Hi all,
After a while of using my other DMM's only, I've turned on the U1253A for a quick measurement today, and guess what... the OLED display seems to be problematic. In the past I've used the low brightness setting and the display was just fine, now its barely visible at this setting. Medium is now at best what low used to be, and there's hardly any difference between the medium and high settings.
I've tried replacing the battery (or actually running it off the lab PS, and it stays the same). It is usable as is when I place it on the medium setting, but its just no as good when the bench light is on and I'm trying to read the display.
The device isn't under warranty, I've purchased it in the Grainger deal >3 years ago, and as Keysight have told me by phone today, its still registered under their name with a purchase date of somewhere in 2009 (which makes no difference since the warranty is limited to 3 years). I'm still waiting on a reply from Keysight about replacement cost (they say they don't repair such small instrument, and instead offer a replacement).
In the meantime I was hoping to get some ideas from you guys:
1 - Anyone ran across this problem and knows how to fix it?
2 - If not, is there anything that's an immediate suspect in this case?
If replacement cost is too high (and I suspect it will be), I wouldn't mind giving it a try.
