1) unresponsive remote control.... yet again,couldn't turn off the tv night before last,had to remove the power cord from the set,wait a bout 30 sec,reconnect & wait for it to reboot,then turn off with the remote control

2) often when using the remote control to select an input by pressing the button on the top left of the remote,either it takes 2-3 presses before responding,or the input selection quickly flashes up & then disappears,other times it sticks on hdmi1 when I want hdmi2, this process has frozen the tv in the past,

almost 1yr on & these problems persist. 

I've done a factory reset at least once in the  past year
