Re: How to troubleshoot a BN44-00424A
"The GND pin 10 /9 has "Vamp" in the 4th column to the right on the pcb"
The even column pin 10 is 'GND', the ODD column pin 9 is 'VAMP' so no way you can have 18.9VDC on pin 10 GND.
Same for BL-ON, no way you can have 18.9V on that pin, etc.
Vamp reading of about 17~19VDC is fine, it is not tightly regulated power supply for the Amplifier circuit.
After looking at your reports, I see why your report is not right, I was looking at your chart as the STBY column as the EVEN column, and the PWR ON as the ODD column, but no matter since the GND pin 10 shows 18.9V which cannot be right any way.
You have standby column and ON column, you need the EVEN number column whne it is in standby and when TV is ON column, same for the ODD number column, so the readout will have FOUR columns total.
