Target Display Mode only works if to can boot into the OS. So no luck on that unless you can get it to boot.
How is the logic board faulty?

Just because you "can't boot" doesn't mean the iMac's logic board is "faulty" -- until you have exhausted OTHER MEANS of booting.
A perfectly good Mac can get into a "no boot" situation if the software (OS) becomes corrupted.
What do you see and hear when you press the power-on button?
Do you see any onscreen display or alert at all?
The easiest way to check this is to try booting from an EXTERNAL drive that has a "known-good" copy of the OS on it.
Does that iMac have a DVD drive?
Were there original install DVD's that shipped with it?
Can you get ahold of a USB flashdrive that has an OS installer on it?
Do you have access to an external drive that has a bootable copy of the OS on it?
I wouldn't write it off until I tried some of the above "alternative boot" scenarios...
