Sony SLV-555UC ejects record protected tapes

[Guest]

Hello there. I have a Sony SLV-555UC that will eject record protected tapes but not blank tapes that haven't had the tab broken off. Also, when I play the tapes that have the tab intact the audio is broken up and the picture is black with static lines through it. The front lcd display looks dim, so maybe a power issue?? Any help would be greatly appreciated, thanks!
