I have a jvc kds-16 receiver. It has been working for about 5 months with no issues. Now there is power to the head unit but I have no sound. I have checked all of the connections, nothing is loose, the ground is good, and I have tried the reset button. still no sound.

What you should try is this. see if you have 12 volts to the yellow wire. the yellow wire controls memory and things like that. it should have 12 volts constantly. also look under the plug on the back of the radio, make sure it is not blown. it acts like the fuse on a power amp. if the fuse on the side of the power amp is blown, the amp will still power up but the fuse is not letting power to the power relays inside to kick the sound outputs on.

Buy a digital volt meter and start checking fuses for the radio at fuse panel . if blow replace it . if not blown remove radio from dash check to see if radio is still grounded . if still grounded take the volt meter turn on to dc volts and take black test lead touch to your radios ground the touch the red test lead to the red with to see if you get 12 volt with car on if not need to find out why .. take to professsinal ..

you can also check the yellow wire on radio it should have 12 volts allways doesnt matter if car in off or running this saves memory for clock and station presets.

if every thing is test out right then you need to buy new radio ..

if you dont feel good about doing this yourself find a mecp car audio installer and have them troubleshoot your problem maybe expensive but a good tech could find out problem with in the first 30 to 45 minutes it get 35.00 per hour to troubleshoot car audio system ...
