Default Re: Panasonic TX-P50STW50 Power Supply no 5V (was clicking)

The diode is not shorted, but it is hard to say if it is reversed or not, use some alcohol to clean the top of the diode so you can see the letters or marks. in diode mode it should read around .6xx volts one way only. the cathode would be the negative lead of the meter when it reads .6xx v
You don't indicate which way your probes were so the arrows don't mean much. was the negative probe (black) at the point of the arrow?
