First off I did a search and I did in fact find a number of posts for different models of BB, where users have reported that their screens have gone black without warning. In each case the device is still powered up and fully charged. While each reported that this effect happened during different applications all reported that with a battery pull the screen reset to normal. The problem is that none of the threads really was informative regarding a cause and a better solution than a battery pull.
I have a Storm 1, unlocked that I bought a while ago on ebay and was originally on a BellSouth? network I think. I am on a work assignment overseas and presently am using it on the TIGO network in Latin America no problems. Recently, while either checking email or responding to email or BBM the screen will go black while I'm typing. The screen does not exhibit this behaviour while scrolling or while talking on the phone. The usual scenario is that I will be typing and without warning, drop to black, not fade to black just boom! black screen. Initially I tried randomn mashing of seemingly appropriate buttons, to no avail. Then I went with the all purpose battery pull and after a full restart usually the screen that I was typing on was saved and I can continue to type and finish the message. While the battery pull/restart works it gets old if you have to do it two or three times in order just to finish a BBM reply.
Again, the battery is fully charged. The device has not been dropped or dunked in the water and though I have felt enough rage to have winged it at a wall, I have thus far resisted, though just barely. This appears to be a known problem.
1) Is there a known cause and
2)Is there a known solution?
Thanks and regards,
