CAREFULLY !!! and with a steady hand short correct row and column and Bob's your uncle. I found one for about 75$ on the fleabay but sincerely I would rather do the board mod rather than spending 75$ on a piece of paper waiting to go bad again soon. Does anyone has one to sell ? Maybe Feedbackloop :) --- End quote --- You can check to see if one of the row/column lines is shorted to ground on your keypad foil. If so, you can try to fix this by peeling away the ground plane from the affected track where it bends. |

Yes, I tried but looks like something else has gone crazy on the keypad and I gave up the fight. Anyhow I found this 75$ but it is the board not the foil one - https://www.ebay.com/itm/231220191481 . I pulled the trigger and got one, I hope is not just the board but it comes with a connector and cable. Will let you know. BTW, for those that want some probes that look like the originals, they are pretty close .. at least in looks and promised performance of 300Mhz; so they should do it OK. One advantage, they don't have the insane price as the original ones - see here https://www.ebay.com/itm/185411884333 |

I thought that for $75 they have a decent replica of the original. |

I bought a couple of these Staubli Isoprobes (version II i think) which I believe are the same as the original. Can't see them for a good price now though. The Chinese ones look the same as that |

Yes, I will make a good photo once I get it. I dropped them a message and they did confirm that it comes with connector and flat flex cable. Looks like is the same guy that is behind http://scopemeterrepair.com/ |
