According to my diagram, R331 should be 5.6k. Actually, if it's 1k, there should be no problem (unless someone changed it in the past to try to cure the real problem).
It appears to be stock. And I measured it in circuit. I’ll lift a pin and see what it says...
Move the test lead to pin 6 and measure the voltage there. If
it is logic HIGH, the multivibrator should run; logic LOW inhibits the multivibrator.
