I think that's going to be a mid-90's model. I have a 1995 PanaFlat CT-27F15, which was of the same era except has a flat CRT as opposed to the spherical PanaBlack. 11 years later it's still going well. Except for a dead external audio output after a lightning storm, all else works perfectly. Anyone have a schem they could relay so I can fix it? Internal audio is perfect, just the external jacks are dead. I get a faint output and typical white noise background at full volume, but nothing else. Again, internal speaker output is perfect.

Thanks!
