I recently installed this unit in my car and had finished the installation with 4 speakers and the unit was playing just fine until I walked away from the car and the audio suddenly stopped. I went back to the car and looked at the unit and it was still on and everything seemed to be in working order except for no audio. I turned the unit off and on again and reset the reset button on the front to no avail. I then removed the unit from the car and before unplugging it I checked my plug connection and it was good. I wiggled it a little bit to see if I could get any sound but that didn't help. I then disconnected the plug and I checked for continuity of all of my speaker wires and they were all good. I also checked for proper voltage on both the red and the yellow wires and they were good. One thing that I found interesting is tha when I was reconnecting one of my speakers I noticed a faint but distinct static from that speaker. I also tried connecting a known good speaker to all of the speaker wires one at a time but got nothing. That's about all I know to do aside from tearing into this thing and visually inspecting things for anything burnt or cold solder joints, etc. That's as far as I'm experienced to go so I think it's safe to say that I'm at a total loss for what could be wrong. Any help would be greatly appreciated.
Sounds Like your pr-amps are shot. You may have incorrectly wired the power lines up. If you are handy with a meter and check the middle legs of the pre-amps and see that you have continuity one way and none the other. If this isn't the case then they are shot or whatever ones dont pass this test. pop them out and order new ones. About $20.00

take one of the front speakers out and pull out the head unit and unplug a set of audio wires(front right, front left ect.) and hook it up directly from the radio to the speaker there for bypassing all the cars wires. If it works then there's a problem with the car's wiring(maybe an inline amp). If it doesn't work, then try a known good speaker from somewhere else(home stereo speaker for example) and connect it to the radio, if the speaker works, your radio is fine and there may be a problem with the speakers. If it doesn't work then you have a problem with the head unit.
I was installing a speaker and while drilling a spark flew. Didn't think anything of it and finished instalation. When finished the audio didn't work on any of my speakers. I have a jensen cd6112 and the unit seemed to be fine. Tuned in, the lights came on and everything. I hooked a radio straight to the speakers to see if they were blown and they worked fine. Is there a fuse in line with the speaker wires? I would hat to buy another jensen unit and the same problem exist. Any help? Is the jensen unit bad?
I bought a Kenwood KVT-815dvd player and got everything hooked up to only find out that it had a security code. The problem now is that I got it from a pawn store and they did not even know that it had a security code on it. So is their a way I can bypass they password or just reset the whole unit so that it does not have one. Also, where is the memory for this unit?
Hello....No Sound, No Volume Control, Mixer not Found, No Sound device installed…etc etc, This is a generic issue with Windows OS....many of the users are facing this issue.... 1 - r u facing NO Audio/Sound issue...? 2 - is ur Volume Control not responding ? 3 - is ur Sound and Audio Device in Control Panel Grayed out ? 4 - Do u get a msg "No Active Mixer Devices Installed....when u try to open Volume Ctrl etc etc ?
if ur ans to any one of them is Yes...then u are being spammed by Microsoft....ur Sound Control IRQ is being frozen by a recent update from Microsoft....NOTE..VERY..IMPORTANT...no file update or any sound driver update can fix it, neither Microsoft is issuing any patch to fix it…. Full solution is available in my website (Support page)...it's quite simple process to fix it, and I am not charging any money, just trying to do some service. www+sureshayyar+110mb+com Copy the above address in the browser, replace + with dots....all the best...
1) check audio driver is installed in system or not it may have some one remove audio driver. 2)If driver installed check volume is not mute. 3)If all thing is ok check speaker in another system by connecting it. 4) If spk is working in another system. it means sound card of that system is faulty.
Certainly, the output IC might need to be replaced, also check to see if there is a factory amp somewhere in the car.
Additionally, double-checking the wiring is a must.
How long does it take for the unit to heat up?
