Date: Wed, 29 Oct 2003 21:40:25 -0600 Well, I tried some surgery today. First, I found that it is MUCH easier to remove the smallest PCB by cutting the two metal tabs instead of unsoldering a BUNCH of places. Nice tip in the disassembly instructions! I found the little switches to be a LOT smaller than I expected them to be. I assumed that perhaps there was just a cold solder joint on the particular switch. However, I was not expecting them to be surface mounted. Looks like they would have had enough room to use a rubber-like button on a contact on the PCB like they do in all recent TV remotes. I wish that they had. TV remotes seem to last forever, even when I constantly use the up/down channel buttons. As you stated below, the problem is the switch itself, not the mounting / soldering. I'm thinking that perhaps the easiest thing to do is to remove the unused LINE-IN port and install a small pushbutton switch jumped to the appropriate lines. Of course, I'll have to be even more creative if another button stops working... If anybody knows where the same switches could be purchased from I'd bet they could sell a bunch. I'd replace all six at the same time as long as I had the case open. I'd buy a few spares as well, knowing how unreliable they are. Thanks for all the suggestions and help!!!!

I've had the same problems with nearly all the switches in my JBR. I haven't found any distributor for suitable replacements switches (they're extraordinarily flat) thus I unsoldered the switches and opened their housings. In all these switches the little contact metal "disks" (the things that were supposed to go 'click') were cracked. I managed to rebend these thingies so that the switches worked - for a short while. Unusual high pressure was necessary to operate some of these repaired switches. This pressure bent the pcb slightly - to much in the long run. Some wire on the pcb seems to have suffered a hariline crack. Now the unit crashes at random. Resoldering each single solder point didn't help and I can't find which wire is broken. -> The unit is beyond repair. :( Phil Received on 2003-10-30 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
