Question about TruTech LMD-5702RT Portable DVD Player
Did you also test music cd (normal WMA file).
you did? and still no disc.... go to step 3
1- the laser can be bad. If you open the system and locate the laser, check at the back of the laser block for adjustment screws. one is for cd and the other is for dvd reading. adjust one at a time counter- or clock wise the screw with small portion. always test after do this adjustment since you dont use a multi-meter to watch the voltage (between 2.99 and 4.95 volts). sometimes you only have one screw, so that is the only adjustment screw then for both cd and dvd.
2 before adjusting the screw be sure it does only play cd WMA file. If for some reason none of the cd/dvd plays dont ever touch the screws.
3 listen for a high pitch sound coming from the servo motor when the player is reading. does this sound comes on short and then start all over again? this indicate that the motor can not reach its rpm for reading the disc. if your lucky, try e-bay or amazon or an electronic shop for a replacement. any servo motor will do, even if its another brand as long it has the same dimensions.
did you use the player very often if I may ask? How much often (2, 3, 4 dvd's at a time)....
