Yes,the portable DVD player u have now the main LCD viewing screen it is dead.Noth worth fixing by replacing the main LCD viewing screen parts and the labors of a tech. to do it.Will cost about the same as a brand new one.
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 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.

There are two things. First check the sound settings of the DVD player. It might be putting out a lower quality sound on the CD side of things.
Secondly try to determine if the speaker tweeters are working. Connect the speakers if you can to another sound source. If the speakers are good and the settings fine. Then you have a fault in the amp unit.
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
Have you tryed a differant audio input on another set or on that same set. Are the audio cables good?? If all this is ok then the D/A converter inside the unit is defective and most likely it wont pay to repai sorry
