Recently, one of my laptops have had its LCD go bad: a lot of flickering, colourful lines will appear (the more wellknown version of this problem is that the LCD displays one or several horizontal, colored lines permanently. That is not the case here: the lines are very animated.) The significance varies greatly: at times, its like an old TV not finding its channel (only in color), while at other times, I am actually able to see what it is going on on the screen, but its frightingely bad: the cursor will leave a trace after itself etc.
This first happened about a week ago. While trying to connect it to the TV by HDMI, it initially did not work. Suddenly, I saw the screen on the TV, but at that time, the original laptop screen was also working perfectly. The screen has been working perfectly for about a week now, but yesterday the problem came back. In particular, the screen is usable (that is, I can see what is on it, but it is very flickerish) during the bootup and the initial loading of Fedora/Win7, after that, it tends to go "old-TV-not-finding-its-channel". As well as the obvious question asked in the title, are there any suggestions to fix the specific LCD-problem, without replacing the screen? (I checked the screen, all cables etc. seem to be where they are supposed to, and none are loose.)
If its noteworthy, changing brightness and all that stuff works perfectly.
