2 solutions i found.
1: as a virgin engineer (HA!) said, turn up the backlight. fine, except that messes with the picture quality, and increases energy usage.
2: find a floppy disc, and cut a piece of the internal floppy plastic, to the same size and shape as the receiver on the box, and stick it on with tape or somesuch (regular old clear tape works well) over the receiver. this filter all but the ir light.
had this problem myself, suffice to say most of the virgin engineers are NOT well trained. i once had to explain the difference between a switch and a router...... to a BROADBAND TECHNICIAN! :facepalm:
