Fab LG Flatron 22EB23PY-B monitor but faulty connection inside.

Over the last year it has occasionally gone off and i've had to remove the power cable ... and reinsert the cable then it works again. so am thinking it has to be an internal loose connection near the power socket. Have tried another cable with no success. It's a fab monitor and will be sad to see it go. will take to recycling if no interest but had to put it out there. No scratches. any marks on screen are dust but dont have the right liquid to clean
