Sounds like your backlight is going out. For example, you can take a look at this link on determining if that is the problem.

It appears that you may be correct. A little update: When the screen goes to sleep and is then awaken it will be dark. Twice I was able to use the cursor to restart. I was able to do that with great difficulty and the light has to be just right. On a restart or manually restarting the screen will come back to it's correct resolution. I have changed the timing to where the screen plays pictures all the time. Doing so and the screen does not go dark.
