BT installed a you view box last week. 6 hours later it froze . BT advised factory reset but this hasnt sorted the issue. After about 10 minutes of having the tv on the screen will make a noise and then goes black. The you view box button will stay blue and the remote cant switch it off. The box then has to be switched off from the back. The box still records prigrammes but when playing back the audio description is on (even though its not set). Bt are coming to take a look on Saturday but wondered if anyone else has experienced the same issues - BT say if it turns out to be a problem here then I'll have to pay £120! All v frustrating .
