again on lcd line problem

to cut a long story short: my lcd is ok, sometimes a couple of line but fade away immediately after few seconds that is on...but

sometimes when i hit a pad or put some more force on pressing pad it appears a line and according to the "hits" i press on pads it goes out and in... is this meaning a bad solder or failure contact or is just a normal "ending" of my lcd?
