need to have to replace the lcd panel. Good Luck :)

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.

go to you`r pics and change wich pic you want.

connection between the dvd output and screen has broke link somewere. pull it apart and check it out

If you go to 1800customersupport.com it has some good info. Alco Electronics is the maker.

First check to see if there is a switch near the A/V jacks and ensure it isn't set to "in". If it is, your player is looking for an external source... Otherwise, if you mean you play a disc and get picture but no sound, then yes, the flourescet tube circuit is bad. There are no replacement parts available for that unit.

Hey, sounds like the backlight on the screen is gone, i aint sure where you could get a replacement for that model as its usually monitors i see the problem with. ie the screens is like black with very faint outline of the picture. Hope this helps John
