I have this Philips 42pf9831d/10 when tv is turn on working ok but if you turn tv channel over by the side buttons it switch's the tv of and the red light starts flashing and can not turn tv back on ontill you unplug tv and plug it back in and tv will come back on. if you change channels the red light it will flash 1 red light and then delay and flash quick 4 red lights thank that must be a fault code sounds like mainboard no bad caps in the psu.
