    Hi Jestine,

    Yes a block Diagram is easy to understand what's on a LCD TV than Schematics although each have it's differences and usage to a repairer for much understanding of it. Thanks for the block diagram.

    Thanks a lot Jestine, I love starting out with block diagrams on a tough repair. Its like your other post last week. It keeps you out of circuits working already when troubleshooting. Hey in your opinion, do you think all lcd tv's could be considered like monitors in your monitor repair book except for the tuner, if, and sound circuits added when repairing.

    HI Jimmy,

    Yes it is almost the same except that certain LCD TV design may have some extra section/board for additional features.

    If yours is a LCD TV then check the backlight. If one of the backlight have problem the display will shutdown.
