Get a new CD player...
Yeah, I would look at getting a new one. Panasonic CD players were decent...even owned one myself, but I think other brands are better.
If you want to try to find the exact part, I would call Panasonic.
If you need a new CD player for the low low, I have Sony Refurbished for $65 with full warranty. They also play MP3...my normal price on them are $95 for a MP3 model. 70% of the time, the CD player is brand new and was only repacked.
