So how about this? Once I disconnect the SC board, I get 8 blinks. If I use the troubleshooting flowchart for 8 blinks (attached), it leads me to the D board. TV still shuts down with the SS connectors and power connector removed and a jumper on P12. The Vsus voltage exists at pin 1 of P11.
What do the experienced troubleshooters think about the likelihood of a faulty D board being the root cause? It seems that something about this fault may be causing the TV to report a code that doesn't jive with the standard troubleshooting wisdom...
- I think the power board is OK as power is always where it is indicated that it should be.
- New/different SS board and new SC board do not fix or change the problem.
- Disconnecting the SC board (and by extension the buffers?) does not let the TV stay running, so I THINK the buffers may not be the likely cause...
Thanks!
