About six months ago I upgraded to HD (VIP 612) connected via RGBYto Hitachi CRT digital HD TV. When I press the "Guide" button on remote controller the Guide Screen appears and "Flickers" back and forth to left and right so rapidly it can not be read. I can press the Guide button repeatedly and it will stabilize. Very frustrating. Dish sent me a replacement DVR reciever but it still has same problem. Dish says they can't provide anymore assistance and that problem is probably "TV incompatiblity with reciever input signal". All other funtions of the set-up work perfectly. I previously had a reciever (for several years) with no problem. When I first reported the problem the tech said they would try "a software fix". The problem stopped for a couple of weeks but then started again. Then they replaced the reciever to no avail. I've read vabout a lot of softwaren problems with this older 612 model and I'm about ready to push the MAX button with DISH to resolve the problem with a no cost upgrade me to a newer model reciever or lose a 10+ year customer. Can anyone provide any advice that might help fix this problem before I go to war?
