Cannot seem to find whats wrong. When powered up the blue standby light comes on but within 10 seconds or so the blue and orange lights start flashing. I cannot get the tv to do anything else at all. I have tried replacing the av board with no success but there does seem to be a very quiet alarm from the psu board! Nothing is obviously wrong (bulges etc) all i get is the beeping!!! Please help me im going insane!!!
