yeah that does sound good, I will dig into it a bit...

It will allow the backlight to turn off.

hmm.. i think you are confusing brightness with panel power. We have always been able to bring down the brightness. Thats the only reason in the past the screen went blank to begin with. Turning off the panel power is a completely different thing. Ive done it and can help you mod the code so you can help me in the long-run patch it up. Since im at work i cant do it right now but i can guide you on what to add from the board-htcrhodpanel.c .

Yes... Maybe.

Yeah sure I can play around with it a bit.

Compare the topaz panel and the rhod panel code. You will see topaz panel actually has more gpio to shut down the panel. We are currently only triggering 0x63 . We actually need to trigger 0x63 and 0x62 in that order according to the dll to shut down the panel. So you can add that for the blank function or if you decide to move it to the client power thats fine as well. to power the panel back up need to do the same but in the reverse order. 0x62 then 0x63. Alsi maybe a 25 msleep in betneen them helps. If you do this, you will notice your panel go pitch black..

This did the trick... But I never got it to come back on.
What have you gotten so far for the code?
