I have a question about my old Mac "iMac G4".
Is it impossible to use a 20" logic board on a 17" iMac G4?

The logic board on my iMac G4 (17inch) broke and I looked for a logic board. I was only able to find a logic board for 20". I also bought a power supply for 20" at the same time.
I tried to boot up my iMac G4. And it makes a start-up sound, but the screen is white and won't go on. I also tried to boot the DVD, but it won't start. I have also run PRAM clearing but it won't start. I can't even get into single mode. I boot up my iMac G4 and after some time has passed I touch the keyboard and I hear an error sound.

Thank you,
 
Sorry, I wrote in the wrong place. I'll rewrite it where it's appropriate.
