DNA75 stuck on temperature setting screen

[morpheusneo]

I have a couple HCigar VT75 that I had put away and haven't been using for a while. I got them out and was going to use one but it is stuck in the temperature setting screen. Normally when you select a temperature or "off" and hit the fire button, it will go back to the main screen where you can select your wattage, etc. Mine does not. It stays on the screen where you set the temperature for temp control even if you try to select off. I connected it to EScribe and restored defaults and it did not work, still stuck on the screen setting the temp. Any ideas on getting it working again? Thanks!
