[QUOTE="jdfp, post: 519266, member: 290244"] Thanks for your reply Llew. Further investigation has revealed that there is no direct short on the mains input side of the board. However I have found the reason for the loud bang, IC1 KA1HO565 has exploded, blowing off part of the casing! I fear that the component is not as robust as Fairchild's data and application sheets claim it to be! I can find no source for the component and so it looks like I have a dead Echostar.
