Asset Management Field Network Q&A

Hi, I have a 475 Field communicator and I am having problem using the touchscreen! Weeks ago the display showed a white spot and I can't use the touchscreen on this specific area!

Expert answer: How to fix Emerson 475 Field Communicator display problems

Sadly, display problems happen a lot with the Emerson 475 Field Communicator. I’ve heard about the white spots ruining the touchscreen before.  And we even mentioned this in the 475 Field Communicator review we did here at Visaya.

Sometimes you can’t fix these issues. Many users have commented on the problem, and most of them replaced their Emerson 475 displays to get the touchscreen function back.

However, you may not have to send your Emerson 475 HART Communicator in for maintenance just yet. Have you tried calibrating the display? Because that might work for you.

If you go to the menu, then you’ll see the option to align the Emerson 475 display. To do that, you follow an arrow to touch different parts of the display. If you can’t finish the alignment, then you definitely need to send your 475 Field Communicator in for repair by a specialist.

However, if the procedure works, then you can postpone the maintenance. Still, you know white spots on your display aren’t normal. So you should send your 475 Field Communicator in for repair as soon as you can.

On the bright side, the Emerson 475 HART Communicator has large buttons to work with. So you can do all the functions with them, using the display only as a monitor. And if one of your favorite buttons breaks, then you can switch the touchscreen until you get a chance to send it in.
