I ordered a Logic Board as am hoping that will fix it Since no Pic test pattern based on the above test video .

I also can't determine a way to verify the Ymain beside that it present the correct VSCAN

Installed new Logic board and No change , Still Black non glowing Plasma screen , Every thing else is functioning ( SMPS, Sound , Power On / Off )

All corresponding Voltage reading including the vscan spot on



Y main spare board on it's way


ANY thought , Is the y main is board responsible to power the plasma screen ..?
