No video and can't check audio without video to switch between inputs.
TV was gifted with "if you fix it, it's yours"
Followed Toshiba Smart Flow and it seems to point to syscon on main board
Power supply 01-PK101V10001 shows following readouts
Pin readouts on PS at P802 expected and (actual)

8. 12 V> (no reading)
9. 12V (Panel Pwr.)> (no reading)
10. 5V>** (no wire in connector but 5V without connector in place) ** indicates standby
11. 5V>** (5V)
12. 5V>** (5V)
13. Pwr. On (Enable) 4.0V< (.07)
14. AC Det (PWR Good) .07V> (5 V without connector - .04V with connector)
15. Dim 1.3 to 3.3V< (.02V)
16. BL On 5V< (.01V)
Notably, when I disconnect pwr board from main board and inverter, and short pin #13 to 5V the readings expected as 24V is only 16V and expected 12V is only around 7V.
If syscon on main board were the issue, I still have the problem with reduced 24 and 12V even without the main.
I can't find any schematics for the boards.
I have limited skills and a voltmeter and a brain if any of that helps.
