content: Quote from: jonpaul on August 18, 2021, 12:57:03 pmWhat upgrade issue? Firmware when meter fails when you upgrade too old into too new firmware? Solution for that was simple, just don't upgrade straight into the latest FW if original FW is below certain version.QuoteIf it's not about firmware upgrade problem, then why just you don't upgrade the firmware and see if what Keysight says is true?

content: Just rereading thisNOTICE: Upgrading the 34460A and 34461A with firmware revision 1.xx to revision 3.0 or greater34460A and 34461A DMMs with firmware revision 1.08, 1.09, or 1.10 currently installed must first be upgraded to revision 2.17 (see the ‘Previous Versions’ tab), and then upgraded to revision 3.0 or greater. Upgrades to 3.0 or greater (from 1.xx) cannot be done directly.If attempted, the DMM can be recovered by updating the firmware (to 2.17) from the front panel USB port. Select ‘Front Panel’ on the Firmware Update Utility to create the appropriate folder on a USB thumb drive.I am going to try that and anyway return to Keysight for other ssues, intermittent dead display.Jon

If the display appears dead, try shining a bright flashlight into it at an oblique angle and see if anything shows up. It may simply have a failed backlight, in which case the repair ought to be straightforward whether or not the warranty is valid.

content: bdunham7,indeed the display goes 100% dead, black LCD is OFF, its not just the backlight.Its more and more intermittent and come back for a while if you slap the case.I now suspect this unit was dropped in the pas, on the top and suffered very high shock impact.Inside everything is perfect and tight mechanically, only one ribbon and one right angle PCB connector, both are fine.I suspect front panel PCB may be at fault, hairline crack in a trace, etc.Keysight service should be able easily to reproduce the dead display and replace the panel.Its out to warranty repair today insured fast freight (at my expense)Predicted turn around time 2-6 weeks.AmicalementJonPS: Keysight Tech support and service dept are 100%, responsive, intelligent, speaking English and USA based!This is in great contrast to the voice robots and time wasting offshore support of many other firms, with lowest level operators and scripted responses.

content: I bought the 70 this summer, it came with the latest firmware, but it didn't have the memory upgrade.On the other hand I got it for free with the web offerhttps://www.keysight.com/fr/en/cmp/promotions/free-memory-upgrade-for-bench-solutions.htmlProof of purchase and the serial number of the device are required.
