Tyson >Greenville SC Unfortunately I saw something _very_ like that on my 17" Nokia 447Xi a couple of months back. Mind you this is purely anecdotal 'cause I don't know what caused it: only what happened. People told me it was probably some interference in the electric line, not the monitor. Later on it got worse and ..I can only describe it as a 'black inkblot' began to appear on the screen for a few moments at a time, said inkblot about the size of a fist. Then one evening real sparks flew out of the area below the screen where the control buttons for the monitor sit, an appropriate fsszzzztt sound was emitted, and monitor was dead. Only the green light would still come on and off if I toggled the monitor's power switch. Fortunately it was still under warranty and I bundled it off to the nearest authorized repair. It was back fairly soon -- about ten days 'round trip -- and has worked without glitch since (about six weeks now; and knock on wood). Clearly _some_ component, or connection, went on the fritz -- and it wasn't the input electric mains -- but what exactly it was I cannot tell you, my not having the know-how to have trouble-shot or repaired it myself. I only tell you because your description of your problem is *exactly* what was happening to my monitor. I hope you're able to resolve it. Would you be so kind as to post the final resolution of your jiggle when you find it? Thanks. jonathan gold [log in to unmask]
