Hi,
I have sony w800d tv and i recently replaced it's tcon board because I was having 5 times red light blinking issue. But after 3 days my tv started to blink again but when i turn off the tv then it's not turning on not even the indication light. But when i disconnect the tcon board from main board the tv turn on and when ie my old tcon board, it is also turning on but red light blinking as usual but when I connect new tcon board it is not turning on. Then removed the tcon board and turned on the tv then connect the tcon board after turning on the tv the display turns on and everything is working fine but when i turn off the tv it's not turning on. Help me guys.
