Bright narrow line from right side of screen on PRoView 2200W monitor?

Donald Jones, if it is a single colored lines, it is most likely a TAB error. the binding on your LCD that holds the wiring in place for that particular row of pixels is no longer working. Not the greatest of all descriptions, but in essence that is what happens. You could try and see if by applying pressure on that area TAB on top of the LCD, the line disappears. Ultimately I believe that you will need a new LCD for a permanent fix. Hope this helps,good luck.
