My Audiovox D1788 says "no
Hello
Your Audiovox's Laser Picup Unit is in trouble. In payers, that can play both CDs and DVDs, there are different laser Beams from the same Laser Picup Unit, one have with a wavelength slightly differ to the other. When we insert a CD or DVD disc in to the player, at first the control system inside the players' circuit board will detect it, whether it is a CD, MP3 or 'DVD, by variying the wavelengths of the laser beam, and confirm it to be a CD, MP3 or DVD. Only after this detecting process, it will read its lead-in track and start to play.
In your CD player, now there is only beam that has the wavelength to play DVDs. Others are not working. That is why, it plays only DVDs and not others.
But before replacing the Laser Pick up Unit, you just replace its strip wire. Strip wire is one which connects the Laser Pickup Unit ot the mainboard. It has carbon conductors, instead of metal conductors. There is a chance to get a break in these conductors, even one of them break, will cause a problem,. As it has to move along with the laser pickup unit, when tracks the CD, the chance for a break is there. Just replace it first and see will it help you. It has clips on both ends, and after releasing the clip, it can be replaced easly. If this does not help, replace the Laser Pickup Unit, with same type and number. Insist on same type and number, as it is a critical component in your system. OK.
