I have had this TV a year and a month ago it will power up for maybe 5 seconds, before the pic comes on, then click and shut off leaving the red light at bottom blinking. I can manually press the power button to stop the blinking then press the power to turn it on again. I sometimes get it powered up the first try sometimes it takes 4 0r 5. I see nothing in the manual that addresses this issue. Anyone had similar problems or can help me?
