Hi there how did you manage to sort the problem out exactly as I'm having the same problem, I've changed capacitors that had gone now seems like light in the TV not working properly but not sure if that anything to do with it but all its doing is the screen flashing on and off few times then goes back into standby. Please help. Thank you.
