Hubble's main camera, the Advanced Camera for Surveys (ACFS), has shut down following an electrical failure.
The camera went offline last year after a problem with its power supply. That was eventually resolved, but this time most of the the damage looks permanent: NASA says only one of the ACFS's three sub-cameras is likely to be restored.

On Saturday 27 January, Hubble's main camera, the Advanced Camera for Surveys (ACS), stopped working. Until a solution, at least in part, can be found, Hubble will work with its remaining instruments.

I hope it's still under warranty.
...or there won't be anything worth servicing by the time the servicing mission is ready to go. :(
...though the BBC report is more optimistic, saying:
Hubble is due to receive a new camera during a planned servicing mission by space shuttle in 2008.
This should recover all of the capability lost in the latest failure.
"The successful completion of [the shuttle mission] and insertion of Wide Field Camera-3 (WFC3) will take us fully back to not only where we are now, but where we want [the telescope] to be in the future," said David Leckrone, Nasa's senior project scientist on Hubble.
