Blank screen on startup, devo 10, help

I seem to be having two problems right now. One is that when I turn on my devo 10, running the latest nightly, the screen lights up but is blank, white. The radio is working otherwise, that is it binds and controls the plane currently in memory. I'm not sure is the buttons do anything, but all the controls work. This is happening along with the much worse problem I experienced yesterday when the transmitter seemed to power down briefly, causing a crash. I tried to describe that problem in another thread here. Any thoughts on either problem would be greatly appreciated. I love deviation, it is amazingly versatile, and when it works, is the best, cheapest way to get flying. It works really well with some complex programming for the DLG, and I'd hate to have to give it up, but crashes are not okay.

To add a little info, I started the Tx in USB mode and was able to get into the files. Then, when I cycled the power switch, it booted normally and the screen is behaving normally. Still wonder why it happened.

Brightness and contrast settings went wild? You replaced the files with normal settings and everything's back to normal. Maybe you accidentally pressed a button when it was on the page setting brightness and did not notice it.

Or you turned the Tx off/disconnected the thing while the drive was mounted, and managed to corrupt the settings file?

I'm pretty sure I didn't press any buttons or anything like that. i also didn't replace any files. I booted the tx in USB mode, plugged it in to my computer, looked at some files, but didn't change anything. I turned it off, unplugged it, and turned it back on. Now it is working normally. If I corrupted the settings file, I'd expect it to behave the same always, but maybe not. To rule that out, how should I fix it? Thanks for thinking about my issue, BTW.

The 10 has known power supply issues if you've got multiple extra rf modules installed. This usually expresses itself as a missing CYRF module at startup, but maybe it caused something else to go into an odd state for a bit? There are hardware fixes for this in the forums, but I haven't tried one.

No added modules, bone stock Tx.

Whenever I have re-flashed the deviation firmware from a newly downloaded .zip file, my DEVO 10 screen is pretty much blank and unreadable. I have had to go in to the tx.ini file to edit and save the following lines to get the screen to show up where I can read it:

brightness=1
contrast=10

Could that be your problem?

I will check out the settings, but the weird thing is that it fixed itself without me changing anything. I was having this problem, started in USB mode, looked at some files but changed nothing, turned off the tx, turned it back on again, not in any mode, and the screen was back to normal. I might try reinstalling the nightly build and unmounting it properly.
