Question about Sharp LC-42D43U 42 in. LCD HDTV
We just bought this TV and I have noticed that when watching
DVDs the brightness will fade in and out. It almost looks like when you dim the
lights. It is not constant, but rather sporadic. It does not seem to be happening unless I am watching a DVD. I am using the same player that I used with my old TV. Any ideas on what could be
It called dynamic back light, every time seen changes from dark to bright and other way brightness of back light lamps changing too. So, it's a feature of the TV, unfortunately, it does not work properly all the time.

Have you tried watching the TV function when just viewing normal TV? Does the problem still occur? I think the you may have a signal problem in the path between the DVD player and the TV, check your cables. Now what might also be the issue is input of the TV try using different inputs, sometimes there are incompatibilities with some of the input ports and equipment used on those ports. This happens often. If all else fails I would get a schematic and start looking at the RF, HDMI, Composite Video, S Video, and component video inputs and start comparing signals with the information from the schematic.
I hope this helps,
