LG 5K sudden death

[jamesfletchernyc]

Hi folks, I have an iMac with 2 LG 5Ks. They've worked perfectly for few months. Today they both won't power up / be recognised - 1 stopped then the other stopped an hour later. My MBP won't see them either. Changed all the cables round. Did a PRAM reset. They're def getting power. Cables are fine. Any thoughts would be so appreciated.

Turns out the power strip was to blame even though it was powering other equipment with no problem.
