content: Keysight or should I say...AgilentU1273AX is possibly the best meter I will ever have, it works in the ludicrously cold weather and has an awesome bluetooth feature butwhat's the point when it's rendered useless after a few years of hardly touching itI'm not sure.(Yes I have tried to get spare parts to no avail. This is on full brightness and there are just a few bright spots on the screen and even so they're very dim)

content: Quote from: swixo on April 19, 2018, 02:54:34 amNope it's more than 3 years old but... you would expect a DMM to last a long time right?I tried to ask if they would fix it but they said no. I asked if i could get parts and they said no either

content: Is every pixel that dim?Or are just the main pixels worn out?If everything is very dim, there might be a problem with the driving circuit. The display itself may be fine.Greetings

content: As far as I know a common problem of Agilent meters. I was in doubt back then if I would buy an oled or LCD version. I bought the LCD. After many years the stand was dead, the display scratched and it looked worn. A friend gave me one with a worn Oled ( U1254) and I used the cabinet for my Agilent U1253, now it looks like new again.It is a shame for a meter at this price, these displays wear this fast.

content: Quote from: hayatepilot on April 19, 2018, 05:58:56 amSome pixels are just a tad brighter, still VERY dim. It was going bad after time and I hardly used it in case I broke the oled display. What does that say about my faith in the productI use my UT61E way more than I do the U1273AXQuote from: PA4TIM on April 19, 2018, 06:43:34 amAll I want is agilent to tell me I can fit U1272 LCD display on it... Letting a expensive DMM go to waste because of a unreadable display is nuts

content: welcome to oled hell. display degradation is a fundamental limitation of the technology. doesn't matter who uses it.best to avoid all oled unless you plan to dispose of it every few years and buy a new one like a cellphone.

content: Quote from: DiddlyJackSquat on April 19, 2018, 08:52:01 amThe normal LCD of a U1272A probably wont work since the oled is a graphic display and the 1272A has a segmented LCD.But there may be a standard (backlit) graphic LCD with the same resolution and interface as the oled. The chances are probably almost zero and it would involve some serious modding and hacking.

content: Quote from: DiddlyJackSquat on April 20, 2018, 07:55:24 pmDisplay itself is the same. It is tab soldered, so not that easy to replace. Cheapest option seem to be taobao, and don't need desoldering from the PCB as it has just bare FPC. <10% of the new meter price is not that expensive IMO.

content: Quote from: wraper on April 20, 2018, 08:04:25 pmIt's still damn freaking expensive however. In the U1273ax case it has pins going off to the driver board
