Date: Mon, 04 Apr 2005 04:34:24 +0100 <snigger> fw little iw ...my wild guess is that when the circuit blew, you _damaged_ something 'near-by' (ie a transistor/resistor) This may be causing just enough overload to the main device to trigger it's repeated demise ...I am sure that the right amount of work may track down the fault - but in honesy *I* would give up about here or you could be chasing dead components around for ever on a cheap-to-replace device. Replacement? ebay and another little mp3-only archos unit ...at least until Rockbox is dusted off for the new super colour all-codec units in the pipeline. Sorry, not words of encouragement from me :( ...but, as is my way, the truth as I believe it to be.
