If you'd like to repair it by yourself,
First, download a service manual of the DCP50 from this site;
Second, connect your power adapter(suppose it's in working order, make sure voltage/polarity are correctif it's not original), check whether the CPU receives proper voltage VDD, high level at RESET pin, HOLD switch off, door switch on, PLAY signal can wake up the CPU as expected.

Let me know result for every check point. Good luck!
