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 there
I would go to menu on the remote , from there to picture go down the list, if you do not find anything there to help you. Go to Support and to the E manual .

Hi my name is Roety,
I can help you with your issue ,
This is most likely a power supply issue
I usually replace the swollen capacitors I can see
A repairman would charge about $300 to replace them for you.
If I have helped you with your issue
If you have more questions you can still respond
I will reply asap
Thanks
Kolbrun
