The second transistor .... 1.8-1.71 looks a little suspicious.
I would remove/desolder this transistor, and with it removed from the circuit, check the collector voltage, and also the base voltage to see if they corrected to more of an expected value.
If the collector voltage on the circuit board measures somewhere around 5.2, then it might be worthwhile to try a new replacement transistor.
Sometimes, these transistors are installed as matched pairs, so you might want to also replace the primary transistor .... just guessing about that.
Can you provide a photo of the two transistors in question?
