Were any fuses blown and are you currently testing through an ~ 15 A fuse?,( IF power is fed in thru an inline fuse holder.). Meaning that the NAV system and its display is, at the least, now showing minimal info ? and everything works except theres (sic) no sound from the speakers. So after repairing the trace I put it together. JVC is now merged with kenwood btw for few years so I would assume their circuitry would be very similarĪnyone have a link for me or something to read on the topic would be great. I know the notorious pioneer surface mount fuse but I don't think jvc uses it. I'm assuming its something with power supply or blown amp. I haven't got the stereo yet but I was wondering if anyone here knows how to test a dead car stereo Just checking for blown caps and blown amp and input diode. I only found 2 videos on where to start troubleshooting car stereos and there wasnt much there Its more of a project for me since it was damn cheap. I fixed few items like thatĪnd I have a voltmeter and know how to use it lolīesides that I have a general idea of how things work but no more than thatīought this unit for 80 bucks on ebay seller says dead no power at all I'm somewhat of a noob at advanced repair.īut I do know how to check for pulse and breathing etc

Jvc chk wiring then reset
