There were a range of LG 42 inch sets where small blue capacitors go S/C or leaky - these are mounted INSIDE the panel (rather strangely!).

It was a common fault, and an obvious 'manufacturing defect', the examples I've seen were all given their money back (and left with the TV which was thrown away).

Check if you can smell burning at the LHS of the panel, looking from the back,

I was commenting on Nigels post, if the caps in the suspect LG 42" tv's are not accessible, thought it would have been a easy fix from the mfg,but if buried somewhere in the panel maybe not so.

No, inside the LCD panel - I did have a try, and stripped the entire LCD panel down, to find three or four capacitors burnt to pieces, and the PCB severely damaged - plus all the rest were blackened.

well thanks very much for the info...Its saved me a lot of time and money.they must have designed the thing with the notion of" lets hope they throw the set out" "lets hope they buy another one".
