Yes, be sure that you are not inadvertently heating parts beyond Q25, D22 and D23. The voltages you show would lead me to believe Q25 might be the problem. The 0.03 volts at the collector of Q25 is very low causing me to think the switching transistor Q25 is shorted collector to emitter or Q25 is not getting the proper voltage from the emitter connection at Q13. Normally, one would expect a saturated collector voltage of greater than 1.0 volts (Q25 transistor switched on) above ground (emitter). I am assuming that Q25 provides the ground connection for Q13 to switch the relay to the "on" state. But, the schematic doesn't really show what is happening with Q13 (Q13 is drawn as an op-amp). You should look at the voltage at R153 (Q13 side) to verify the voltage from Q13 is there. If Q25 has shorted, the voltage drop across R153 will be on the order of several volts. If there is no voltage on the Q13 side of R153, then look to Q13 as the problem. Also, there are multiple connections to the emitter of Q13 ... those also could be causing your problem.
