Hi
I have a BM5 that does not work.
There is nothing on the screen. The unit  BM5 turn on,disc spinning, fan working, but only 3 of 4 test led's are showing voltage .
+5v-ATX- ok,  +3,3V-ATX - ok,  +12V- Blank -ok, +5V_SB - NOT OK.
Only the red light on the BS5 screen lights up. It does not blink, it's only light.
I tested a screen on another BM5 running and the screen works normally.
I also changed the disc from one BM5 to another and the disk is working normally.

Is the power supply problem or on the motherboard?
Is it possible to repair by replacing the condensers?

Thanks for the advice.

The leds are there to give a status about the PSU. So, in this case the 5SB powerline is dead.

I suspect more than just a capacitor.
