Jvc chk wiring then reset how to#
I know how to do that lol.Īnd I spent about 30 minutes today going through every circuit board with a flashlight and a magnifying lens to look for any more physical damage. I fixed the burned trace as soon as I got it apart. im sure someone has one of these with a busted screen or some other issuesĮvery single feature works on it I tested every menu and option
Jvc chk wiring then reset plus#
I bought it for 60 plus shipping so even if nothing else works out I think it still worth about 150 if I sell it back on ebay or craigslist. looks like you has done "gots" yourself, one "Dell of a Heal". I am expecting your audio power amp to also be using one of those *** like type of units, look around and see if you find one more similar unit on a heat sink, near your audio speaker output connections. The NAV system, its display and uP is needing power requirements as sophisticated as a laptop. I am vaguely seeing the left one as providing multiple power supplies and the right one, as one that provides 1 or more POWERFUL supplies. Pass us all the numbers from those big *** modules so that they can be function identified. (Your pic didn't go far enough back in between those TWO Potted Power IC's *** to show the component side view of those connections. Where you had reworked those heat crazed "gray" solder connections, what two components wire leads, were those two involved wires being connected into ?. 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
