According to an aftermarket lamp
manufacturer, there are 2 different lamps (1st and 2nd
generations) available for the Samsung HL-R4667W, but only one of them
will actually fit. The lamp that is commonly associated with
this model, BP96-00826A, is used in
housing that has a silver bump protruding from the opposite side as the
front face of the bulb itself. The other type, BP96-01073A, is
placed in a housing that has a smooth back face and a overall larger
bulb. I can verify that the HL-R4667W that I own seems to have the
second type of lamp.
As long as you didn't open the housing of the lamp that you purchased to
try to install the lamp in the housing that your TV came with, you
might still be able to request an exchange from samsungparts.com, given
Theres a cover on the back that is vented w/4 screws on like the corners,also theres a symbol that looks like a "T" on it,take that cover off and right behind the symbol "T" an arm like plastic piece is what hits a lever inside when then cover is installed ,flip that little blue lever up and down a couple of times with the set unplugged reinstall cover making sure the "T" is in the position to hit the lever and tighten not too tight.
if this don't work it may be your colorwheel.Good Luck!
Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!
