Long time lurker here..
I bought a Late 07 MacBook in April 2008, with a westinghouse 22 inch LCD to use it in a desktop configuration. The westinghouse has been acting up, artifacts and stuff. Well today it really went wonky.. Everytime I clicked the mouse or held the button down the artifacts stayed and they were really bad. I also noticed when I was plugging in the DVI Cable to the LCD that there was a noticeable spark. Very weird. I tested the 22 inch LCD on a windows box and the artifacts were there but no where near as bad. I hooked up my spare 15 inch Dell LCD I had laying around and it works perfect. Still has a spark when connecting the the dvi cable, it doesnt spark on the pins just the outside metal part of the connector.
Any Ideas guys, or should I just go down to staples and pick up a 24 inch Acer LCD to replace it since they are on sale this week. Typing this on a 15 inch LCD at 1024x768 is painful.
Thanks in advance
