On my coby 765 dvd player 2 out of 5 speakers work the rest just buzz

Step 1 Select locations for each of the Coby 5.1 speakers. Place the correct channel speakers in the best location possible. For example, a right-rear speaker should not be placed to the front left of the TV.
Step 2 Measure and cut lengths of speaker wire that run from each speaker to the Coby receiver. Include a few extra feet for mistakes. The speaker wire has two color wires, a red (power) and black (ground).
Step 3 Attach the red wire to the positive (+) terminal for each speaker. Attach the black wire to the ground (-) of each speaker.
Step 4 Make sure the receiver is unplugged. Examine the back of the receiver. There are speaker terminals for each of the speakers. Plug each speaker wire into its respective terminal. For example, plug the right-rear speaker into the right-rear terminal. Each terminal is clearly labeled.
Plug RCA cables into the appropriate input ports on the receiver. For example, there are RCA ports for the TV and DVD player. Plug the other ends of the RCA cables into their appropriate devices. For example, the DVD input on the receiver plugs into the audio output port on the DVD player. RCA audio cables are red and white, make sure to match the colors correctly: red with red, white with white.
Items you will need

• Speaker wire
• Wire stripper
• RCA cables

Check its audio output circuit for damaged component/s, provided, iv video is OK.

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.

Unfortunately, I don't see Coby 206. There is a 207 however if that would work.

TFdvd1020, no audio ,funciona bien pero no se escucha ni los speakers ni con el cable av

I know this is not the answer that you want to hear, but: That television is not capable of delivering audio output to all 5 speakers - it is a stereo-only TV, which only delivers 2 channels.

Furthermore, that Coby DVD-937 only has Digital Audio outputs rather than inputs, which is very strange and complicates our problem immensely. You will get 5-channels with DVD or radio play, but getting 5 channels for TV is not possible without additional equipment.

The manual for the Coby mentions a "Digital Decoder Amplifier," which would work. You would connect a digital audio cable from the area marked "Coaxial" on the back of the Coby to a digital audio IN on the back of an external amplifier. You would connect the speakers to this amplifier, instead of directly to the back of the Coby. Then you would need a cable or satellite box with digital audio outs (fairly common nowadays) to another digital audio IN on the back of the amplifier. The cable or sat box you may have already, but you may need to purchase such a "Digital Decoder Amplifier" or other digital amplifier with appropriate speaker wires and 2 digital audio input slots (not to mention two digital audio cables). Fairly complex. Possibly expensive.

Try this, it is the only known hack for Coby R1000:

Coby DVD-R1000

1. Turn on the player (without a disc inserted)
2. Press STOP 2 x
3. Press SUBTITLE 5x
4. Press the button for the desired RC (0=codefree)

Let me know if it works.

Thanks for the tip on Colby mp3 I won't buy that either. The RCA mp3 isn't much better.

I sucessfully programed the AUX button on my Cable remote to my Coby DVD player (model DVD-227) using code 21107. You can also try these codes: 20778, 21086, 21351.

I hope that helps!
