SOURCE: TX-DS838 shows protect and then shuts down

yes , Im afraid you have a chip gone , If you open the unit up you'll see a alloy heatsink with 4 to 8 large chips screwed to it , These are the amp drivers , In between these chips you see a smaller one (that is the protect chip),You see when things get a little hot this chip is designed to break sooner that the more expensive main amp chips , In the past ive unsoldered these and still found the amp driver bust too ,dont worry though , maplins or even farnell(cpc) on the web will supply these for less than a tenner..If you wanna test my fix then just unsolder the littlest chip on the main heatsink and it should start to work again but with NO protection(unplug it first before taking it to bits)
