KH Director PH Probe won't calibrate

[carmenjeff]

I originally had an internal leak so I opened up a 4 day old unit and fixed the pin hole leak in the tubing. The board got damaged so GHL wanted a 50 dollar inspection fee, since I opened the unit up and I figured they would deny my warranty anyways so that's why I opened up the unit. So instead of sending the unit in I ordered a new replacement board, this time I applied a protective conformal coating to protect the board from future saltwater damage. Everything went well for 1 whole day. The next day the Ph Probe lost calibration and read 0 and ever since then It's just a fancy Paper weight all other functions work even the unit says calibration was successful except it reads 0? Anybody have any Idea what else I can do before I throw this unit in the trash and go back to another solution?
