Hi everyone,
I've read over most just about all of the 7-blinking light posts on here and they have been very helpful. Long story short, I isolated the SC-board to be problematic so I replaced that. Now when I perform the SU/SD-board isolation test by jumping the SC50 connector, the TV does not shut off and I see the Green light on the SC-board. It does make a kind of buzzing noise, but it looks to be OK.
With this in mind, I ordered replacement SU and SD boards. After connecting them, I still got the 7 blinking lights. I tried every combo of their SU/SD boards and mine and got the same issue. Even though I tested all of the ribbon connectors for shorts and found none, I still decided to order a new set of SU/SD boards since they're all refurbed nowadays and maybe I got unlucky, however the new SU and SD boards I received today gave the same issue.
So this is where I'm stuck at the moment, it would seem like there is something else wrong with the TV apart from the SU/SD boards. Anyone have any ideas? I performed the SC50 isolation test today and the SC-board is still good.
Thanks in advance. I really love this Panny plasma and I don't want to let it go!
