You answered on your own. (lol)If its suppose to be a standby 12 volt supply then whats the top voltage to be there?? 12 VOLTS!!! The value your looking for is a 12 to 13 volts 1 watt zener diode.. Im thinking your a handi man trying or attemting a repair?? please remember the HI voltage saftey issues, as these sets hold alot of HI voltage even after they are unplugged for a while. Good luck

You can Swap them if they are of the same rating, must check the wattage. cause the width problem & the power transistor become over heat. you can also use both of them in parallel, if they are ok. your tv live longer.....
HAVE A NICE DAY...

It should be at the back cover, just where the model number is. If you have the TV open, it may also be found inside, maybe on or around the tuner area.

Check its main power regulator section. The output voltage from the SMPS is low.
