I played a friends Transformers LE today and noticed the tilting right upper playfield mech has become quite lazy in operation. In coil test the right coil moves the mech quite well but the left coil is pretty weak. I re-seated the coil connector but without my tools I couldn't do much more. Has anyone come across this before? I'm thinking maybe a mushroomed coil plunger, coil stop or sleeve. Any pointers welcome, it looks quite tricky to dismantle. From below the playfield it looks like removing a few nuts will release the whole mech but there's a fragile looking ribbon cable going from it through the backboard to a small pcb.

Is there a guide/instructions anywhere on how to remove the upper right rocking playfield?

Has anyone ever had trouble with ball detection on the rocking upper playfield? I've just shopped a friends LE combo including taking the rocking playfield out, now I've put it back together and the upper playfield isn't scoring during the ironhide mode. Ball is bouncing back and forth, the 3 red leds up the center are lighting but not the 2 side ones, but no scoring. Removing it entails disconnecting the ribbon cable going through the backboard, I'm guessing my issues may stem from there. There are 4 small black semiconductors up the middle too, are these what detect the ball passing over them?

Thanks for the reply, as I suspected, however these aren't detecting anything. Before I removed the mech ball detection was getting a bit flaky, I'm going to remove the mech again ( a fair bit of work, ramps and plastics have to be removed first ) and reseat the ribbon cable on the underside of the mech. Failing that I'll order a new ribbon cable and pray that fixes it. If it's the board I can't imagine how much that would cost, if you can even get one!

Update, seems 2 of the traces/connections on the end of the ribbon cable got pushed back when inserting into the little connection board shown in the photo above. I managed to straighten them and reinsert, all working now.

Yes there are 2, one under the flat section of the left ramp ( a few inches after the steel ramp ends ), and one behind the starscream round plastic.

There's a 1" x 3" piece of mylar from the scoop to the drop target on the borrowed combo I have here.

I didn't realise there was a topper?
