thanks for the tip. Also make sure that the screws that hold the board to the panel are nice and tight and don't have any dark marks on them this is one main reason why it shorts the board out
sorry for my english, i have the same tv like the same issue (8 Blinking led).
In the first time my tv had 7 blinking led, i checked the SC card and i found the short in the transistors.
I have changed with kit for SC card the DUT broken and the now my tv has a 8 blinking led.
I saw the VSUS voltage and i noted 200V this is too small because in the schematic the VSUS is 220V.
If I remove the SS card (TNPA5331) and the SS33 flat the led TV is green but the display is black.
I suspect the issue is the SS Card but i have verified the diodes and the all MOS and i dont found any Short .
Please i need your help for found the DUT broken.
You can help me?
I had the same issue. 7 blink shorted SC, then went 8 blink after repair and it was bad SS Q102 for me. Everything connected right including the SC20 ribbon?

yes, I have measured Q102 and it is good, i have verified the body diode.
