Well, I have a stuck pixel and like you no program or technique has removed it. Also, I have a weird issue where by my screen goes black for a few seconds when watching Fringe. I'm going to call HP tomorrow for a new one. Worst case scenario I can return for a full refund within 7 days using the Distance Selling Regulation law and place an order for another from my lady friend
Let me know the outcome, I want to call as well.
