Re: Samsung PN60E6500EF blinking red light

Hi All,

My SMPS relay keeps clicking on and off randomly. When it's ON, voltages are correct and I get a fine image as long as it stays ON long enough to see it. I troubleshooted this board a year ago and worked fine for a while. I changed 2 FET's and the main fuse at that time.

I didn't find the schematic for this board so I am not sure what could cause this problem. Over current protection? Bad standby cap? Heat didn't help. I checked all soldering and retouched them. Changed a few caps coming in the rebuild...
