I have the same problem with my GY DV 5100 camcorder.
Maybe anyone can help us through the procedure to eliminate pixels on these cameras.
It was done once by my service department on my DV 5000 camera, but I like to do this myself for the DV 5100, if possible. I presume the procedure is the same as for the 5000 (it is almost the same camera) but I didn’t get the procedure for it.
