[QUOTE="krys_k, post: 105639, member: 186512"] Thanks for your help. I took out the board and couldn't find any dodgy soldering - it all seemed as it should be. However, by using a toothbrush I indentified one of two components that when tapped colour returned. I am not sure which of these two is the guilty party. The first component was a flat, retangular box, with metal 'legs' running down both sides (aprox 5mm x 20mm). It was labelled TDA4510 22 1220 DSD95098 The second (and i think more likely) was a black cylinder, aprox 30mm hight and with a radious of 8mm. It was labelled on one side: (M) 85*C 4(2) Nb And on the other: 16 SME 2200 V mF Does this make sense? Is it one of these components, or am i missing a soldiering point? What should my next step be? Many thanks for your help. I really appretiate it. [/QUOTE]
