PowerBook 3400 - chime then death chime on boot

So after battling with 'StrayaPost for the last few days, I finally have in my hands a PowerBook 3400. Its awesome. It'd be even more awesome though if it booted.

When I boot the machine it makes the normal Mac boot chime, and then a couple of seconds later plays the broken glass (death chimes) I initially suspected bad RAM, so I removed the third party RAM. Didn't make a difference. I then stripped the machine down to little more than the bare logic board with the power board connected to the LCD and keyboard. Still nothing.

As such it seems like its a logic board issue. Anyone got any ideas? sad

Mmmh… If you tried without the RAM card, it's maybe a bad on board 16mb RAM .
I suppose you've gone through the usual Zap-PRAM-remove-PRAM-Battery and all that.
Maybe try with another RAM card.
3400c/Kanga can be very troublesome machines … I have 4-6 in different state of non-booting or booting to grey screen with no apparent reason.

Ah yes - should've mentioned, the PRAM battery is long gone, was the second thing i pulled out after the RAM, given that its the original I assume it would certainly be dead. I disposed of it to prevent it from leaking over the machine's innards. A 3400 can still boot with no PRAM battery, correct? I hope the onboard RAM isn't bad sad

Do you see any drip marks on the area below the pram battery spot?  may need a cleaning still. 

Power boards have 2 or 3 caps that caused issues with the ones I messed with.

Now I have a working 3400 I was able to prove the bad caps on it do cause issues with boot.  Only really one cap on motherboard but it seems to be a non issue for me.

Your issue was batteries that ate keyboard ribbon connectors tongue

I can see a bit of white discolouring on the metal that the battery was glued to, but nothing on the logic board, no. And the keyboard ribbon cables appear to be intact.
