The bulb burned out on a touch lamp I got at Wal Mart a while back and

What's the likely cause of this and is it something that's readily
repairable?

Thanks.



This is common, the bulb arcs internally when it blows and pops the
triac in the dimmer module. If it's not potted in solid epoxy it's easy
to fix and I've done several. You can get a triac at Radio Shack that
will work, it doesn't have to be an exact replacement. In the dimmers
I've fixed so far that was the only problem.
