thanks for replying my post!

i did as you says. but i couldn't find the fuse door. there's a
little square plastic cover door in the back with a screw besides it.
i unscrew it and couldn't take the cover off. it probably tightened
to
the body of the stereo.

i tried to take the whole thing apart but i don't have all the screw
drivers, there's some screws need extra long shafted screwdrivers to
take it off.

i had the problem occured after a thunderstorm, fuse burnt-out seems
like a most-probable cause.

this unit is also battery-powered. do you think it'll work if i
install the battery? i'll try it anyway, man, 8 D-sized batteries,
what a monster

Xiongnu,

Do try installing the batteries and see if it works on all functions
(radio, tape, CD). If you can borrow enough batteries from flashlights

etc, this would be an excellent diagnostic test. If it works OK on
batteries, the damage is limited to the power supply and should be
repairable (maybe just fuse). If not, the lightning surge propagated
further and caused additional damage, which could be
difficult/expensive
to repair.

I've never seen a fuse door on these units. Every one I've seen, the
AC line fuse is inside, near the cord socket or power transformer.

The power supply on portable radios, stereos, etc. is connected
directly
to the AC line, and is on whenever the cord is plugged in. This way
the
power switch only needs to have a single set of contacts, to switch the

DC power (from power supply or batteries) to the rest of the unit.
This also makes these devices susceptible to lightning damage even
when
turned "off".
