SAA-2N V2_2 Blank White Screen

How do you know what is a good one?   I bought mine on Amazon and seems ok.  It came with a case connectors, and a test circuit board.

My own issue is that the touch screen is inoperative although the joggle switches work.

Phil,

Mine just did the same thing.  I was using it to measure a new unun, then the screen turned white.

I had not used it in a couple months.  A full charge did not help.

This is very strange that two did the exact same thing.  Almost like a software 'dead date'.

ps - I guess I will try and reflash the firmware

I turned on my VNA for the first time in about 4 months to do some testing. I was using it for about 1 minute to measure the S11 of a 600MHz antenna on a static controlled bench when the screen when black. Thinking the battery was low, I connected a 5v USB charger for a few hours until the LED gas gauge said full. Now, when I turn it on, all I get is a white screen with no image. What's up with that?

Edit: I connected it to via_qt and it seems to be working fine so maybe the display is dead?
