Here is how to fix the arrows when it cracks, or stops being sensitive...
1.unscrew the screws to get off the metal things that hold the pad down.
2.gather alluminum Foil, and duct tape.
3.duct tape the bottom of the pad where it is cracked (even if its showing onlt on the top, duct tape the bottom!)
4.Now cut alluminum foil to fit the bottom of the arrow, and leave a little room on the sides, so you can tape the foil to the pad.
5.now tape the foil down to the bottom of the arrow
6.tape the arrow horizontally in the middle, so if its breaks, you wont have to tape it up.
7put the arrow back together, and it should work like new, and become extremely sensitive.
SOME THINGS YOU NEED TO KNOW BEFORE AND AFTER DOING THIS...
1. the one pad THAT I KNOW THIS WORKS ON is the TX1000 (my Pad), it may work on yours, but it depends what sensors you have.
2. if the arrow wont stop being sensored as a hit, look at the bottom, and duct tape the foil that got cut off while playing, or that has fallen off, or thw part where the foil is peiling over, and duct tape it down.
3. if it continues to sensor as a hit, you did something wrong when doing it, so peel it off and do it again.
4. this also works with double sided duct tape, just dont tape it to the sides, tape it under the foil.
I call it, the Silver Dance Fix.
Here is an example of it...
you should already know how to solder, just solder like you have been doing your whole life!....
If you Soldered the sensor multiple time, and it still does not wok you are going to have to pull up the dance pad, or strip threw the bottom, and solder a broken wire (my pad is in this state, and trust me its a pain in the ass).
please post how to make dance pads better, or how to fix them like I did in theis thread.
