IMB thinkpad screen fuzzy (updated)

[Leonardo Miranda Collantes]

A few days ago while i was using my IBM Thinkpad T41 and i noticed that there were several fuzzy horizontal lines appearing on my screen, those fuzzy lines became more frequent and it made it difficult to read text and one disturbing thing is that these lines on my LCD only appear when the AC is connected, with the AC not running and only the battery, there seems to be no problem.

Does anyone know what could be the source of the fuzzy horizontal lines?

A old monitor is probably failing (if only they lasted unlimited like ram). I would recommend trying to update drivers if you can.
