Question about Audio Players & Recorders
Hi the problem is the capacitors in the power supply area it is hard to pin point whiich one it is if you are good with asoldering iron change the lot if the deck has a standby mode and left on in the standby mode this could be the cause if not just age and usage how old is the deck. regards kirk

I had exactly the same problem with my Denon DCD-910. Fixing it is easy, but it took me a while to find out;
In the power supply +10V and -10V unstabilized lines (in front of the 7805 and 7905 +5V and -5V regulators on the heatsink),
there are 2 ICP-N15 devices (IC protectors: very fast acting electronic fuses 0.6A). PCB component print is IC502 and IC503 if I remenber well. They tend to deteriorate over time and break, or a current peak could have made them tripping.
The +10V/-10V (+13/-13V really) is used for driving the loading/spindle/sliding motors and focus/tracking coils ONLY. +/-5V was still OK, that's why you can still see the display.
They have a TO92 transistor housing, but only 2 leads. ICP-N15 are hard to find; You could also use ICP-F15, but these have a different housing.
You could order the original ICP-N15 at utsource.net
An alternative could be to mount 2 polyswitches (also called multifuse), a PTC type current limiting and recoverable circuit breaker, like Bourns MF-R065, rated 0.65 A
I replaced them with 2 radial 800mA PCB solder mount fuses (1$/pc), and everything works fine again. Yet another piece of excellent equipment not to be thrown away ;-)
You have to unmount the PCB from the CD player housing (about 8 screws and disconnect all 10 connectors) to be able to replace the fuses.
While it is disassembled, check for broken solderings, especially on high power devices ( like voltage regulators mounted on heatsink or power transistors)
I hope it works for you too.
