In order to resolve I had to reset my TV to factory settings.
Last week we was checking a show using the SMART TV we lost the the power. From that time every time i try to access the TOU.TV application we get the first screen but the circle loading turn and nothing happen.
I try to disconnect the unit, reset the unit, re-install the unitial set-up nothing change.
if i try to access any other application every thing work.
i hope you have a solution for that problem.
