Why won't my MacBook power on (the I sight light just blinks)?

I've not been able to power on my macbook for a while now, the powersuply light on the cable is dim (I know my battery is dead) I've tried an smc reset, changing batteries and power cables, as well as starting from an external drive, but to no luck. The Isight light just blinks steadily (it's quite dim) and then blinks faster when I hold down the power button.

Any Ideas (both for what the blinking isight mean and to get it powering on)?

Thanks a lot!

It's a late 2006 macbook (2GHz Intel Core 2 Duo, originally 1GB ram now 2.5GB).

[no liquid damage & the DC-in is fine]

I wondered if it might be the RAM, so tried what you said but to no avail, I then put the hard drive into another mac (same model) to double check that works and get another back, but that all worked fine, as I was doing this (can't remember which hard drive or RAM was installed) my Macbook decided to try and start up on it's own, after sorting that out and putting everything back where it goes my Macbook starts first time no trouble (no rhyme or reason), I had a similar problem a year back took it to the genius bar and after initially saying it was the logic board they told me it was a software problem, so to be safe I uninstalled itaf (an alarm app) as it's the only thing I think it could be as it has a start up damen, so it's now working ok, but is running on 512MB of RAM so is super slow, so I'm gonna check the RAM again at some point to see if it's the 2GB stick or the 2nd slot.

Assuming you're talking about an A1181 white or black MacBook, I would try testing the RAM slots -- power on with one slot empty, and then the other slot empty. Often these machines develop a bad slot, and won't power on when the bad slot is occupied.

Beyond that, you might be looking at some liquid damage. Some people will tell you to replace the DC-in, but really that part hardly ever goes bad. If the memory test above doesn't help, I'd take off the topcase and see if there is any visible corrosion, and if there is, I'd clean it off with a soft toothbrush and 91% alcohol.

I assume you're referring to the sleep light, i.e. the light on the front-right of the machine? I've never heard of the light on the iSight camera blinking.
