I have removed the back panel and want to test the Power Supply "high voltage" going to the backlight module via the 2 wire (blue and white) connector. I am not getting any reading on the 2 wire connector with the TV turned on (sound and faint picture are present). What should this 'high voltage'reading be? Is it a DC or AC voltage? Dave

I have removed the back panel and want to test the Power Supply "high voltage" going to the backlight module via the 2 wire (blue and white) connector. I am not getting any reading on the 2 wire connector with the TV turned on (sound and faint picture are present). I have tested for the 720VAC with both the Main Board connected and disconnected. No voltage. I have checked the fuse on the PowerSupply. If the BackLight module has failed, will this damage the PowerSupply? I am concerned that if I just replace the PS, will it fail again?
