Hi I've bought a 42PFL6067K/12 television this month and I have updated the tv to the latest firmware (150.082).
When I turn on the tv, it shows the previously tv channel, however if I change the tv channel the screen goes black. Sound can be heard and the menu can be seen. Even if I change the source to an hdmi the screen remains black.
By turning on the tv and selecting the hdmi the television works, but changing the tv channel makes the screen black.
