Anyone have an idea what could be causing my remote control system to only work some of the time?

Last night I proudly went to show my girlfriend how cool the remote features are, but neither volume nor switching worked anymore.    

The remote LED blinked happily away, but nothing happened on the preamp.  Everything had worked perfectly the previous day, and the unit had been running continuously since then.  Turning the preamp off and back on didn't help, so I guess it's not a Windows cache problem. . .

I left the GK-1R on through the night and lo and behold, it was working again this morning!

What would you suggest to debug this problem?

Thanks in advance for any thoughts,

Dayne,

Sounds like a power problem;  the microprocessor may not be actuating because there's no power.

Leave some clip probes on the power supply to the digital pcb and monitor the 5V supply.  If this is indeed the problem, no voltage there when things are dead, then it's likely to be a dry joint somewhere.

Hope this is helpful,

Cheers,

Hugh

Hi Hugh,

I couldn't seem to measure C2 correctly with my DMM, with was showing 0.9 nf without being attached to anything.  The ceramic disc has 102 printed on the side.  Is that correct?

I'll check the voltage the next time it stops responding.

Thanks!

Hi Dayne,

102 means 1000pF, which is 1nF.  Right on the money, Squire.......

Yes, do check the voltage next time there's a problem.  Any fluorescent lamps in the vicinity?

Cheers,

Hugh

Hi Hugh,

Good news on the capacitor!  Maybe some century I'll start being able to recognize and understand the cryptic descriptions on them.  For now I'm very glad your instructions usually include helpful hints like "...the so and so capacitor, which is one of the little yellow disc thingies".

No, no flourescents in the area.  I really dislike the quality of light most flourescents throw. . .
