Hello guys,
I got the broken plasma LG from ma friend to take a look at.
The tv cant start. If i plug in the cable i can hear the relais klicking several times. It tries to start and klicks again after a few seconds. No picture.
Removed the above right connector. Still the same error.
I found out, that its a power supply Problem.
I measured a few things with the multimeter. Did also a few tests with m_on and rl_on connected to the stby pins like described here.

I cant measure the 190v or more. I can hear one relais clicking. After moving the m_on switch, i hear the other relais, but no Output on vs. And then the same thing starts as described above. One relais starts to klick and after a few seconds the other. Again and again.
Couldnt recognize any bad capacitors. Fuses are good, Running out of ideas.
This is the power supply
