Help!  I have a tower 5 disk changer - the SAVA D900.  There are two DVDs stuck in there and the system turns on and reads DVD but the changer won't move.  Not a peep of movement.  I took the speaker off the top and unscrewed the electronic face plate.  I can flip open the white cover that the DVDs are behind but can't see any DVDs to jiggle or grab to unstick it.  How do I open this further to get to the disk trays????  Without totally ruining the electronics, etc???

Hello all,

My girlfriends DAV-C700 had this same problem.  I applied the modified fix using the Q002 assembly and the 1k resistor soldered in parallel.  So far so good.  It didn't somke when power applied, and I was able to retrieve the DVDs that have been stuck in the unit. Next we will try it out at her place to see if it works the rest of the way! 

A couple of things I would say is that I wish I had a finer tip on my soldering iron, and I wish I had steadier hands!!!

Frustrated!
 I removed the DVD board myself and took the PCB to a Sony Authorized repair center. For $50 they applied the modified fix using the Q002 assembly and the 470 ohm Sony resistor. I re-installed the DVD board and screwed down the Q002 assembly as instructed. I applied power the the unit and "All Clear!" appeared. Cool. I switched to DVD and the screen went blank and 5 seconds later C-81 returned. WTF! I tore it all back appart and verified the solder connections and looked for a solder bridge. All looked good. I made sure all cables seated back into their grips firmly. Tried again and C-81!  What did I do wrong? I do not want to take this to a Sony repair shop and pay $179. Any suggestions?

Welcome to Agoraquest!  By Q002 assembly, are you referring to a HOUSING (Q002) ASSEMBLY that was purchase from Sony or something else?  Is it possible that the wires from the assembly were connected to the wrong points?  Compare your work with the photographs provided in my second post above.

I double checked under my kids microscope that they have a clean solder and they are connected as in the drawing above. The HOUSING (Q002) Assembly was purchased directly from Sony as was the 470 ohm resistor. The dreaded C-81 still appears. Any other thoughts as to why?
Thanks for the great website!

Sorry!  The only way I could do any more for you would be if I had the player in front of me so that I could troubleshoot it.
