Looking for replacement clock LCD
I'm trying to find a replacement LCD for a Toro Vision 2 irrigation
controller. I tried to purchase one through Toro, but they won't sell it to me. It appears to be a fairly generic clock display. It has 4 full digits w/ colon in the middle, AM and PM to the right of the digits, and along the bottom are the days. It has legs attached to it, 12 along the top and 12 along the bottom at 0.1 inch separation. It appears that the first, 6th, 7th, and 12th pins in each row serve no electrical function, as they're cut shorter than the others and do not contact the PCB. The only writing on this LCD is the number 2391 on the back. Here's an attempt to draw the display (it looks reasonably correct if all the characters are the same width): o o o o o o o o o o o o ------------------------------- | | | #### #### #### #### | | # # # # # # # # # AM | | #### #### #### #### | | # # # # # # # # # PM | | #### #### #### #### | | | | SUN MON TUE WED THU FRI SAT | ------------------------------- o o o o o o o o o o o o Any help would be greatly appreciated! |

It's probably a custom made part, but you could probably adapt a generic surplus LCD panel to work. What's wrong with the existing one, is it physically cracked? |

The one I have has some segments that quit working. Makes it difficult to tell a 7 from a 1, etc. I swapped the display from a good unit to verify that it was the display that was at fault as opposed to the driving circtuitry. I also suspect that it might be a proprietary part, but I'm hoping to find that I'm wrong! |

Those occasionally get contaminated or misaligned and cause dead segments. It's pretty rare for the display panel itself to fail unless the driver put out DC and caused electrolosis damage, could happen though. |

No, it just has all the pins attached along the edges of the panel. They're sort of crimped on, then covered with a clear layer of what appears to be some type of hard conformal coating. I've noticed that sometimes I can get a bad segment to come on by tweaking the display a little, but only while applying some force. It appears to be bad connections, probably where the pins connect to the panel. The pins are soldered into the PCB, so I know the problem's not there. |

Bummer, sounds like your initial diagnosis of a bad display is definitly correct, it'd be worth checking surplus places like All Electronics, HSC, Alltronics, and a number of similar places. |

Have you tried Toro's PartsViewer? https://lookup2.toro.com/partdex/default.cfm If so, is the clock module considered to be a serviceable part, or do Toro expect you to replace the entire PCB? - Franc Zabkar -- Please remove one 's' from my address when replying by email. |

I imagine this model is obsolete. The guy at the irrigation supply shop I went to looked up the controller in an older parts book, and the display was a serviceable part early on (Toro part #35-9488). When he tried to order one for me, he was told that it was no longer available. But he started checking around and found out that some of the current Toro controllers are still using the same display, according to the newer parts breakdowns. So it seems like Toro should be able to sell one. I think they would rather I bought a whole new controller instead! |

Yeah, I'll keep checking around and see what I can find. If the display didn't need to have the days on it, I would probably be able to adapt a genereic display without too much difficulty. However, those days are very important to the operation of the controller, at least to get it to water when it should! |
