I have used these forums previously to help troubleshoot and repair capacitors/replace boards on LCD sets, however just was asked to look at my first plasma. I've done some reading about the differences in boards but the testing of the voltages/y vs. z boards confuses me.
The TV clicks when trying to power on. The screen will flash gray a couple times then the set shuts down. I've unplugged both y and z boards and turned on the TV to only exhibit the same behavior. I've checked all capacitors for failure and there is none visible. I've checked the 3 white resistors in the upper right of the board and they all measure 10.4 ohms stable. I have also removed the board to check for broken solder points and nothing jumped out at me there either.
Beyond that I'm not sure what or how to check next. I do see the VA and VS test points but not sure how to test (from point to ground to test voltage?).
Thank you in advance.
