DVDs are not playing. when
Hello
Your Sony DVD player has problem with either it laser pickup unit of with the strip wire connected from it to the main circuit board. You just replace the strip wire, which is flat cable connected from the laser picup unit, which has carbon tracks as conductors, and are easy to break. As this strio wire has to move along with the laser assembley, there is chance for the conductors to got break. This wire is locked at both ends with a sort of clip, that you can detect and loose it to detach. First replace this wore. Detach it from your player, and go with it as sample. Note the ends of it, some may be single sided, and the othere may be opposite sided. Before etaching the strip from player, make a marking at it end side, which have a blue end hardner attacted to it, so that when you replace it, you can make sure of its side.
If this does not help, there is no other way than replacing the Laser Picup Unit itsef. When replacing it, it is best for you to buy it as a whole assembly, which contains two motor too and will not cost too much more.
OK.
