Question about LG 37LG50 37 in. LCD HDTV
My LG 37LG50 TV wont turn on when I push the power button the red standby light blinks 5 times then the backlight turns on and the standby light turns blue but no picture or sound. I replaced the power board nothing changed put original back in.
Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.
