This was a really easy guide thanks. I had ordered a replacement DC in board but found after opening I could have probably repaired the existing one. It had been tripped over a few too many times. I think a bit of re-soldering on the connector where the tape covers in step 17 may have fixed mine. Now I have a backup at least.

Hi,

Does anyone happen to know the values of the L2 and L3 parts on this DC-in board?

I am looking to reuse them but I cannot find any specs.

Thank you and regards,

Vincent
