Hello! New to forum ...
Samsung no pic already tried diff power board
I have a Samsung PN43F4500AF, no picture when you turn it on, but if you move the joy stick on the power button the light n the front will flash like it's going through menus.
I checked voltage on the original power board at the VS, VA andVSC test points and all were very low etc 13.8 volts, .175 and .014 respectively.
I bought a supposedly good used power board, installed it and get the same readings.
At the VS test port when you power it up and turn it on it starts out showing 205 volts and then drops down little by little until you're at 13 volts.
I have a blinking led light on the power board that blinks steady at about five second intervals
Any insight or help is greatly appreciated!
