SOURCE: I have a samsung lcd

Symptom shows it is problem of lcd panel (screen) however, in few cases, T-Con board replacement solved this problem.
Replace T-Con board in an attempt to fix the issue and if that does not help then lcd panel is defective that will cost you approx new tv price.
Following image-1 shows T-Con board location and Image-2 shows how to replace it. These images are taken from related service manual to provide you helpful info.
Required T-Con board is available in for $60 Please make sure that replacement T-Con board is exactly same as old T-Con board.
Hope these info will help you.
Let me know if you have additional question.

My Samsung LN32D450 has sound no pix. it's only 1.5 years old

it could be a backlight problem. Try this, dim the lights in the room, turn the set on. Take a bright flashlight and shine it on the screen. If you see a faint image on the panel, you have a backlight fault.

Tryning to get a manual for my tv mod. ln46d630

The User manual is available in several places. Crutchfield has a link to the manual here: (alternately access it from the Crutchfield product sale page). Samsung also has the manuals but you need to add several extra characters that indicate where the TV was sold. See (the link is a javascript link to a Terms of Use page) for the US version.

I hope this helps.
