both lights are solid on and it is not very warm.

Another possibility -- the omap "on chip" firmware will use SD-based
uboot image if it finds it, instead of flash. If the plug plays by the
same rules, you might be able to put a known-good u-boot on an SD and
use that image.
Marvell chips lack that. TI and Samsung were a tad more thoughtful.

After one year of working, in mine some power supply capacitors blew

ocd, catatonic. we're goign to have to choose one. :-)
thanks for the info. i'll take a look.

no output from uboot at all. no output of any kind.
Assuming it isn't hardware death the only option I can see is re-flashing.
i haven't cracked the case. does anyone know if there's
a jtag port at all in a sheevaplug?
Even if there's no ready-to-use JTAG port on the board on the PCB there

There is. I've used it to debug Linux boots with openocd.
The FTDI chip at the the USB-device connector should show you two serial ports.
Yes there is :-). It is another endpoint in the usb. I would try going at it
with openocd. My jtag driver doesn't do reflashing yet.

no
Is it configured to use a serial console? Tried checking the output there?
What's the output from uBoot, if any? As a last resort, tried re-flashing
it over JTAG?

mine reset yesterday and now no longer responds
to the usb/serial interface and the ethernet lights
are stuck.
