That sounds to me like a hardware display problem in your unit. This is why these things come with a warranty. I think you need to contact PHP and explain what you're seeing (including the banding when plugged into your PC).
I'm guessing they will give you an RMA# and replace your unit. But, don't send it to them without talking to them first! If you DO send your unit in, make sure you set your truck back to stock first.
However, BEFORE you call PHP, with your truck set to stock, connect your unit to the PC and through Pegasus update both the firmware and the calibrations: [Updates]->[Gryphon Update Manager]. And then, reload your custom tunes into the Gryphon using [Updates]->[Custom File Download] or [Updates]->[Targeted Functions], depending on the version of Pegasus you have. It's possible your problem can be cured with a firmware update and it's certainly worth a try.
