didn't really want to go down the easy route of just changing the board, do like component level, but it was a rush job for a friend with kids on his case, must a admit it's only the second samsung i've had with this fault. didn't have schematic, tested the usual diodes transistor, but all ok out of circuit, could have used ebay, emos pretty good for me so far.oh the board was a bn44-00264c thanks
regards
