Hi,

I noticed that the flasher 31, located under the red dome on the right ramp is stuck on.

This flasher wasn't working anymore, so i did replace the bulb and it stays on all the time.

I checked the manual and saw it's driven by Q31.

I inspected the wires on the socket and followed the cables under the playfield and couldn't find a short or a damaged wire, so my guess is that the transistor (Q31) is bad.

Your advice please ? Should i replace this transistor ? Is there something else you would check or replace on the power driver board ?

Thanks in advance

Hi Cody_chunn,

I"ll try that and report the result, but probably not before sunday.

Thanks a lot.

Hi Pins4me,

The original flasher wasn't working anymore (from staying on all the time i guess) and i replaced it with another 89 flasher. Thanks for the extra info (connectors).

I mesured the voltage on the pins of the j6 connector today.

With the pinball in attract mode, i mesure various voltages between 12,5 and 19,5 on the various pins on the j6 connector, and 0,01 volt on the pin 7 of J6.

So i guess i should replace the tip 122 located on Q31 on the pdb.

Your advices are welcome, thanks in advance.

Tip 122 located at q31 and his diode replaced. Everything is working like it should

Thanks a lot for the help.

The tip 122 was shorted. Both the transistor and the diode were replaced.
