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.
