Use a credit card to pry the black, plastic, back cover off of the device.

A little lever is holding the ribbon in place. Lift the lever with your nail or a 2.5mm flat-head screwdriver. Move the ribbon away from the circuit board.

Fold a small piece of paper several times until you have a shim about the size of a penny.

Place the shim on the CPU, which is the top leftmost black box on the motherboard.
While the repair does work, had the author bothered to state how big a piece of paper to start with, how many times to fold it, how thick it should be when one is done folding the paper, why one should remove the mother board when the CPU chip is exposed when the back is taken off & etc. then I probably would have given him the 30 points.

Bought this remote at Goodwill for $15. Repair went flawlessly in 10 minutes. THANKS!!!!!!
Hello Tyler,
If you are going to place the shims on the top of cpu, why you have to remove the motherboard completely with screws and ribbon cable from the remote?
Thanks
Sweet fix thought mine had died
