Magnavox CDC 745


My Mag CDC 745 has started not reading burned or commercial cds. Also skipping and stopping too soon.If it's a problem with the laser/transport are there NOS ones I can get. Is there compatibility with other players. I really like this player and don't have the $$$ for a new one. Thanks for any help.

The  CDC 7345 has a very mediocre Philips DAC chip (SAA7341) while the CDB 650 and 630 models mentioned above have different versions of the legendary Philips TDA1541 and TDA1541A chips respectively. I would definitely try to get one of those as there is little in that price range ($100-150) that could possibly come close. The transports on these made in Belgium Magnavox players are pretty bullet proof as well.
Two questions-#1-are the Magnavox CDC 745 and the Philips CDC 745 changers exactly the same?    #2 Can the preferred Philips DAC chips be installed in my CDC 745 changer? Thanks in advance.
