Today my client returned me malfunction RB750G

Ether ports are not working.
Attached cable and LED of eth port is not become green. All 5 of them same symptoms.
Caps seems to be fine. They are flat.
what part could I replace to bring it back alive.

The money are not problem and I have plenty of RB's but I really love RB750G.
Is there some chance to be repaired?

First step: hard reset.
