Power Macintosh 7300 won't start up

[Draefend]

I've just gotten a Power Macintosh 7300 but I can't get it to start up. When I press the start button the LED blinks once then nothing happens. Does anyone know what the problem is?

Don't know for sure if a good battery is necessary, but is a good start.

Try to remove RAM and Cards and clean contacts on the LB.

I have a 7600 myself, not the best of the range...

The Delta power supplies seem to lack in reliability in this day and age... that being said, I have both a 7300 and a WGS 7350 with logic bosrd issues (likely failed caps), that cause wierd behaviour and a failure to boot to  raster, so this is also a distinct possibility.
