  1. I used a solder sucker to remove the old joint then soldered it again. It isn't perfect. But it isn't a mess.

    Plugged it into the fiio e11, because a 20 kilogram DAC into a 20 gram amp is the done thing. Left channel is working fine and doesn't cut out if tapping or torque is deployed. So I venture to hope that it's fixed.

    DAC Saved! Thanks all! smile.png

  2. Thank you so much for the input so far guys.

    I don't think it is an issue with the relays (parts labelled OMRON) as a bit of work with forefinger and thumb confirms that tapping on those or anywhere else does nowt, while applying torque clockwise or anticlockwise to the large black capacitor (C334) brings back the music. This force might be moving the relay as well of course. I'm going to bring the DAC down to my desk and dig out my soldering iron. I hate moving the DAS-R1 because the mains lead is captive and getting it out means unbolting my drawers from the wall. Back soon.

    Kevin if you link me to the schematic I'll buy it and post it. Least I can do.

  3. So for a little while now my Sony DAS-R1 has had a problem with the left channel cutting out. It used to get better by itself after a minute or so, then it needed longer. Now I have the lid unscrewed all the time and give it a wee tap. While this cures the symptom it doesn't cure the disease and the wee tap is now turning into a prod, before I know it, I'll be using a frame hammer.

    I'd like to fix this myself however I only just know which end of a soldering iron plugs into the mains and which end you use to burn your fingers touch against things to heat them up.

    I've looked under the board and I cannot see any obviously broken connections. I am fairly certain that the problem is in the connection to "the big black cube". Simply because that's where I'd tap for the most sure fire results.

    I throw myself upon the diagnostic wisdom of the great and the good here.
