To anyone out there with a Pixi who still has this problem:
CRT TVs can be hard to find these days, and on humid summer days its hard to find a cat with enough electrostatic charge to bring your phone's screen back. My Pixi suffers from this problem, and the TV only works for me for 12-24 hours at a time. Plus, it seems that heat and vibration (or dropping the phone) really exacerbate the problem. I think I've found something, though, that seems to help a LOT more than a TV screen.
Whenever the problem occurs, I:
- Remove the Phone's backing
- Remove the battery (even if the phone is on)
- Wait 15+ Seconds
- Replace the battery, along with something else to really hold the battery firmly in one place.*
- Replace the phone's cover and turn the phone back on
*I use a half a post-it note. I fold it a few times, wrap the edge farthest from the battery terminals with it hot-dog bun style, then stick the battery in. When I replace the cover, there's a slight bulge where this paper lies.
Hope this helps. Let me know if it works for you.
EDIT: I also find that keeping the phone *cool* and *vibration free* helps prevent the issue. I.E. I don't keep the phone in my pocket anymore.
