Ticking Sound ? Halo

[nxym]

Hello
I am new and i just receive my Halo C2 and when i power up after some minutes start make a ticking sound repeatdetly (same sound as when i press the mute button) This sound stop after i close the back button. I found some threads here about that problem that inform to refit/reseating(?) switching power supply connector or change power harmness ... something ;like that. Where is these harmness? i dont know and i take some pictures from my Halo. Can someone make a red circle of that cable that i must look for?
Thanks a lot.[IMG]xxx[/IMG]

The power supply board is located to the LEFT of the unit (behind the power button). Check the wires to this board.

Thank you all.
I just upload some pics to check if is the correct cable. I mark it on a circle. Is this tha cable that you said before? I connect again all the wires to ensure that it is seating well. Therefore how that only a cable do so faulty noise? I think that it is the same sound like muting. (a relay).

Hey, good job taking that picture with that much detail. For ease of use, here's your picture embedded in your full size:

Nxym, the red circle identifies the correct board. However, the circle is on the high voltage mains input connector (power supply source), and it's not likely to cause any problem. If that connector has bad contact, your unit would be completely dead or totally flakey (like randomly die/restart).

The likely culprit are the multi pin connectors for the low voltage outputs on that same board. Due to the angle of the photo, I can't tell for sure, but if I recall correctly, the two connectors behind the aluminum heat sink are on the power supply (one with all black wires, and one with black/red/orange wires). All the connectors leading from the power supply board need to be checked/reseated at BOTH ends - don't just check the power supply end, check the other end too.

The connector in the circle is the only power supply connector that you don't need to check. It's apparently good since the unit powers up fine :T

Thanks again .My pics is from my iphone. I reaseat all the connections and i am waiting if this happen again. The connectors which pass through to front panel (buttons, volume etc) is difficult to reach and i left it for now.

This thread has gone quiet so I assume you've solved the problem? If not another thing to check is the wiring harness in the very bottom right corner of the above pic (the one with the 4 different colored wires). 2 of these wires (from memory to the balanced board??) route very close to a transistor, and the heat from the transistor can melt the insulation causing them to short intermittently resulting in a clicking sound. The repair is to splice the damaged wires and re-route them away from the transistor. It's an easy repair, should take less than 30 minutes if this is the cause of the problem.
