No power HDMI 8" IPS LCD

Hey there, I recently purchased the HDMI 8" IPS LCD, and all was working fine, running off a powered usb hub, for an arcade project I’m working on. Then all of a sudden, no power seems to be getting to the screen at all, no ‘no input’ screen or anything.

I think it went blank when I was getting all the parts put together, as I wanted to make sure it worked before hand, as some of it is a very tight fit.

Any suggestions? I know it may well be pretty wide open. I just have no idea why it’s gone. Is it fried? Is that possible?

Thanks!

I just have the same problem. I would like to know how to test it. How to diagnose if it is the screen that damaged or the controller?
