    Hey folks I just bought a pair of NIB pins. So far love the games but I had a heck of a time getting one of them level.
    After a lot of trial and error, it appears as if my PF is warped/twisted.

    I can fix it by doing 2 things:

    - Adding 3 washers (per screw) to the left rear PF pivot/bracket. So it lifts the PF support bracket off of the PF a bit in the back left.
    - I can push down on top of the front left pf "hook" (the part the hooks the lockdown support) with my thumb.

    By doing this, the PF is level.

    Thanks.

    Thanks for the advice folks.
    Sent the distributor an email tonight.
    I have been playing with the PF to see what is going on. PF seems to be ok until the weight shifts from the front rails to the back rails (as you slide it back). When the PF is pulled out a bit and the weight is on the front rails, it seems ok. It seems to not be warped because there is enough weight on the front to cause it to sit flush. It is when you slide it back and the pivot brackets at the back take the weight that the front left pops up a bit.

    The biggest issue right now believe it or not, is reinstalling the glass. The left apron is up enough that it is causing some friction. This causes me to have to really force the glass back on. This is a bit scary.

    I've attached some pics. The pic of the front rails is when the pivot brackets at the rear are carrying the weight.

    Thanks

    Update. The pics were from a few hours ago. I spent at least an hour just inspecting whatever I could to see if I could fix this.

    Now it seems to be better. Did the constant pulling/pushing of the PF have an effect???
    The left front still doesn't sit flush but somehow it has gotten better. I'd say the gap is now about half of what is shown in the pics. Weird.

    Quoted from Yoko2una:

    Just to confirm whether this may be an assembly or alignment issue, have you taken a straight edge to the PF, both vertically and horizontally? There were legit issues with some recent machines that had real warped playfields. If your problems are disappearing after jostling around, that doesn’t sound like a warped PF.
    This is sounding a lot more like the apron hooks not seating properly in the bracket under the lock bar (potentially in one of your pics) and not of a true warped PF as the title suggests. Instead you just got to ensure those hooks fully seat. But please bust out the straight edge and verify because you wouldn’t be the first with a warped PF if actually true.

    I can check that later today. The problems disappear if I force the left rear up and force the front left down (by pressing it down with my thumb). So the PF appears to be "twisted". It seems as if the back half of the PF is twisted slightly counter clockwise while the front is twisted slightly clockwise.

    I've owned over 25 pins and this is the first time I've ever run into this issue. I just cannot get it level. I can get the cabinet perfectly level but not the PF. I am at a point where I can get it close. Hopefully Stern has some thoughts. I want to just grab my big pliers and bend the right hook upwards which might let the entire PF sit lower but I don't want to do anything to void the warranty until I hear back from Stern. Lowering the PF doesn't fix the issue with the PF but it will help with the apron causing to make the glass removal/installation a pain.

    Quoted from CrazyLevi:

    Agree strongly.
    Have you noticed any issues while playing that lead you to believe the playfield is warped?
    If you don’t, I’d stop looking for a problem, and just play and enjoy your machine.

    I had issues at first with ball holds because I just quickly levelled the cab. With every pin I've owned I could get by with levelling the cabinet and that would get the PF either perfect or very very close. I took off the glass to further level the PF when I noticed this issue.
    The most noticeable effect was the apron causing the glass not to be able to slide easily. Getting the glass on became a bit scary. One wrong push at the wrong angle and I fear that it would shatter. Again, I can get the levelling somewhat close and if this were a used machine I'd figure out a way to get the front of the PF to sit a hair lower so that I can get the glass on/off more easily.

    Thanks.

    So I tried something this morning and it made things much better. I added 2 spacers under the right front bracket.
    That lowered the PF by that amount. So now the glass moves much more easily....AND...it is much closer to level. Both brackets now sit flush. It is close enough for me to be happy.
