    Remove and reseat memory modules? Possibly defective memory module?

     

    You may also want to check the voltage of the logic board battery. For some Macintosh models a bad battery can lead to a no-video condition (but I do not know whether it could explain any error tones).

    I haven't used a 68K Mac in a lonnngg time.

     

    From my expierences, if you got just the Chimes of Death (as I had seen in that YouTube) without a Sad Mac icon  its likely something serious. IIRC, if you get the Chime of Death with grey or black screen, something is stopping the Mac from doing its power on self test (POST.) The Sad Mac icon (along with the chimes) would appear if something didn't past one (or more) of POST checklists.

     

    With that being said, Jan might be on to something. I suspect something along on the logic board. It might be safe to say the logic board is toast, might want to replace it.

    As stevena1 indicated, it may be something with the logic board itself. One possibility could be to examine the board with a magnifying glass and look for cracked solder joints or discoloured/damaged components (such as leaking electrolytic capacitors). One could perhaps also try to temporarily disconnect the hard drive or the floppy drive to see whether that changes anything.

    First thing I would do is pop it open and check to see if the battery inside is leaking, if it has leaked out onto the board it's more than likely dead, at least dead beyond what most people would bother putting into it (unless you like soldering wires to jumper broken traces).

     

    If the battery hasn't leaked I would reseat the ram, or even remove the ram all together to see if it gives the same chimes.

     

    If it chimes without ram, unplugging the ribbon cables from the motherboard and trying again will be a next step. If that fails then try replacing the battery.

     

    The reason I say replace the battery last is I've never seen a system that death chimes with a dead battery, they'll usually play the startup chime but never display anything.
