Typical, just after posting and re-reading for the 4th time I think I understand, this is a PWM signal from the main IC?
So test by injecting 12V in to the bus and see if the rest of the TV is working or just replace the A board?
Sorry, typing and thinking at the same time..

Panasonic TH-55FX600 - No standby LED
Got a TH-55FX600 that is showing no signs of life.
Outputs from the P board look good, but no 12V on the A board.
Very similar to [URL]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-tvs-and-video-sources/110001-panasonic-tx-65fx623e-identidy-ic[/URL] but where Tibd has 3.3v on the EN pin I have nothing, no voltage at all.
Looking at the diagram for the IC I can see the enable is W_OPCTRL9, but I can't find a source for this, can anyone help please?
