i was sat watching tv and all of a sudden my tv goes off or on standby as i believe? the light goes blue and stays blue so i'm trying to turn it on and off and nothing will work, i've changed the batteries in my handset and it still wont turn on or anything:( also its making a noise and the optical digital audio out has a red light on and making a high pitched sound but not loud, when i completely turn off my tv it doesn't make the sound, it sounds like the noise is draining out of the TV! Please can someone reply as soon as possible with an answer to my problem or someone that can help with my problem? thanks Callum
