Couple DE niggles?

[ronnie63]

Thought I would ask before I go prodding!

Pin is LW3

problem 1 The right flipper is sometimes knocked down when the ball lands on it? It's flipping strong so guessing it's something to do with the hold voltage on the flipper board? Never so anything specific for this in the repair guide?

Problem 2 laser kicker sometimes is weak and fails to kick the ball back out! I'm thinking it could be related to the outlane switch and maybe the speed of the ball relates to when it fails?

Cheers Ronnie

#1 EOS switch contact clean so the voltage holding the flipper up is all it should be?

My TFTC flipper woes "I think" were due to me not taking some of the slop / free play out of the linkage.
If the fuse holders are as crap on all DE, pop the fuses out of the fuse holders and make sure they haven't gone brittle. 2 of the 5 of mine were shot which didn't show til you took a fuse out.
It didn't solve the problem but it wasn't helping either!

EOS? Doesn't LW3 have solid state flippers.

You're right, ignore everything I just said! I thought being '92 it would be much the same hardware, I was wrong!

Thanks guys, yes no EOS on this one. I should really pull the board and check it over, or should I say I will

Just pulled this flipper board out! Only took 4 years lol, I can’t see any damage or cold solder, I need to find out why the right hold current is weak, would the hold fuse have 9 volts on it only when flipper is energised ?

Thanks Ronnie

Weak laser kick could just be adjustment. The plunger needs to hit the ball square on. There is usually a little bit of play in the coil bracket to enable you to adjust. And the switch needs to be adjusted so that it activates the coil at exactly the correct timing. If it activates a bit late or a bit early there is less power. It's a fiddle to get right but a slow motion video may help to see what is happening.

This was over a year ago, so may have remembered wrong, but the flipper board can operate at half power when one side is broken. So... fuses and transistors need checking. Which side? Pull the fuses from one side and see what happens, replace and check the other. Was a fuse holder clip for me when I had the issue on DESW.

Thanks Ashbo yes it was a while ago, it's the right flipper, fuse clips are fine, I did notice the coil was slightly squashed! As in the plastic where the solder lugs are is bent! Also the windings are detached from the plastic sleeve, I can move them left to right! Looks like the playfield has been dropped on the coil in the past, not sure if that would cause the problem?

Thanks Ronnie

Oh yeah, the coils need to pe perfect, or expect problems. A flipper rebuild with new coils will make it feel like a new game

Ok so flippers stripped and checked both coils replaced, the problem has changed! same flipper but at times will fail to flip or it will chatter a couple times then work then repeat the behaviour, I noticed this coil gets warmer than the other? I don't want to randomly replace parts of the flipper board?
