But why not using your (scope) and test the signals from the connector and sees what comes up? Furthermore, some posts earlier you mentioned that your device did not power on anymore. Got it fixed? --- End quote --- For some reason I would like to know what to expect before probing the LCD circuit. My 289 has been powering on all the time. However there is no longer a green light while booting anymore. It seems to be a correlation between the current jack sensing circuit acting up and the green startup light not working. |

I ran into a Fluke 289 that was working perfectly except some problem in the lcd display. Initially the display showed black vertical lines. Typically this happens when flat flex cable glue detaches from the LCD display. I disassembled the display and heated the flat flex and applied some pressure. The black vertical lines disappeared but then I realized that there was another problem too. The display also had evenly spaced vertical lines of missing pixels. Repeated application of heat and pressure didn't resolve this issue. I concluded that one of the 20 pins has developed some sort of bad connection on the main board. Here are before and after heat/pressure treatment pics of the display. |

There's a guy on Ebay somewhere in the US who sells lots of genuine Fluke parts. I haven't seen him selling flat cables or components or things like that. He sells more cases, screens and buttons things like that. He does sell some LCD's though so maybe he would be able to source the cable you need if you messaged him? Worth a shot if it gets your meter running again? |

Thanks Terry01. I'm not skilled enough to change the flat flex cable on the LCD display. May be a replacement LCD would be a better choice if I could find a cheap one ;). Sent from my SAMSUNG-SM-N920A using Tapatalk |

No prob. The guy has normal LCD displays for sale for around £35 for other Fluke modals but I take it the 289's screen will be more expensive? You could shoot him a mail. No harm in asking and if it gets you a working 289 it'll be worth spending a little ££'s on it. If it turns out he can't get you 1 or it's too expensive you won't have lost nothing asking right? Here's his Ebay site. Good luck buddy! http://www.ebay.co.uk/usr/fluke-usa?_trksid=p2053788.m1543.l2754 |
