Hi, I have a Samsung LN40A550 LCD TV which I have had for just over a year. ... I was watching TV yesterday and all of a sudden the picture went all. ... started makinga very high pitched buzzing sound with no picuture coming on. We did have a bunch of green vertical lines, but now just a black screen.

Hi my LG 47ln5700 tv set has thin greyish black horizontal lineson one side of the .... I hope this works good with Samsung LCD as well....
Dave you know your stuff man !!! You helped me fix my black line fix on my LCD / Plasma and then now you helped me get rid of my green dots on my screen !! You rock . thanks a Million
I have not noticed that with my set, Sony Bravia 2007 1080I.
Uh, I have a bigger problem though...
I had just paused my live tv for about 40 minutes on abaseball game and now I have green burn in.
I'm in the middle of searching the net for solutions. I have tried:
pure white screen for 30 minutes (no change)
"fuzz" for 1 hour (no change)
turn TV off for 12 hours (no change)
I'll now try to power down fully for 12 hours and see what happens.
This is no solution but a point in a probable direction.
A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.
