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 Dana

    I forgot to add one more note about the speakers--I can still hear a slight hissing sound coming out of the speakers when their not working properly, but that is it. Thanks again

    I also forgot to add that I have no sound when I am doing the tone test--not just while watching movies--this is how I know that I have it fixed--I just keep it on the test while I climb back there and dink around with the connectors--they really seem to be in fine shape though...

    Hate to keep adding to this already lengthy post but I feel the need to add this--mind you I have done nothing to this thing since I first posted but now all speakers are working on the tone test. Earlier tonight I tried it and got just one rear speaker to work and the center. I touched nothing since and now all five speakers and sub woofer are working--what is up with this?? Still a crappy picture though..

Sherwood AX-4103 amp keeps clicking


Hello there.... Check your speaker wires and then if that doesn't do it? try replacing the fuses on the back of the amp.. make sure power is turned off and unplugged. If that doesn't work? Try one speaker at a time ... something is causing the system to short out. Hopefully it is not internally

My advent notebook has started to make a very loud buzzing noise intermittently, much too loud to be caused by mobile phone interference etc?


If the noise isn't coming from a speaker, you could need to replace the fan on your computer. The bearings for it might be busted, another issue could be the speaker wire isn't fully connected internally, which you could fix by popping off the top power panel area and fastening the speaker wire in it.

I hope this helps, if not I apologize. The question isn't super vague, but it still has holes in it. :) I can to help more if you post more about the issue.

Hey, I have a Onkyo TX-D777 Receiver that has a problem and am hoping someone can help. The receiver will come on sometimes and then it will go into protect mode and not come on again. If I let it sit for...


It sounds like you have bad solder connections on the audio output ic's junction points, it's also possible the internal ic,s might be breaking connection which would explain the intermittent operation of the receiver. But to be on the safe side check your speaker and wiring connections very carefully on the back of your receiver. If that does not do it you will need a technician to carefully go through your system and make any necessary repairs.

Turns it self off intermittantly and it is not overheating


Check for a speaker short or wire touching, beyond that, it would have to go on a bench for testing. Probably a cold solder joint if not a speaker or wire. Hope this helps

Sony Vaio vgc rb52 no sound ... speakers work/computer sound won't work?


Hello there... Check your PC's volume. You may or someone in your household has accidentally muted it. Unmute it or increase its volume (if you can't find the audio icon in the taskbar, proceed to the control panel - it's there), it maybe too low. Hope this helps... Ai :)

I have a jbl 525 powered speaker but it wont play full range it will come on and out, playing only the highs at times


Check the incorporated capacitors (if any), also inspect the braid speaker wire on the bass speakers (i understand that these are cutting out).

The braid wires are located between the speaker connection terminal and the speaker cone - if these are damaged or broken, this can cause the speaker to cut out intermittently. To see if this is the case, try to push the speaker membrane gently inward when the speaker cuts out - if it momentarily regains function, then the braid is almost certainly damaged.

Braid wires can be resoldered, but it's not a very easy task because of the structure of the braid, which makes it difficult to clean and solder.

You should have it repaired by someone with good soldering skills or at a speaker repair shop, otherwise the alternative is to replace the speaker.

New car head unit, same old problem: Garbled sound


Hello susanmillan,

If it's not the head unit, and it's not the speaker, then it must be a problem with the wire going to the speaker. When you hit a bump, the wire shorts or opens intermittently causing the faulty sound. Some insulation could have rubbed off. There could be a bad pin in a connector. The wire could have some broken strands. It could have become pinched against something sharp.

The good news is, it's really an easy fix. Just have your installer make sure that the sound is OK at the wiring harness itself, and run a new wire from there to the speaker.

Hope this helps.

Panasonic stereo help


It sounds to me like there is a dirty connection or a failing component in your stereo. Being intermittent like you've described, is hard problem to figure out. It could be just the connection you are getting at the speaker terminal. But, If you aren't shy about opening up your stereo to see the guts, try getting some denaturated alcohol and clean the connectors inside. Then if you are familiar with soldering you could check the connections in the driver circuts and see if you can re-flow some of the connections. I had that problem with my receiver. The video output was be flaky so I flowed some new solder on some terminals and it works perfectly.
I hope things work out.
