My Samsung LCD TV has intermittent color problems

\015 My Samsung le32b450c4w 32" LCD television has recently developed some intermittent display issues. Initially we noticed a green bias to the picture, then we lost the display entirely, but the sound and back-light is still fine.\012\012Now we have a picture, but sometimes we see the color flicker from normal(ish) back to a green hue, we've also got three light-colored patches at points around the edge of the screen.\012\012So I've already done some digging, there are three boards in the TV, what looks like a power supply / backlight controller board, a main-board, and a smaller "T-Con Board", I've tried unplugging and reconnecting the ribbon cable between the main-board and TCon board, no luck.\012\012Any idea whether this is (a) the TCon board (cheap to replace, yay!), (b) the main board, or (c) something else?\012\012Many thanks all,\012\012Russ\015

I have a Samsung HLP 4674w DLP. The picture started to lose color and look like a negative image. Then it would get scrambled and eventually go out. Powering on and off sometimes fixed it, but only temporarily. Sometimes it would also turn off and on by itself. I thought it may be the lamp so I replaced it, but it did not fix the problem. Next I thought it may be the color wheel so I replaced that, but the problem did not go away. Also when this happens the Power switch will not turn the TV off.

You need to change the lamp out, it builds up a internal resistance, and pulls your voltaged down, it will get to the point where you TV will not come on at all. Replace your lamp, you can get one at ... Samsung HLP4674W 46" Rear Projection HDTV

Hi. I have an LG 47LB9DF-UA LCD TV with a video problem. Originally, I had problem with horizontal lines, accompanied with a lag.
