Query: "Iffy" remote function

This component video switch comes with a remote the size of an extra thick credit card. Unfortunately, the remote control function works only intermittently. The switch works fine otherwise. The remote response problem seems to be with the switch itself, since it continues even when I use a universal remote which has "learned" the functions of the 3-Play's remote.
