If you bought it on eBay, you need to open a refund complaint with eBay support and send this unit back to get a refund.
It sounds like you were sent a faulty unit - ebay is very good at keeping its vendors honest.
Aside from that, if you see the activity LED flashing (not the charge LED) when the display is white, it's most likely a display issue.
If you're VERY careful, you can pop the LCD out of its frame and touch up the solder on its ribbon cable.

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
