[QUOTE="chscag, post: 818137, member: 46727"] Usually if the power inverter has completely failed, the screen will be dark. The power inverter provides low level AC from DC in order to power up the backlight which needs AC power to operate. Your backlight could be failing. Another possibility is a video defect but it's unlikely from the description you gave. Regards. [/QUOTE]
