I just recently starting using a CLCx. After a few days, when I start up the computer the LCD will show the EVGA logo when it first turns on, and will then go blank or have dim bars running across the screen. Changing anything in the software does nothing. But the pump and fan settings still all work.
 
Any recommendations to troubleshoot this?

Looks like it may have been a software conflict? I was messing around with different RGB software, and now that I have uninstalled them all. Seems like the LCD is working again with no issues.

Ill updated this if I figure out what exactly it was

Thanks for the info. I'm curious what caused this. 

It went blank again, so maybe it wasn't. Ill recheck all the connections and see if I can do anything to reproduce it working and going blank.

Try disabling all of your background programs for the troubleshooting. 

Its been working all day with no issues. I haven't done anything different. Guess there were some electrical gremlins in there that had to work there way out.  
 
ETA: Haven't been able to recreate the issue for the last week or so.
