Dear ones,I started a flash process and when it didn't finish for a long time, I shut the device down.Result is no display on the screen when powering up. Loading a new script directory and powering up doesn't start flash process. There's just no display. Sometimes there's a short flash of light from the screen when powering on. And then it turns black.Is there a way to regain consciousness?Where does this device look for a boot sector?Blessings,Shahar
