Re: Panasonic Plasma TC-P50GT30 7 blinks SC board shorted

New member here. Have 2008 Panasonic th-c50hd18 with 7 blinking lights. Have read a lot of post and am starting with SC board. Have new SC board(TNPA4393) from ShopJimmy and want to test before attaching SD/SU boards. This model doesn't have SC50 jumper. other than disconnecting from SD/SU board and removing ground screws, what else do I need to do to isolate the SC board.
