Yesterday our TV was making flickering in the picture got up this morning and the picture was black but had sound. We disconnected the satelite and no change. Took it to another hookup downstairs still the satelite but a different box and the tv works. We put another TV on the same hookup where it didn't work and the tv works.

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.
If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.
Sounds like it may be the backlight inverter.
Have you disconnected from the mains when you turned it off?
leave it for 24 hrs then re-connect.
this should be covered if you have a warranty
It worked fine yesterday. Sound on all channels. Sometimes the picture goes black on channel 6. We can get it back by going up one channel, then back to 6.
it is due to cable signal ie weak.
now there is no sound
this is due to sound section
1 loose connect in sound section
2 speaker
3 problem in sound section some part must have failed.
