aminga 500 green screen please help

Does the A500 have a memory/clock board installed in the underside?  If so, open the trap door and remove it.  I've gotten several non-booting A500s to come up immediately.  The battery typically goes in the board and it's gone for good.

Good luck!

With the exception of the trapdoor clock/memory there is no battery on the A500.  Did a previous board leak inside the machine?

edit: Just had a hunch, is the leak from an exploded cap. on the motherboard.  That will take the system down but is easily replaced if you can solder.

Hayashi,

Get it out as soon as possible.  Since the A500+ never really sold over here, I've not had one.  But it should operate just fine without it, you just have to manually set the time.

Get it out and clean the area if it's spilled.  I've pulled several, including my A4000 and 3000, by gently rocking the battery back and forth until the legs break.
