What did you use for the GND ref for the meter?
When making Voltage measurement in the primary (hot) side of the circuit, you CANNOT use the chassis GND as thge GND ref for your meter.
The negative leg of the main filter cap the GND ref. for the primary side circuit.
For checking the main AC voltage, you will check Line and Neutral.
How about the pictures of the whole back side of the TV?
We also need good clear pictures of the bottom side of the power supply board.
What AC Voltage do you get at the two inner pins of the bridge rectifier?
Was TV worked on by someone else before you? Any history of the TV?

Fuses and the inner pins of the rectifier = 67.8v (using the negative leg of the capacitor).
No history on this tv, sorry.

AC primary on the Bridge, you measure right at the two inner legs of the Bridge.
Primary circuit AFTER bridge you will use the negative leg of the main filter cap.
