Problem is with a Tascam CD-RW700 standalone pro-audio recorder. Turn on the power and the unit gets stuck at the Welcome! message on the LCD screen and you cannot even open the CD tray.

Remove the rack ears and carefully open the unit, locate the power board (right hand side when facing the unit).

The top part of the board handles audio I/O and the bottom part is the power supply to the various boards (the connectors are a good place where to check voltages).

In my case I noticed one of the capacitor (C07 – the black one) had leaked. I also decided to replace the CapXon cap (C02) since it showed a borderline ESR value.

Specs:
C02….4,700 μF(35V)
C07…10,000 μF(16V)

I replaced them with Nichicon branded caps.

Close, start and enjoy!

Note that I did check the two resistors (R72 and R73) and they were good (desolder one lead to measure the resistance). They should be 470 Ω (1/2 W).
