SOURCE: JVC KD-R200 won't power up for more than 5 seconds

Check your wires they might be touching steel around your car mostly look at your yellow and red wires those are the 1' that give it power and light to your radio also check your radio fuse in the back.

SOURCE: JVC KD-SX780 All of the sudden--just stopped

There is a grounding tab on the back of the unit just above the antenna connection. This must be solidly connected to a GOOD ground. Found out the hard way myself. Once ground was established, I never had that problem again.

Please help!! i recently got a jvc kd-sc800 system off a buddy for my car, only problem is it doesnt turn on to be honest. every time i hit display it shows the display for like 5 seconds then seems to...


Please check if the connector of the faceplate and head unit don't have dirty or bended pins, these can produce false contacts between them and can produce fails as the one you have, if this is OK, maybe you have a bad faceplate or head unit.

Wont turn on


  1. go over all the wiring and make sure nothing came loose.
  2. find the reset button usually behind the face. reset the radio.
  3. make sure the face plate is completely on the head unit.

JVC KD-SX780 All of the sudden--just stopped working.. If you touch the "display" button--the display does come on briefly--otherwise nothing.. Any ideas??

Kd-s5050 wont stay ON


This is Common on Vauxhalls...

The Accessory position on the Ignition fails!

so the Ignition connection is temperamental... The unit has power and so certain functions using the constant 12v.

I normally connect the ignition to a different source.

Or a quick fix is to connect both red & yellow to the constant12v

Error 10 message on display screen


Same issue but pressing Power and SEL would not reset unit. Found solution. Once again disconnected the car battery. Removed the face unit from the radio base and then reconnected the battery. Replacing the face unit AFTER the power was re-established solved the issue. (Probably pulling the radio fuse rather than toying with the battery connection would have done the same thing.)
