Then why do you mention your Zorro cards (assuming the cards you mention are Zorro cards) ?

Could be the Apollo, have you tried removing it and then powering it up?

Not enough info I'm afraid. I guess your best bet is to remove all the add on boards and see if it works then. After that its general fault finding such as psu voltages etc.
Do you know when it stopped working and what it was doing at the time ?

If the power led goes on then this means that your CPU is running.
But i agree with the others remove everything except the barebone A1200 and try again. The plug in the stuff one at a time and find the point of failure. This also include your harddrives!

If the problem persist, check if the monitor is even working. I have once tried that a shorted monitor cable fried my graphics card (on a PC (but the problem is same for the Amiga)).

Finally check the power supply.

If all this fails, then you *may* have a defective motherboard. Then only three choices persists: change the motherboard (a1200), find someone who can repair it or spend a few weeks not finding the problem (i have done that with an A4000).

Best of luck

 Just a (maybe) silly question: your 1200 lits the HD activity led?

 If so, that's a simple revalidation. Depending on what is the size of the partition not validated, the Amiga will boot in 30 minutes to up two entire days(!).
