Quoted from alchy999:Willing to try any other tests you guys have. Is it possible the power transisitor q90 has a broken track somewhere?
You could 'ground' the metal tab of Q91 to trigger Q90.
If this activates the hi-power coil, it could indicate that Q91 is faulty.
If it doesn't activate the coil, a broken trace is a possibility.
Quoted from alchy999:When in flipper test the power does nothing but the hold raises the flipper as normal.
Quoted from alchy999:replaced the Tip36c Q90
After you replaced Q90, did you perform this test again and what was the outcome ?
Trying to find out this is a coil drive problem, an opto switch problem or both.
I meant the test T.12 in the menu.
Grounding the transistors as you did gives the correct response. (Q90 nothing, Q91 normal flip and Q92 slow to hold)
Quoted from alchy999:the right power does nothing
Quoted from zaza:Trying to find out this is a coil drive problem, an opto switch problem or both.
It looks like it is the 3rd option
