Have this trouble with my 150i ELITE LCD. I got in the case, and got the first problem with the triangle. After alot of going back and forth i got it to work and found it in ICUE and everything (Dont have a clue what i did just followed the guides that is out there).
2 days ago, i got LIAN li strimers for my computer. So i disconnected everything and connected the strimers, and put everything back together the lcd display worked but not the strimer so i was going to dissamble everything again so i could get the strimers and do a RMA. But now when i connected everything again it doesn't work. I got a red triangle, and doesnt show up in ICUE.
First time when i had this problem i found the display in the ICUE software but not the commander pro, now its the other way around, i dont find the LCD but i find the commander.
I followed one guide i found on the corsair forum. That said i should download this program "USBDeview" i did. And when i disable the LCD display, and the enables it my picture gets back on the display, but nothing in ICUE.
