Question about Samsung LN46D550K1FXZA - LN46D550 46 1080p LCD TV - 16:9 -
TonyI have Samsung TV, model LN46D550K1F. I have voice but no picture. I have a Comcast system. When I turn the power on the blue light on the HD box goes on but there is sound but no picture. When there is a picture the Samsung icon appears on the screen. Is the lack of a picture due to a problem with the TV or is the problem related to the Comcast internet? Thank you,

You should always have all expensive electronics on a surge protector. It sounds like for this set the power regulators blown out as I know this set very well and seen it a hundred times!! its a power regulator IC that cant handle a power surge at all. and if thats your only problem, it shouldnt cost more then 175.00 to 250.00 to repair. Now with a surge though there could be other problems as well but from what you stated Im guessing alls ok except what i stated. Now Please do not attempt to repair yoursels, as these sets have alot of Hi voltage inside them even when they are unplugged.. Good Luck

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

Well the capacitor problem usually causes power up problems. If your tv comes on now it sounds like you dont have the same problem.Vertical lines are usually caused by bad flat panel or dirty ribbon cable contacts on flat panel connections.
