MS6000 tv power problem - or rather lack of power problem - any ideas?

I have an MS6000, with motorised stand, looks great, has great picture and sound, that is until this week when the green and red power light went out and has not come on since. I have changed the plug fuse and replaced the remote batteries but all to no avail. I am wondering whether anyone else has experienced this problem and if so if there are any ideas on what I can do. The B&O deserves to retain pride of place at home, with some help hopefully it will.

Thanks in anticipation
