I am having a JVC KD R-415 cd player in my car. it was working all fine but all of sudden ane day it started displaying PROTECT on the screen. i used the remote, press all the buttons and even reset the...

That is either an anti-theft protection, or it may just be that there is a short in the system. If it's the anti-theft, then you may need to call JVC for help, but note that they will ask you for purchase info on the unit to verify ownership. But, first, try and see if you have a short by unplugging everything in the back of the unit, except for the memory wire which should be yellow(constant 12V) and the switched power wire which should be red.(only has power when the key is in the on position). And last but not least, your ground. Now try powering it back on with just those three wires hooked up and if it works then there is a short on the system and you should be able to find it by plugging in one wire at a time until the protect light comes on then that will tell you where the short is.

I own a JVC KS-RF150 12 disc cd player,all of a sudden there is no power to the unit,checked all the interior fuses,radio is working fine and all connections to the unit are secure.Tried to reset it and...

Question ?
Are you using the remote to accomplish the power on
Check the fuses again it may be that the fuse in broken
2. To check some fuses you will need a meter to see if they Ohms reading if so the fuse is bad. Usually a fuse will read infinity if it good.
2. there may be a coupling capacitor on the main board that has become weak in the power section of the circuit board,
3. Also check all connector on the main board they could be intermittently connected
4. if you have power then a connector may come disconnected such a the ribbon cable to the power switch.
5. there also may be a diode or led that has blown that is in line with the power switch will not allow power to the switch for the disc player.
6. Voltage check at these points will tell if you are getting dc power from the transformer to the switch.

there are no lights on the changer. It has to be hooked up to a power wire(4-pins) and a controller that is mounted in/on the dashboard with a fm-modulator connected thru the radio antenna. You also need a jvc hand-held remote to turn it on/off and select the cds.

yes the rca's behind the radio are shot a power wire must of touched them.there is a small fuse inside the radio connected to the circuit board marked fu located and connected under the plugs in the radio. that must be replaced inorder to work. or if you want to cheat connect a grounding wire to the outside of the rca and it should work.

Can't tell what brand you have. I CAN tell you this.....On MOST brands that have a "bus" system (ie: Pioneer, JVC, Clarion etc) When you "add" a Sirius or XM tuner, the "other" input is on the tuner!It will (should) have an output (to go to head unit), and ALSO an input for another add on.

Make sure the cds are the right way up.
Try listening to the cd mech to determine if the cds are being loaded.
If the mech is going through the motions then the problem could be the lens is dirty, the laser has failed or the spin motor is faulty.
if there is no sound of the cds being loaded, it could be a power supply problem. Try a reset or just unplug the changer then re connect it.
