Why don't try to "restore" the CD? Does it work? Generally it's hard to "fry" components with a soldering iron especially the semiconductors.
Also an advice to all tweakers: Get schematics for the gear, be sure in what your are doing and also the probebilty to succeed. Secure the "restore" if it doesn't work! Don't throw away removed parts. If you want to sell the gear it's important to be able to restore it!!!
One guy in Sweden has tweaked his Sennhesiser Orpheus amp and he can't get it sold because of his tweaking. It's a collectors item and must be in it's original state. The amp costs 120 kSEK!!!! (1 USD = 9.40 SEK)
