I've just had two bulbs in two separate touch lamps fail. I've
replaced the bulbs and checked the fuses but neither will work.

I took the bottom off one of the lamps and discovered two plastic boxes
about an inch square with various wires going into them, but both were
sealed with hot glue and didn't seem as if they were going to open
easily (and I'm not sure what I'd find if I got in there).

Is there any way to get them working again or are they destined for the
B&Q returns desk? (They're six months old, I've got the receipt and I
think they should last a bit longer than that.)

Also, when they were working and plugged into the upstairs power
circuit, these lights would sometimes turn themselves on when the
bathroom light was switched off. The bathroom light is on the upstairs
lighting circuit. We have a fuse box that dates from the 1960's with
rewirable fuse carriers but the house has been rewired since then and
is in good order as far as I know. Anyone know why a change on one
circuit should cause the touch lamps to switch?

Thanks for any advice.
