Many car stereos use an anti-theft pass-code scheme. If the stereo is removed from the vehicle, lock-off is triggered by the loss of battery power to the stereo, and the only way to get it to turn on is to enter the pass-code on the front panel buttons. If you had to disconnect the battery, or it went completely dead on you, that's your problem. Check the manual for your stereo for details.
Note: some stereos requiring entering the pass-code before disconnecting the battery - for those who might have such systems, save yourself some grief and check your user's manual ASAP so you are prepared.
Another possibility is a shorted speaker amplifier has blown the radio fuse. Check the speaker wiring for damaged insulation before you install the repaired or replaced stereo. A competent electronic technician can generally check the amplifier modules or transistors for shorts and replace them as needed. Be sure to ask which speaker output is bad so you know which one needs a wiring check.
Check your car battery. Try to turn off your headlights and aircon then look at your stereo if its bright, if it has bright light try to turn on your aircon and headlights then if the light of your stereo turns dim the problem is now on your car battery. The battery cannot supply all the electricity needs of your car.
If the cd's come in and out fine then it has something to do with key wire (red) . I try and always use and a adaptor harness when installing aftermarket decks. Make sure your wires are well inulated and not pinched when deck is "in its place".
Sounds like you have the ground for the radio hooked up to the illumination ground wire. Check for orange or orange/black wire coming from the radio harness. Did you buy the harness for the car as well? If so then just match all the colors of wires from the car harness and the radio harness. By car harness I mean the harness that plugs into the harness that the original factory radio plugged in to.
Check all the connections with an analogue multimeter set to 12 volt dc.You should get fsd at all points. There is no doubt that you have an intermittent fault on the wiring.However, there is a slim possibility that this fault may, in turn, have caused damage to the clarion.If you cannot find a fault on the wiring, then consult a repair manual (available to download) to see whether or not there is a fuse inside the clarion. If there is one fitted, check that to see if it is blown. If thate above does not sokve the problem you are welcome to email me for further help on firstname.lastname@example.org. But I think fokkowing the above advice shoukd solve you lack of sounds in your car. All the best
Hoang00, to change the time on JVC's i believe you hold down "source" for a while and a menu pops up. SSwaim, sounds like a grounding problem. Check the connections behind the dash, possibly a couple came loose. I would say possibly a bad car battery but the headlights thing points to a grounding issue to me.
just solved a similar problem on my car i
bought a Cd/dvd player for my 2000 concord lxi i hooked it up and
hooked a rear-view camera and it worked perfect but wen i turned the
headlights on the cd player shuts of so i disconnected the orenge wire
that came out of my cd player from the orange on the aftermarket harness
then grounded the ping wire (rear con wire) it worked fine but i
couldn't see any footage from the camera for that i bought a long red power wire
and hooked it to the red camera power wire that hooked from camera to
reverse light and took the other end of the new wire i bought and hooked
it to the orange wire that came out of the cd player now every thing
works fine. you probably dont have the right power to run both cd and head lights
thats why you need constant power to run both just hook up an extra
wire between a positive wire to the orange dimmer wire its simple;
ground to ground (black)
12+ positive to 12+ positive (red)
and an extra wire (usually a red 18 guage wire bought mine at walmart)
to the dimmer wire from the back of the cd player (orange)
