Hi everyone, I really hope someone can help me out here..... My skill level: hobbyist. I've always been into electronic repair, and have tackled simple to medium (cellphone lcd repair, smd soldering) type things...ANYWAY...
I have a popular car stereo/gps unit (vr3 vrvd640g). It had a dent in the top of it and a cd was jammed in the disc drive mechanism. I have reseated all of the physical mechanisms and have restored everything to a normal state.
issue: the motor that pulls the disc into the unit once the disc is sensed is not working/triggering. Additionally, the unit will not read from sd cards or usb drives as it should(it recognizes the sd card, but no menu will come up and play controls do not work). Since the dvd player controls the usb and sd menus, I'm guessing it's related.
nothing "looks" fried or faulty. The soldering work in this unit is pretty poor and sloppy overall. To complicate matters, the ribbon cable that connects the disc module to the mainboard is captive and is only detachable by desoldering.
Other than the dvd and removable media functions, the unit powers up, gps works and the radio work. Just no dvd/cd or removable media support.
The IR LEDs *do* detect when a disc comes between them, but again, the motor does not engage to pull the disc in. ANY help or starting points from here would be greatly appreciated!!!!
