SOURCE: Samsung LN-S4692D - Vertical lines (>15) & static on screen

this sounds like a scan board gone ,, if you check ebay youll see two things,
1, other tvs for sale with the same fault (It might give you a clue to the fault ie , which board )
2, the same tv as yours with a broken screen ,

i dont know how good you are with taking things to bits but i personally would buy the tv with the broken screen and start swapping over the internal boards ?

Have you checked your home insurance policy for broken tv,s
it may have fell of its stand when you were'nt looking?

Blue and pink squiggly lines in my samsung tv


Very easy and cheap to fix. Go to Home Depot in the building section they sell magnets to pick up nails that fall off roofs,it cost about thirty dollars. Simply pass it over screen(it's OK to touch screen) very slowly. The great thing about this suggestion is that if it doesn't work, take it back for full refund. I sweep my scren about once a month. I have personally replaces my lamp as well as color wheel.

You have a bad LCD control board,It overheats and causes colored lines,screen to darken,or the color go floresent. Also check the power supply for bad caps.
when you have it apart.They usualy go bad on these tv's. It will cause the tv to take longer to come on.Or you have to hit the power button several times to get it on.

Green Pixel or dots issue on Samsung LN-4051D


That's a flaw in the driver/timing circuits, but it could also be something simple like a ruptured ribbon cable or poor connection during manufacturing. Simple or not either way the driver/timing circuits need to be serviced by a professional technician.
