Hl Al, yes I did ask about the Samsung TV. I haven't had a chance to strip it down again yet as there are mega loads of screws to undo and it weighs a ton. I replaced one of the capacitors which had blown as I assumed that this was the problem but there must be another one blown somewhere else on the board, either that or there may be a dry joint on one of the panels but I'll have to get a stronger magnifying glass to check it out.
Thanks Stoofur, Wak and AlBags for all the answers, here's hoping I get it sorted today,
