Bush portable DVD player will not load my disc

Hello
Just put in an audio CD disc or an MP3 disc, and see whether it reads them or not. If the player can read these discs, and only refuses to read DVD discs, make sure that the laser pickup unit of it is faulty, and should be replaced with same type and number. If none of them reads, there are two possibilities, the first one is of laser pickup disc itself and the second one is the strip wire [a flat flexible cable connected between laser pickup unit and the mainboard of the player] is faulty. First replace the strip wire. If it helps you, it's OK. If not replace the laser pickup unit also. The strip wire can be bought from most of the electronic spare part shops at your town. When buying laser pickup unit, its number must be noted, and exact replacement should be done. Otherwise, it won't match with the main board. OK.
