I have the nano vna h and brand new out of the box it has white screen. Now I assumed I was seeing the back light and the screen was toast. No response from "the888store" on ebay where I bought it. But I was using it with the computer and the coax cable I had to solder to it in true hacker fashion. Because they didn't send me any cables at all either. But I had it plugged in to the computer and when I unplugged it.... The screen stared working perfect. Upon plugging it back in when it died...the screen stopped working. I need to know what it is that's causing it to be in and out like this. Anyone has any info I would greatly appreciate it
