This has happened only today to me and I have had the TV for 3 years now however it is really annoying.
It makes the TV totally unwatchable as it turns on and then turns off again before the picture gets chance to load.
I have read some other reviews which makes it seem common in other models but the repair is too specific to the other models and doesn't really relate to my TV.
Has anyone else had a similar experience or can you help before I have to go to the repair man and (probably) have to fork out a small fortune for a repair?
Cheers
