Great video - just a word of caution. It seems the 12864G is replaced by the 12864G2 and this module is not compatible - the display uses a different ribbon cable. I just found out the hard way. So, my search for the older 12864G now continues...
I had mine working perfectly. It sat in the cupboard as I was using the fluke which has much better battery life. I turned my Agilent U1273A on and it only beeps. Seems like the OLED has failed as its too dim to read. I hate you Agilent!
Yep. Got one out of the recycling bin. Now i "only" need a replacement oled ;-) Edit: with a SSD1303 ? Which isnt available anywhere ? Edit2: Might go with a SSD1309, seems to be one column shifted, the right/last one appears as first left column. One user on aliex has luckily posted a picture of his xx23B working ... and that shift doesnt really impact the usage...
@@goozlo You can send them an email to see when they will get more. If you can't find any more replacements you will either have to buy an original from Keysight or you can try other displays, like this one, it looks similar but it's a shot in the dark: www.aliexpress.com/item/2-42-inch-yellow-128x64-OLED-display-module-OLED-module-8bit-6800-8080-4-SPI-I2C/32829112939.html
The guy in the forum who figured this display was compatible was using a 1253A, you can try and open it up and see if it identical to yours. My uneducated guess is that it probably is compatible, if it's the same in the 1253A and my 1273AX, they are probably using the same screen on everything OLED in this series.
"These displays will degrade even when you are not using them" - they shouldn't at any reasonable rate? The LG OLEDs out there are rated for 100k hours, and that's on hours, for off there shouldn't be any noticeable degradation unless they're exposed to high heat or UV radiation.
I agree the lifespan was weirdly short, but mine did die and at an alarming rate in the end, and there are several users complaining about unexpectedly low life. Maybe it's not just a matter of the typical OLED degradation caused by usage, maybe there is an underlying chemical process, either caused by the construction method or some sort of contamination on some particular batches. After replacement it has been working fine. Are you sure about that value on modern panels, though? 100k hours sounds almost literally incredible for a regular LED matrix, 100k hours sounds fantastic for OLED, even after adjusting for most pixels not being at full brightness most of their life, but to be honest I haven't been following the latest developments on OLED screens, it should be expected that they have been improving over time.
@@jfaria LG has made huge improvements on theirs, with quite a bit being physical panel improvements, but even more of it being done in software. And Philips (which uses LG's panels) has seemingly almost eliminated it on their TV's, as they use active cooling of the entire panel, which makes a significant difference. There's still a lot of improvement to be made for TV's, as the 100k rating is for SDR, and currently HDR can dramatically drop that because of how much harder the OLEDs are pushed. But for small devices like multimeters OLEDs should have a huge lifespan. I'm not sure why these failed so quickly, I'm guessing you might be right, that it was some kind of production issue or similar problem. Even with the old screens it doesn't make much sense to fail that quickly, especially when not turned on (again unless left in UV or heat). I wish more multimeters would use them. They're so much more readable than the typical LCDs, and I love how they update so quickly. Even the best multimeters with LCD displays seem to be a blurry mess. And of course they're much more flexible as you're not stuck with a fixed number of elements, so you can easily split the screen and display multiple values at once, or just do little things like change the font size when displaying less or more figures.

Yeah, It would be nice if someone found a compatible LCD display to replace the OLED one. On the EEVblog forum there are some alternative solutions, both with some adapted OLED displays and even some plug and play ones, give the latest posts a read: www.eevblog.com/forum/testgear/replacing-oled-screen-on-an-agilent-u1253a-multimeter/250/

That thing is the real deal. Was having problems with mine and oh boy...you really helped me. Put in the bin and bought a new one. GG WP

Hell yeah. That's a great repair. I'm glad what was left of those pins was enough to make it work. Cool!

I would never buy another OLED multimeter from keysight, but one out of the trash is definitely worth repairing.
what tempe do you use at your heat gun and the soldering iron?
I believe both were set to 350°C
@@jfaria I just destroyed my replacement screen and it's not available anymore. That was the end of my agilent

Just search for “2.42 12864” and you should get similar screens like this one.
Is this display compatible with the older 1253B? Yes I’m another sucker who bought this meter also.

Keysight is a shame. Same problema here.
Yeah, if someone made an LCD conversion for these models I would probably buy one.
So do not buy OLED multimeter. Thank you
If I knew they had this problem I would have gone with the U1272A variant.
