Amiga 2000 won't start

[AmigaWorkbench]

Hi!
I’m having difficulties starting my old Amiga 2000. The screen is all white and the classic Amiga Workbench boot screen (a hand with a floppy disk prompting a disk to be inserted)  doesn’t show up. Further, the green hard disk light under the Power indicator doesn't illuminate.

Other than that (!) the computer starts up (sounding normal) and the monitor’s (Commodore Amiga model 1080) power light is illuminating.

I’m not sure what is wrong really, if it’s the Hard Drive or if I’ve connected the monitor cable properly.

Any ideas as to what might have happened is highly appreciated.

Cheers!

Thanks for you reply, VingtTrois!

Actually, I'm not confident enough to tamper with the hardware. I haven't used my A2000 since circa 1994. I'm not sure which ROM I've got, but I've got a couple of floppy disks named Workbench 1.2/Extras 1.2 if that might help determine which ROM I've got.

Like I mentioned earlier, my A2000 sounds "normal" during start up but if memory serves me, I think there should be a green light under the Power indicator on the far left of the computer. This green indicator doesn't illuminate. Could this indicate a Hard Disk failure?

I'm considering selling my A2000 as I don't have space or time enough to use it, but I just thought it would be a good idea to check the functionality before doing so. I have no idea on the amount of labour or costs that might required to make it work.

I can't find the scart connector (which I assume should be used to produce image). The only cable I found was the TTL.RGB connector with mono video/left audio/right audio inputs...
