Monitor

1 hour suggests some kind of soldering problem on one of the components inside the monitor. When electronics get warm they swell up a little and that small amount of movement is hurting you. When it cools it contracts and that small amount of movement helps you and it works again....until it gets warm again.

In theory it can be repaired the question is>> Who in your area will do it and do they have a wiring diagram with board view and all the stuff to do the repair with..soldering iron, microscope etc...
 
Thank you Kshipper, it is a good point. I will look for a technical shop and see. Your suggestin gives a hint to look. thank you for your advice.
