Samsung Plasma modelnr: s42AX - YB04
Hello,
The screen on my samsung television stopped working but the audio still works. After reading information from this website i've openend the backpanel and searched for the problem. After checking the Va Vsc VS and Ve values i noticed that there was no Vsc value. So i checked the Y-Main board and there where some blown capacitators. I bought new cappacitators with the same specifactions and replaced them on the Y-Main. Unfortunately there is still no screen on the television. So i checked the Vsc again and the values on my multimeter is jumping all over the place.
What i've done to find the problem:
Ive also tried to meassure the Va value going to the y-main but im not getting any value, on other points im getting 205Volt. The power supply makes a click sound when turning on the television, and there is some buzzing sound from the coils on the power supply.
Whats the next step to make my television work again?
Any advice greatly appreciated.

What i've done to find the problem:
- -Ive checked the bufferboard for shorts, but the bufferboard seems okay,
- -Meassured the powersupply on the testpoints
- -Replaced Cappacitators on y-main board
