Our Sony c 770 no longer plays DVDs or Cds but it still works as a receiver. Can we connect a DVD player to it and have it come thru the 5.1 speaker system?


Hi,
Yes, tis unit has 2 video inputs at rear so you can connect any other dvd player sound (analog or digital) to get 5.1 channel surround sound from DAV-C770 speakers.
Click Sony Support to download user manual copy of DAV-C770 that has more details about connection setup.
Hope this info will help you.
Thanks.

Sony Dav-C770 blinking standby light product will not function


I had the same problem, red blinking light after owning for several years. I decided to replace the capacitor at C914 to see if it would work, and it did. Apparently that capacitor is prone to failure. Since this seems to be a common problem, I created a web page detailing the repair. Hope it is helpful. Repair cost $1.39 + tax.

Blinking standby light system will not turn on


I was having a similar problem and determined that there was a short in the speaker leads for the center channel speaker. The leads to the speaker were touching, after being moved, slightly while housecleaning. Once short was eliminated, unit powered on and worked with no problem.
