How have you confirmed the the cable repair is good ?
Can you provide a bit more information about the problem ?
For example, does channel 146 appear normal in terms of displaying the live broadcast video and audio on the TV ?
Can you pause/resume and show subtitles on channel 146?
Does the unit respond to other operations from the remote such as accessing existing recordings using ‘Media’ or searching the EPG and setting recordings ?
Can you navigate to the setup options via the ‘Menu’ button ?
