I have a Jandy One Touch remote that hasn't been working properly. The display is blank except for a couple lines horizontally through it (sometimes blank with no lines). I've recently found that if its unplugged for awhile or turned off then turned on (when the pool repair guy is there) it turns on just fine so they think nothing is wrong and test it and works perfect! But it doesn't stay like that, maybe 10-15 minutes or until the pool guy leaves and its a blank screen again lol!! The orange power light comes on when its on. It still seems to control it by the programming Ive had in it even though its blank.
