SONY DVD player No power. Seems common across many Sony DVD's
Has anyone else clued into this one?
Im seeing Alot of DEAD Sony DVD players all of a sudden. and of course i have not 1 schematic on any of them. im very suspecious of those crappy little Surface Mount Caps. But it seems like the power supplies are OK. Only other thing i can think of is CPU reset is dead. Just wanted to know if anyone else is seeing this as well. |

Im seeing Alot of DEAD Sony DVD players all of a sudden. What kind of dead? Dead as in it won't read a disc or dead as in it's not working at all? Second, model numbers? - Reinhart |

Almost Compleatly Dead, No display of any sort.
little red light goes to green for a few seconds, then goes back to red. Model in particular is DVP-CX860 but also happening in DVP-C650D "LASERandDVDfan" wrote in message ...

This usually means a mechanical jam, or a drive problem involving the sled
motor - it can't home the pickup during initialization, so it shuts back down. Mark Z. "Techie" wrote in message t...

No..Actually the Flourescent display is Dark and not lighting up. Ive done some digging, there is the 5 volt running throught things and i have high frequency at the crystal next to the micro. i can get the LED to go green for about 3 seconds if i press on the eject button, but the motors do not attempt to turn at all. I looked real closly at the display in the dark and hit the eject button and i see the filliments light up very silghtly for the 3 seconds. Also saw some segments of the display trying to light up. This thing has those surface mount electrolytics on it, so I am going to replace them and see what happens. Does anyone have a schematic on this they can post? B.T.W.---How come i never see anybody posting schematics or software in here? "LASERandDVDfan" wrote in message ...

If memory serves me the CX prefix before the numbers indicates that the player is a carosel megachanger. Ive done some digging, there is the 5 volt running throught things and i have high frequency at the crystal next to the micro. i can get the LED to go green for about 3 seconds if i press on the eject button, but the motors do not attempt to turn at all. I looked real closly at the display in the dark and hit the eject button and i see the filliments light up very silghtly for the 3 seconds. Also saw some segments of the display trying to light up. It could be in the power supply. Wish I could be of more help. Have you tried a Google search to see if there has been a similar incidence of this problem with other Sony DVD players and a possible resolution? Good luck. - Reinhart |

You need to fix the motor drive problem. Might be impossible without the
service manual however. The presence / non-presence of motor B+, whether it's 7, 10, 12 volts or whatever, and the drive signal from some incredibly complex IC. Could be a mechanical hang-up in the feed motor - it's usually replaced as a complete ass'y with the pickup. Try manually moving the pickup to it's "home" inside position and see if the power stays on. Mark Z. "Techie" wrote in message et...
