No, if you mean the "heartbeat monitor" LED on the T-CON, it doens't light up at all at any time, looks like the board it 100% dead (either by itself or due to lack of some power, I don't know what PS voltages it depends on)

Yeah, well I have the back off a 50c451 and with x y disconnected and ribbons also disconnected. I get a nice steady 1 sec heartbeat.

Even with all ribbons removed from the Logic Ctrl board but with main connected to power and the power connected to the logic board it still gives a steady 1 sec blink.

How about posting some pictures.

And that guide i put up tells you the voltage and pins at the logic board. Have you looked at it?

Yes I will try to take pics next time I open it up (I need someone to help me bring it up to the work bench )and also take voltages for Std-by, etc...

Thanks

If you mean the PDF you pointed to, yes! I downloaded it and saved it to have it handy later tonight if I have the chance to bring the TV to the work bench
