Electronics Repair Questions? Ask an Electronics Technician
Hi and welcome to JustAnswer,Thank you for the question and your patience (just came online/regional time difference). Should you still need assistance for information purposes only...Initially, the left hinge with P/N SBHB4E is no longer readily available. The only possibility is to source a Technics SL-J110R being sold as-is/for parts and if this part is still functional with the to-be purchased SL-J110R. Something like the offering HERE.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
Good luck with the Technics.
