No Output and Input LEDs are Maxed Out

Hello! I just purchased an Axe Fx Standard unit that has no output. The unit powers on and the control features and display on the front panel are fully functional. Unfortunately, I am unable to get any output signal whatsoever. Also, the input LEDs are maxed out even when I unplug the input cable. I am wondering whether a firmware update would help. Here's what I have done so far:

  • I checked my guitar cables and external amplifier settings---all good.
  • I checked the input jack and the connector between it and the mother board with an ohm meter----all good
  • I checked the backup battery voltage---all good
-I disconnected\reconnected the four black cables between the control board and mother board--no effect
  • I selected the "RESET System Parameters"- no effect
  • I tried to get a signal from the Out 1, Out 2 Left and Right ports with no success.
  • I noticed that the "Status" Input levels \ Output levels are all maxed out even when the input cable is not connected.
  • The Input and output knobs have no effect of the levels.


Please let me know if there's anything I else I should do and thank you for your advice....I would greatly appreciate it. I would also appreciate a photo of your mother board to see if the previous owner accidentally switched the four black connector cables between the mother board and control board. Thanks again!
 
Update: I found a blown capacitor on the mother board today! Amazon sells replacements. I'm wondering if replacing the capacitor will solve the problem or indicates other problems that caused it to blow. I would appreciate any advice that you guys have on this issue. Thanks!!
