Unfortunately that is how this unit is designed, you cannot adjust the volume while inputting from an external source, normally the subwoofer would have an AUDIO control, but this one has no knobs, the VOL +/ VOL- on DVD remote only controls while watching a DVD. Only work around for this is if your TV has a 3.5MM headphone jack, you can get a 3.5mm to RCA cable and then your television would be able to control the volume.

    I just got one of these systems and I have this same issue, this is a serious design flaw any company that designs their products this way should be wiped off the planet. I wanted this system to go with my new 40" 1080p lcd that has no headphone jack nor should it, This product should come with the volume controls on the tom like I have seen on other products without the dvd combo.

Need a manual coby dvd765 theater system


I run into this problem quite a bit.
According to the Coby web site, there is no 765.
The closest thing to it is the 755.

When you go to sites like this, dont click on the giant "DOWNLOAD" buttons as they are always advertisements.

Can't get cable sound to run through surround sound


You would have to have a cable box, from the cable box, you would hook up the yellow to your tv, and then the red/white audio would go to the subwoofer on your DVD765 where it is labeled (TV), you then hit the switch on the subwoofer to TV. Another option is if your TV has audio output, you could just run RED/WHITE audio from your tv to the back of the subwoofer where it is labeled (TV).

I have the coby 765, when i switch the buton to tv it is very loud even with the tv and dvd player turned completely down


Unfortunately the subwoofer should have a volume control knob, and the subwoofer for the DVD765 does not have this, that is why it is so loud, the only work around is to get an audio cable with a built in volume control knob.

My center speaker is humming after i turn the tv on.


If you center speaker is humming, you when you turn on your TV, you may have the audio signal over amplified and the hum may be coming from your TV itself. Try moving the speaker further away from the TV or the amp further from the TV and see if it solves the problem.

Coby DVD765 Theater System and can't control the TV volume through it...I saw the previous post...We have it in our bedroom and rarely watch DVDs in there. Could I plug my RCA audio cables into some of...


The connections will have to go directly into your tv set. On your tv, you should have 3 connnecting points. Red, White and Yellow. On your Theatre system amplifier you should have audio outputs like CD, AUX, etc. Pick one of these outputs and connect to your Red and White RCA on the tv set. Next, connect the DVD player's audio to dvd on your amplifier under the DVD connection. Your VIDEO (yellow) Cable should still go to your tv directly from the DVD player. Now, if you want to listen to the TV channels throug the system, simply select the channel that you pluged the TV audio into. Hope this helps.
