I realise that the posting I am replying to is over 2 years old but I found it only yesterday when looking for a solution to a problem that I've now fixed, so perhaps someone else will end up here after me.
I have a Sony Trinitron and thought it had packed up. I was just about to buy a new TV when I found the instructions, (if all else fails, etc) and realised that I must have switched off the TV at the plug when it was in standby mode.
It's working fine now. Try:
- Pressing the Main Power switch on the TV
- If the red standby indicator is on but you have a black screen, press any programme number on your remote control or the button on your remote control that switches the TV from standby to fully on.
