[QUOTE="Llew, post: 632212, member: 175007"] That's a chopper IC Paul. Farnell have them - _http://uk.farnell.com/jsp/displayProduct.jsp?sku=9921427&CMP=KNC-GUK-FUK-GEN-SKU-OTH&s_kwcid=top234yn|3425065719 Normally any overload in the circuits after the power supply will switch it off via the feedback circuit. Could be something in the power supply itself, or just the IC given up the ghost. Best to check any components (diodes etc.) for any S/Cs before replacing the IC. Llew [/QUOTE]
