Replacing OLED screen on an Agilent U1253A Multimeter

Cut this trace...

Kimmeridgien:
...and solder wire here.

Kimmeridgien:
Sorry, could you be more specific?

Hi all,

My U1253B went dim after 6 years of very light use.
Just wanted to give you a heads up that this Taobao seller is selling a display for U1273A, U1273B, U1253B and U1253A which worked for me off the shelf. No soldering, cutting, etc. needed. Pretty pricy, but if you just want to get done with it quickly, I can recommend:

https://parcelup.com/shop/item.php?id=623769294078

My tips:

1.  Before putting the whole case together, the picture was mirrored. After all the screws were in, the issue resolved itself. So if you see a mirrored screen when testing without the case, don't give up.  I don't know why this happened, but didn't really want to spend much time on figuring it out.

2. The rotating knob's position is indicated on the PCB.

3. Make sure you don't snap your battery wires when putting the case together.  I managed to learn this the hard way.  :palm:

And of course, shame on Keysight/Agilent.

Hi all,

I purchase 2 displays from parcelup for U1253A and U1253B I own but unfortunatly, the fixing screws don't match the original display and the screen is mirrored (displays received is not the same as in the picture...).
For the 2 displays, the cost was 124.85EUR+32.13eur shipping=156.98eur so I hope to find a way to make my DVM functionnal.
Two options:
1. add the pcb interface to unmirror the display and let the display unfixed with addition of kapton protection on the circuit where the spacers touches the PCB
2. unsolder the display from the PCB I received and solder it on original Agilent PCB as described in Markus Coneheads.de blog:

The second option might be the best but I am not sure the display is fully compatible (number of pins and pitch seems to be the same) and not sure I can unglue the display easily from the PCB.
I will inform you which option I choose! Just a first feedback to inform you that parcelup products are not reliable! It worked for eeffpe but not for me  :(

Cheers

Happy new year!
