While checking a IT6000 i accidently damage the main board and one of the other boards which i cannot identify. The number on the mainboard is PWA 137074-13. Some how the number on the smaller board is also PWA 137074-13. Am i looking at the wrong numbers and if I am where do i find the correct number. If possible can some one send me a diagram or service manual so I can order the correct boards from crown.
