Thermistor is for degauss.
Most solid state sets bleed off HV fast so no clue there.
Find on/off relay, USUALLY black, rectangle, 4 pins, near the DGS
thermistor. Cant see in pix. Check it for bad cons.
Quick tests: Check DC at STR. The big resistor above it should
have 150v one side apx 130 on other.
Check hoz drive xformr primary abt 75V sec abt 0V.
Check hoz out, case ( collector) abt 130V
Get back with results...........
