    Doctor who sol/flasher 19 5x3 right Q38 works in test for about 10 minutes than it sticks on ? when I go through the flasher test mode the 5x3 right will light slightly as i test
    20-jet bumpers/Dr5- Q36,
    22-(H) Dr2-Q30
    23-(O) Dr6-Q34
    06-2nd chance logo flasher

    once it lights the only way it goes out is unplug J 126 ?

    testing the Q38 and Q 37 seems to test ok ?

    I thought it might be heat related but I just turned it on after I typed this and its coming on right away so maybe its not that ?

    the Tip102 Q38 was replaced its got a different c0505 number and the original are 9A222 ?

    I have the J113 unplugged and that didn't make a difference either

    any help would be appreciated!

    Glad you got your issue fixed. It was a learning lesson for me. When I first read it, I admit to not knowing what language you were speaking. I went through my manual to look for similar letters and numbers. I found you were talking about a specific transistor Q38. I then went through the test pages to see what tests you were referencing. I was not able to see where on the play field a right 5x3 would be. I am assuming when a solenoid activates in a test or in the game, a light bulb (flasher) illuminates. I looked at the bulb sets. I saw two 6 bulb sets left and right. I saw the bulb set (red squares) that lights up in front of the MPF (is that a 5x3?). Sorry for the beginner questions.
