Sanyo tv has lost all channels and won't auto or manual tune
I have a Sanyo LED-42XR10FH which has suddenly lost all channels and won't auto tune or manual tune. Powers on fine, other devices connected work, just no channels. I have tried disconnecting from wall, factory resetting, checked all cords, replaced coaxial but continue to get a no signal message when trying to manual tune. Old tv but has worked perfectly until now.
