I have a LG 60" plasma TV model 60PH6608.
problem: relay clicking after plugging in the power cable.
The power supply is connected to the z-sus and then to the y-sus.
I unplugged the connection between z-sus and y-sus
--> relay clicks only once and tv stays on (no protection mode)
--> I measured a shortage on the y-sus between vs and gnd.
I continuied checking the voltages from the z-sus to the y-sus.
On the 15V line I only get about 3 volts.
I think the first step is to check, why there is no 15V from z-sus to y-sus.
Where can I start checking the z-sus ? (no visible damages)
