@imacpowpcintm it should be the SS board which sets the brightness of the picture on your panel. A failed SS board usually has a picture that is so dark that you only see speckles/blobs of dots that move around. this could be what you described here "very dim dots of red green and blue and they are just a few" Those blobs etc. are actually the brightest part of the picture on the panel and that is why they look the way you do. If you still have your TV apart, lets see the SS board and wires and lets's see if we can determine what is going on with it.
