hi!
I'm having problems with my LG plazma 50PS300.
I'm suspecting the power supply board EAY60716801.
When I power it on it makes 2 clicks and goes to stand by.
When I turn it on (button or remote) the LED blinks 6 times blue and then turns red.
The coil marked on the picture starts to buzz.
I mesured the voltages and they are all 0 except stby5v which is 5V.
Tried with all board connected to PS and all boards disconnected, its the same.
I also tested all fuses and they are ok.Tested all diodes and i think they are ok (not open or shorted). Also I tried to change the voltage regulator IC301 (STRW6252S) and the red capasitor marked on the picture.
Nothing changed. Please advise me what to do next.
If you need more info please tell and I will provide.
Sorry for my English, not my native language.
thanx
