Hello. I have had my Pentair intelliflo VS pump just over 2 years now. I just noticed that the LCD screen is blank. it does not show anything. the pump works fine however. I cannot program anything since i can't see what it is i am programming. i check out to replace the screen i need to replace the entire drive kit which costs $600.00. is there any way to fix just the screen or maybe use some external device to program it? thanks
