This morning I have “no signal” showing, was perfectly fine last night. I can receive sound through my surround sound but no pictures. The box appears to be fine as the LED is showing the station or media, etc whatever I press but absolutely nothing on my TV screen. The TV is OK as I can still receive my freeview on it. I have checked all my cables and they appear to be fine too. Could it be my dish although if it were surely I would get no sound either. Stumped!
