NEED HELP! TX4000 problem! Please check this

[Krypto]

So. Here is my story and im sorry for my bad english:

I ordered my metal dance platform (tx4000) from play-asia, on 09. Dec, 2005 and it cames to me on Dec 15, 2005. First it was great but yesterday when i was playing suddenly my down, left, right and select button stopped to respond. I unplugged my mat from my computer and restart it and then restart stepmania. But the same broblem was on again. Then I went to the "test input" section and I noticed that all my arrows respond when the up arrow was pressed down. But as soon as I dont press the up arrow the other arrows dont respond, so i must keep the up arrow pressed down whole the time if I want to press other arrows and that`s very annoying and it makes the playing of game impossible I have tried to solve this broblem, but nothing helps. Please tell me some solutions if you know.

Are you sure that you plugged the cable to the pad not upside down?

[mouseish]

either the cable's upside down or the control box is shot.

[Krypto]

What do you mean when you say that the cable is upside down? It only fits in one position to the pad, you cannot put it wrong way?

Have you forget me or dont you know help for my problem?

[Snouman]

The fact is that I dont know what will work to your problem. Changing control box might help. My tx4000 hasn't had any problems.

Sounds similar to the problem im having, My pad doesn't allow me to stand on the left arrow and hit the right arrow. Right arrow wont register. But if im not standing on the left, its fine.

I already solve the problem... black wires from the up arrow were cut off... Working perfectly
