Question about Coby DVD-755 System

2 Answers

Subwoofer feedback, and no sound

Hi, got a new theatre system for Xmas. Its a Coby (CS-P63), with a DVD-755, the TV is a magnasonic. The dvd player plays music cd's, the FL/FR work as they should for the music ( I used these plugs to check all the speakers to make sure they worked), and they do, so they are wired right. However, the sub has a low hum, and when I put in a dvd I only get sound from the TV. I think there is some sound from the centre speaker, but no dialogue. i triple checked all the wiring for the system, and tried all the options in the manual, but have gotten no results. I tried to contact the company but of course got machine after machine and no humans. I sent off an email but expect no answer. I also tried to adjust the audio on the setup in the dvd player but only have the options of changing the room type, and that's it. the volume on the Sub doesn't seem to give any results either. What am I doing wrong?

My sub does the same thing. I hooked it, (my sub) up as the center and it worked fine thinking that it was the center speaker. Changed to different wires as well. It has to be a configuration issue that is somewhere telling the sub not to work within its proper capacity but I have checked everywhere within the menus on mine as well to no avail.

    Try a different set of stereo cables from the DVD player..Hum says there's a ground wire /shield wire broken or not connected.

3.5mm is stereo sound, which means 2 speakers. so no there isn't a cable, u could get a 3.5mm to AUX cable, but that would only play sound out of the front 2 speakers and the subwoofer. otherwise you would need a device that supports 5.1

I have a coby dvd player which is connected to my home theatre sound system. However, i canot increase the volume to a satisfatory level past #20. the theatre sound system is at max volume.

I work for Coby technical support. Our customer service phone number is 1-800-727-3592.

Unfortunately, there is no way to increase the output of the Coby dvd player within the player itself. It may be that the player isn't outputting very well through the audio coaxial output which i presume your using. If this is the case, there is no fix for that type of issue. You would want to replace the player.

If you feel this solution doesn't deserve a good rating, please let me know why so that I may better assist you. If there is anything more I can do to help, I will!

COBY cs-p63 ,how to connect to a computer


with this system it comes with connector cables, on one end is 3.5mm to go into your computer and the other end is rca jacks that go into the subwoofer, all the speakers go to the subwoofer. your computer must have all 5 ports to get true surround sound, if not, just hookup the ones for the FL FR and run RCA split from that to the speaker output on your computer.
