Behringer DCX2496 fault - easy fix

Behringer processor fault and fix: DCX2496

I am posting this just in case it can help someone searching this forum in future. This info may already be in some other part of this forum, in which case my post just reinforces the statistics of the fix.

My DCX2496 suddenly developed a fault - when turned on, it would show a blank screen and faintly flicker leds on Input A and output 1.

What I did:
1) I first tried a factory reset (power-on while holding both Page buttons down). Had no effect.
2) Heating and cooling cycles had no effect (surprised me)
3) I then opened the lid, and pulled and pushed at the connectors of three ribbon cables. None of the connectors "felt" loose.

I toggled all ribbons but only managed to lift one connector off its female socket, and then replace it.
I closed up, switched on, and for some reason it functioned again. Had to re-enter my config data.

I have since found at least a couple of forums on the internet where a poster related a similar experience, although in some cases nothing brought it back. One user re-started his by connecting it to a PC with an RS232 connector via a USB to RS232 converter. Can't imagine why that fixed it, but there you are.

So if you get the same symptom on a DCX2496, you have something to try. Wild guess - the connectors may not be the highest quality and therefore a pin may have made marginal contact with its seat, which was restored by just handling it.

Despite saying that, when originally launched the product represented quite a powerful and versatile piece of digital processing at a very low list price, so maybe Behringer had to cut corners.

Post "repair", my DCX went through a few long duration sessions and is working ok so far.
