SOURCE: blue snowy pixel areas on my plasma

some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.

SOURCE: I have a samsung 52 inch lcd tv and it takes about

T-con or timing control board is defective or the syscon link board that feeds the panel itself... For that problem you'll need to take it to a shop - the whole Tv has to come apart to get to the T-con so it can be properly tested...
Good Luck!

SOURCE: 42" LCD tv shows picture on only half of the screen,other half dark!

The T-Con board (otherwise known as LVDS) connects to two seperste parts of the LCD panel. If you do have half a picture (left or right) replacing the T-Con board should resolve this issue. Open your TV, find the part number and search on eBay or at sites like where you can search by TV model number.

My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines

Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.

Are you using a cable box or a satellite receiver? They too have format, Zoom, or view mode buttons.. It seems like there's several names for them but they do the same thing. I hope this helps.

Blue Streak

I had the same problem w/ the same TV about 6 months ago. You need a new optical engine. Hopefully you are still under warranty. Once that was replaced, the tv looks great.
