Sony DAV-C900 Home Theater System: problems with speakers and dvd picture quality
Hello all, I hope someone can help me here...
The speakers have been going off and on intermittently for a while now. I have cleaned the connections, but it does no good. Sony has these stupid color coded connectors and I do not know how to go about upgrading the wires. If that is even the problem. I have switched the wires around, and when I switch one that works to a non-working connector it will not work. When I put a non-working speaker wire into one of the working connectors, it will work--it almost seems to me that it is either a problem internally, or with that specific connector that sticks out of the rear of the unit. After fooling around with them for a while, I can usually get it to work, but then it will go out for no apparent reason. Another problem has to do with the picture. It has developed these squiggly lines while watching dvd's. Sometimes they go away after a while, but it is certainly annoying. I have attempted to clean the laser with one of those dvd cleaning disc's and even replaced the s-video cable, but neither has resolved this problem. It used to have an excellent picture, even though I wasn't using component cables. Due to my TV set-up, I need to use the S-video hook-up, but like I said it has always worked well until recently... We really do not watch that many movies, so I wouldn't think the laser is going bad--hell, the kids have many more hours on their xbox than this unit has...If I had the money, I would just go out buy a new system--not an HTIB this time, but this year has not been too lucrative, so I am stuck with this for the time. Any help will be greatly appreciated. Thanks

Hi, First try with yellow video output of DAV-S500 in yellow video TV input to get its picture. (yellow output means composite video out) Green-Blue-Red video output is component output that will be turn on when you switch the unit into Progressive picture mode, that option would be available in Menu of DAV-S500 Hope this info will help you. Thanks.
As long as the cables are properly connected you shouldn't lose quality in the sound. If its the front speaker cables you want to extend then contact sony and ask them for the rear cables which you can then substitue for the front ones which are considerably shorter.
Please check at rear of TV for Digital Optical IN port as home theater should have optical out port at rear. If you got any optical in port in TV, just connect optical wire between TV and home theater.
2nd option is check Line Out pins at rear of home theater system, if found, hook red-white RCA cable there and put it to same input in TV where you hooked Video (composite or component) cable.
A bizarre coincidence but our Sony DVD player DAV C700 did exactly the same when the kids were watching a DVD. All other functions on the system are still working but the DVD player wll not eject or play - and the self diagnosis function C 81 remains illuminated on the display.
sounds to me like you got a short circuit of some sort, probobly some bad wiring. try disconnect all cables connecting DVD, TV, speakers and such, and reconnect the again. just take into consideration that this is a longshot, and chances are its an internal problem.
