Right, but the question was about how to reduce the backlight level. This is a control that many LCD florescent lit TVs have. The control reduces the power going to each florescent tube and reduces the amount of light; it has somewhat the effect of reducing the brightness level, but an added benefit of reducing the electricity that the TV uses and allowing the florescent tubes to last longer.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
