I've had my Sony KD 55x9000h for around 4 years. I recently went away for a month, so I unplugged the TV before leaving.
When I returned, I plugged it in and used the remote to turn it on. It seemed to take longer than usual to display the home screen. I turned it off with the remote. Later when I wanted to watch it, the TV wouldn't start. So I tried the button under the Sony badge. Nothing.
I tried a different power source, unplugged the soundbar and tried all the youtube solutions. Nothing works.
Any suggestions before I get an overpriced serviceman in?
