Symptom - Tv would display splash screen and shut down a few seconds later.
Heating the inverter near the octocouplers would allow it to come on and function properly.
Replacing Q1970 (transistor C3200) fixed it. The transistor tested open E-C when finally removed from the circuit.
This inverter is in at least one other set so maybe this will help somebody else down the line.
