If your LCD display is turning itself off due to aging capacitors, an easy work around is to turn the brightness down! Brightness goes down, display draws less current, and you can at least use it. As it warms up you should be able to gradually turn the brightness back up but probably not all the way.
Sometimes this problem manifests itself as a display that turns itself off after a few seconds or will turn itself off and back on over and over again.
I hope this is helpful to you!
