Has Sound but no picture

Unfortunately, 2% to 4% of consumer electronics are either defective on the store shelf (I got my TV home, plugged it in, and it wouldn't turn on) or they develop a defect during the warranty period or shortly thereafter. So, even though you just bought the unit two months ago, if you have sound but no picture, the unit needs to be repaired or exchanged.

As long as you have the receipt, you should still be in warranty since the shortest warranty for name brand electronics is 90 days from the date of purchase. Contact the manufacturer to obtain the warranty procedure. This will likely involve you sending the unit back to them at your expense and they will send you a repaired, refurbished, or new player.

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.

Have picture, no sound

I've had this trouble too. Not sure how to fix it, but I've found a work-around:

Remove DVD.
Insert Audio CD.
Wait for audio to play.
Remove audio CD.
Reinsert DVD.
Sound should work again.

If you power off the unit, you may have to try this procedure again.

The problem is the tape mechanism is malfuctioning. It trys eather to load or play a tape and a sensor inside tells the microprocessor to shut down this mechanism before damage is done to the tape. BUT sometimes a malfunction causes a damaged tape too. this unit has NO user serviseable parts inside itself, so its time to take this puppy into a repair shop to see if its worth the repair , Unless this units more then a few years old?? then its time to buy a shiny new unit. Good luck

DVD Player makes a slight "tick,tick" sound during playback

I would certainly take the unit back cause that noise could be the tracking or focus coils making that noise as they are being overdriver. This could cause the unit to fail prematurly. Its not an adjustment that you can do your self, it takes special equipment and disc

Dvd audio quieter than vcr audio

There may be an audio adjustment in the dvd player that wasenr set up at the factory correctly. depending on how old the unit is I would contact the manufacturer and see if its under the factory warranty as you DO NOT wanna go inside and start turning controls as this will or could throw the entire alighnment out of the dvd player. I(f theres no warrantee then you could ask them if theres an audio output adj and what the pot # was. Or else your gonna need to get a service manual and throw ya back a few bucks. But my guess is that if you bug the service guys enough they will tell you where the adjustment is. Good luck
