On turn on No pix but sound Turned off with remote then on again now no sound Tried reset procedure no joy there either All that happens the red light can be turned on & off. The set is barely 3yrs old....no spares or firmware are available .....zero support. Business model get the customer to buy a new one! These TVs are generic and are sold by a number lower cost end sellers. Diagnosed the problem to the main logic board and have found a 65" board on fleabay made for Thorn. Apparently it's load with smart TV software which included WiFi module The only missing thing are two cables control & power lead Has anyone got a photo of the cables. However, JVC 55" curved screen model LT55N776A has the same arrangement.
