ISSUE: My Phantom of the Opera left sling switch does not appear working and the coil does not fire

SYMPTOM 1: Left sling coil appears burnt out and warped where arm won't move
SYMPTOM 2: A leaf switch on the left sling was stuck on outside of rubber
SYMPTOM 3: The transistor at CN19 position 6 Q10 has discoloration burn marks and appears to be burnt out

I replaced the coil and fixed the leaf switch position. ❌ I cannot solve for the blown transistor.

TRANSISTOR INFORMATION
- On diagram, CN19 position 6 Q10 transistor, appears to be a 20N10L
- On the transistor label, it appears to actually be a 1L32AC FQP 13N10L
- Transistor testing a good one it says: BJT-NPN 123=ECB hFE=43 Vf=1.73V

TRANSISTOR REPLACEMENT ATTEMPTS
- Closest match appears to be NPN TIP102 TO-220 which transistor tests as BJT-NPN 123=BCE hFE=45 Vf=1.27V
- Issue here appears to be we want "ECB" and not "BCE" <== WHAT IF I PUT IF IN BACKWARDS

If I put the transistor backwards in my transistor tester, I get the correct "ECB". Hmmmmmmmmm

When I did the sibling test, I ran wires to do the test and so I can't tell in this moment if my own testing was in a reverse direction. I made sure the order was correct of the wires but no way to tell up versus down.

The TIP102 transistor as indents on the side where as the originals do not.

I suppose one thing I could do is re-transistor test with wires and ensure i understand the orientation AND THEN if backwards appears to be the way to go then I may try it.

If I confirm I did have the correct orientation, I won't bother to try again because it didn't work in correct orientation and the issue is most likely the original hFE=43 versus hFE=45 is incompatible and/or the original Vf1.73V versus Vf1.27V is incompatible

✅ SOLVED. So IRL540 does work even though a transistor test registers it as a totally different transistor from what is there.

ALSO =======> I didn’t look hard enough for fuse panels, when machine was still not working I looked harder and sure enough a fuse panel with a blown fuse was tucked away into top right of pinhead.

For good record keeping, I am attaching what the transistor test for IRL540 came up as
