i started seeing the double dash lines on my infinity scren at the end of last summer,I moved it away from all the other plugs I isolated it to its own outlet diffrent breaker still the same results.i thought it might be the probe.i looked everywhere could not find a match for the temp/humidity probe .there were no line on the controller end .I called Ifinity.they said that probe isnt available anymore .I bought it from Amazon ,I looked up purchase date , gave them the order number they had it in their records.immmediatly said theyd have an updated controller and probe .sent to me.so its the controller that is no good not the ballast on the hps lights. so ck your warranty.
