RA plus failing?
Posted: Sun Sep 16, 2018 5:04 am
I have had my RA plus for about 6 years and other than it's occasional idiosyncrasy it's been a great unit... that being said, I think the main unit is dying/dead. It's stuck in BUS lock and throws a ATO timeout on reboot, I unplugged everything and rebooted it but still BUS locked. While that was occurring it simultaneously would read 0 on all temp probes, and my PH would read 3.11-3.61. After a couple days of this my LCD now shows nothing, backlight will come on, but it's just a blank grey screen. I pulled the unit apart and there is some very slight corrosion on the main chips pins. I cleaned it up as best I could and put it back together, but to no avail. Have I missed anything, any ideas?
it still seems to be running everything just fine, I can still turn ports on and off from the app on my phone, but I don't get temp in the app either, just a 3.11 PH. Could the LCD itself have gone bad causing this problem?
I did just order a replacement RA plus head unit board...
