Remote just died one day, didn't drop it or any physical damage. Tried new batteries, I have voltage throughout the circuit board all the way up to the infrared LED. The backlight LEDs and the DBS LED flash shortly once while I connect B+. Most of the Test Points indicate switch activity, but no switch indication returned to the LED under the switch button Eg: TV, VCR... The crystal looks like it is working just fine. The infrared LED checks OK. I have inspected with a microscope as best as I can for a cracked run, but the switch side is covered by a white coating making it impossible for visual inspection. A replacement remote is right at $50, and I'm not sure if a universal will have all the options. They went to the trouble of putting Test Points on the board, so I figured there may be some info/schematics floating around somewhere.
Any help would be greatly appreciated. Bill
