Hi there, I'm new to this site, and looking for some help. I recently got a Samsung 5.1 suround system and tried to put optical cable from my Samsung to my service providers box. They wouldn't stay in, and after doing some reading, I learned that they have a plastic cover on them. I pulled the optic cable out to find no plastic covers, so I think they are stuck in both units. How can I get them out without damaging either unit? Thanks in advance.
