If they’re a good reputable shop, they would put a warranty that covers in defects in parts and/or workmanship, at least that’s the case in my shop. Bring it back to them and ask what they can do. I perform and record a functionality test before I attempt any repairs on any device along with sending the results to my customer via email. I do this for a couple of reasons. 1 is to ensure that I and the customer are aware of any other potential issues that way they can’t blame me for damaging something when it was an existing issue. 2 is to make sure everything works before I do the repairs. That way, in case I damage something, I know that it’s most likely my fault and that I need to fix it.
