Firstly are you sure that the remote is working? View the end with a mobile phone camera (iPhone selfie camera works) and see if you can see the IR transmitters glowing. Otherwise, perhaps the TV is in V.OPT 0, where it does not respond to IR commands. To resolve this: With the TV at standby/off. On the Beo4, press the POWER (Red Dot) button and LIST together. Then press LIST until OPTION is shown, press GO (centre button), and then press LIST to show V.OPT. Then press 1. The power light on the TV should blink to show that it has been accepted. Now try the remote and see if the TV will respond

Hi Guy...Firstly thanks for replying ! I cannot see anything glowing on the end of the remote...so i think i will go to the B+O shop and get it checked out first....then check your other ideas...I really apreciate your help and will be in touch regarding the outcome..Thanks.

Guy...Whoops yes can see the remote working..  

Just tried your idea and no joy..no flashing red light.and remote goes to radio.

Sounds like it may be a defective power board, had there been any issues prior to the failure, such as screen flicker or stand control problems?

Morning...No problems at all TV has been great..Just wont turn on now.  

Are you able to move the stand using the remote control when the set fails to switch on?

Thanks very much for all the interest and solutions.....I called a B+O Engineer in...and all is sorted now...Thanks again.

Congrats on that. I guess not just I would want to hear what was wrong and how it was sorted! MM
