Has anyone opened their radio for repair and/or know where to get a schematic for it?

I had 5 speaker codes during diag, all speakers tested fine. I have the radio out right now and disassembled it. There was some sand inside so cleaned that up. Tested the speaker pins through the board and they are OK. Did a visual inspection, no broken solder connections..... Just wondering if there is anything else I should check.

 

You didn't say what year your bike was or who made your radio, HK or Radio Sound?
Contact Radio Sound if '05/earlier. They repair on a "Flat Fee" basis.
Contact Iron Cross Audio about the HK radio.
Iron Cross are great people. They might be able to hook you up. Or it might be better to send it into them and get it checked/repaired.
They will let you know the best way to go.

 

It is a H&K from my 07 UC. I really need to put that in my SIG or something I keep forgetting to put that in.

FIXED!

I completely disassembled the radio, I took off the protective coating covering the pins for the speakers. I re-soldered each connector, covered in hot glue... and low and be hold it works. About 1-1.5 hours of work at most!

 

Good job, but please keep us informed.
That fix was posted once before, but only lasted a couple of rides.
From everything we know, it an inter-layer micro-crack or cracks that are both heat and vibration sensitive. You may have heated the circuit enough to temporarily bridge the crack.
Hope you got it, let us know...

 

You jinxed me lol, put it all back together and put in and nothing, same 5 darn speaker codes.... My soldering iron is only a 25W, it has trouble with 1 pin, going to get a 40W and see if that does the trick......

 

Gibby,

Not trying to jinx you, but I've seen this progression too many times. It's the same reason why there are so many repeat failures from the refurb program. The more times you attempt, the worse it may get. The chip is rated for only one insertion, so every time you resolder, you not only run the risk of worsening the crack, you begin to weaken the chip itself.

be careful, and good luck.

 

What chip are talking about? And are you talking about a crack in the PCB or a crack in the trace on the PCB?
