Another console is working off the same sensor and is working fine. It's just that one console that after it receives signal it loses it after about 20 secs then I reset it and it does same thing. I've never seen one have signal for short time then lose it until you reset it. Like I said after every reset signal last 20 secs and that's it
If that's the case, then you can assume the problem is in the display and not the sensor.
What you might try is flipping the A-B-C switch in the console back and forth several times, or even try the other two channels. I've seen the switch in the console go bad and you'd have to set it to "B" even thought the proper channel would be "C". AcuRite told me it might be due to oxidation on the switch contacts. Eventually it got so bad that flipping the switch wouldn't work anymore and I had to replace the display.
