Question about Samsung LN46A650 46 in. LCD HDTV
Sounds like there may be some bad electrolytic capacitors on the power supply module. This has been a common problem on for this model. There are 2 caps that are 1000uf / 10 volts that commonly go bad on this set. All caps on power supply module that are domed or mushroomed on top rather than flat will need to be changed. Eventially it will get to where it will not come on at all if not fixed soon. If you have any experience working w/ electronics, this a very simple and inexpensive repair to make.yourself. If you take it to a shop, you'll probably pay anywhere from $100-$200 to get it fixed, if it is indeed bad capacitors. If you need any more info just let me know. I've repaired many lcd's w/ this problem before. I would definately start by checking the caps. If you do it yourself, make sure you put them in correctly. You have to make sure the positive/negative pins are in the right position as it's printed on the board.
