My widescreen all of a sudden developed a blue curved horizontal line through it and that is all we could see and now it will not power up. It looks like it is about to power up as the green light is on for 4 seconds and then it shuts down. Please could someone shed some light on how to fix or proceed if you have encountered similar problems. It is a Mitsubishi WS-55511 widescreen that I purchased in 2003.
thanks for any suggestions
