It almost looks like it could be magnetic to me. Is that possible? See the disk on the wheel? Looks like a metal plate to me.That is exactly the type of sensor I was talking about. Now, there should be the light source on the other side of that pulley. It looks like that area is full of cat hair. Take off the sensor, clean it out. Make sure the cat hair in the pulley is cleaned out as well - so the sensor' slight is not blocked. Then try to find the second half of the sensor on the other side of that pulley and clean that too.
Finally, make sure they are well aligned - pointing directly through each other.
Yes, you are right!It almost looks like it could be magnetic to me. Is that possible? See the disk on the wheel? Looks like a metal plate to me.
That lead looks awfully short. I don't see how you will be able to solder it properly. Remember that it needs to be mounted in such a way that is affixed to the heat sink. And you will need new heat sink compound anyway.So likely both the transistor and the diode? I have someone who can possibly test the transistor for me tonight.
Question : should we try soldering back the diode first? Or do you think the transistor has to be dead too?
You guys were bang on. Just bang on. My friend checked the transistor and it's blown. The diode is fine. Transistor is on order, the diode will (hopefully) be reused. He fixes TV's so hopefully soldering will pose no challenge, he didn't seem concerned. This forum is unbelievable... Well I mean you guys.Get them to test the Mosfet also for shorts etc.
Max.
