My high speed playfield flashers aren't working, is there a good place to start looking to troubleshoot?
(Topic ID: 47400)
The other thing to look for is to take a look at the wirewound resistors. they are the large grey resistors that have the white stuff in the middle. A couple of mine had the legs break off right at the connection point to the body of the resistor.
For the flashers they are at a couple of spots under neath the bottom of the playfield. Don't have the specs in front of me to tell you exactly where.

To be sure...do you mean that ALL of the PF flashers stopped working?
What about the 4 flashers in the backbox. They will strobe when you press the flipper buttons with a ball in the shooter lane.
Have you placed the game into coil test to see if they light?

I'm pretty sure the flasher bulbs are daisy-chained so if one bulb goes, the rest behind will as well. I would check bulbs first.

Only if a wire breaks off. A burnt bulb will not cause the rest to not work

Uh oh, someone better tell Clay he's wrong ...
Flash Lamps in Series.
On some games, multiple flash lamps were driven by the same driver transistor, and were wired in series. This means if the “first” bulb in the chain burns out, power will be cut to the second flasher bulb. Keep this in mind when you see a pair of flashers that are not working, which are next to each other. Flash lamps in series do last longer though, because the overall power to the lamps is lower (compared to wiring them in parallel).

I've had my flashers burn out before in my hs, and the others were fine.
But my hs is a hot mess of op wiring hacks still, so that could be one of em. Been slowly working on the fixes. I will check it out! If I am wrong, my apologies.

I had the exact problem with the flashers (radar detector), there are two strings and only one was working It was a blown bulb. so the above proved to be true, its was also the same for the flashers
above the ball captures, one bulb out and neither will light
Some early system 11 and system 7 games had two flashers wired in series. If one failed, the other would not light. The flashers in Hyperball and in the HS backbox are definitely like that. There are more, but I don't recall exactly where.

Well it was just bulbs, I had four that passed the visual test but were bad. The rear flasher doesnt work but its not the bulb, also does anybody have a pic of that area, is there supposed to be a cover on that one, if so mine is missing.

Congrats on the 'fix'.
Which rear flasher? The two in the back playfield corners?

Check page number 34 in the manual (page 40 of the .pdf file) for a diagram and list of the flashers. The two at the top corners, shown as #22 in the diagram, do not have plastic covers per se, but the one in the upper-right corner is actually hidden under a playfield plastic - at least on my High Speed.
