Fujitsu siemens PI 1536 monitor problem

[kenvello23]

I have a Laptop Fujitsu Siemens Amilo PI1536 since almost 6 months.From about 2 weeks, I have noticed on the bottom side of the screen, from left to right, a whitish bar persisting.This happens only after some time from the turning on of the laptop, at the beginning being no problem. Do you know what may cause this? If I change the visualization angle, the disconfort caused by the white bar adjusts a little bit.

THANKS

please check video card temperature;
see if it is a good contact between cooler and video chip
remove dust from cooler
