Boon Posted April 30, 2009 Report Share Posted April 30, 2009 Righty... the other day I was doing the fusible link on a Pioneer P80RS and decided I may as well photograph the process. It's pretty much the same for most Pioneers from the last couple of years. So here we go: Here's the victim Remove all the screws with arrows pointing at them Pry the top off, you'll need to get at it with a flathead screwdriver but if it isn't coming easily you probably missed a screw... Unscrew the CD drive part. There's usually 4-5 screws, some of them are in odd places like down the holes at the front. You'll want a magnetic screwdriver for this. Lift out the CD drive. It usually has 2 cables going to it. Disconnect the ribbon cable by gently lifting the 2 tabs on each side of the connector. Then unplug the other connector and put the CD drive to one side, exposing the board. Unscrew this little clippy thing and set it aside Disconnect the front panel ribbon cable, same way as the CD drive one. Be careful, it's quite fragile. With a pair of needlenose pliers gently bend these little tab things so they're in line with the holes in the PCB. Try not to over-bend them as we don't want them snapping off... Unplug this connector Remove any screws holding the board down (there might be 1 or 2) then remove it from the casing Here's the topside of a P80 And here's the underside On the P80 the fuse is on the top, right beside the RCA plug connector thing. On some it's underneath the PCB but it's usually not far from the RCAs anyway. Here's the little bastard. They are usually white and have a little P on them. I don't know if all models have the /!\ on the PCB beside it. Now my camera ran out of battery here I'm fortunate enough to have a hot air station so this was a piece of piss for me but if you're using a normal soldering iron: Heat the whole fuse. Heat both ends alternatingly then heat the whole body of it. Keep heating it until it slides off the pads or comes away stuck to the tip of your iron. Don't force it, if you mess the pads up you're in trouble. Once you have the fuse off you can simply dump a blob of solder between the 2 points. Personally I like to clip off a little bit of a leg from a resistor or something and solder it across the gap but there's nothing wrong with a good solder blob. Follow the pictures in reverse, be very very careful with the ribbon cables and make sure they're in the connectors properly before clamping the little tabs down on them. Enjoy your new noise-free headunit and don't worry about popping the link any more NOTE: The fusible link is there 'for a reason'. If your ground falls out of your amp the fusible link will usually protect your RCAs and headunit but obviously the stops that happening. You'll probably burn a ground track instead, like any other headunit. I take no responsibility for anything that happens as a result of you messing around with your headunit. This guide is purely informative, you should not do anything depicted here, and I'm not responsible if you choose to. 10.x volts fo' life! Link to comment Share on other sites More sharing options...

jvillefinest Posted April 30, 2009 Report Share Posted April 30, 2009 dont know why but some get the problem and some dont.lucky im the latter..always wondered what that damn thing looked like..good schooling glad you didnt but i know when i was selling pioneer i had alot of them come back quick because of it. Or i would have a pissed off installer asking me why i sold a customer on this shit. It got to the point i would straight tell a customer what kind of a POS pioneer cd head units are. It always made an Alpine an easy sale, with less headaches for me and my installers. I have always said if nav is your thing pioneer might be where you want to look, if its not leave the POS alone. EDIT: GREAT WRITE UP THOUGH. I just think its crazy that you have to do this to a "quality product" straight out of the box. 2007 Acura TSX Stock Navigation Rockford 360.2 (FOR SALE) Sundown SAZ3500 2 12" DC Sound Lab LvL4 @2ohm JL 600/4 2 Sets of Focal 165K2P Link to comment Share on other sites More sharing options...

I was extremely pissed after i found out, and they where onsale too so i guess he much have got his little commission. Link to comment Share on other sites More sharing options...

jvillefinest Posted April 30, 2009 Report Share Posted April 30, 2009 lol im sure the extra $5 he got for selling the pioneer it probably wasnt worth it after he had to swap it out over and over. 2007 Acura TSX Stock Navigation Rockford 360.2 (FOR SALE) Sundown SAZ3500 2 12" DC Sound Lab LvL4 @2ohm JL 600/4 2 Sets of Focal 165K2P Link to comment Share on other sites More sharing options...
