NOTE about repairs and replacement parts: Assuming that you purchased it less than five years ago, or bought it from the original owner, and then transferred the warranty to you, then you are under warranty - which covers both parts and labor. However, the DC-1 is a complex component, and any DC-1 that requires service or repair MUST be returned here to our plant in Tennessee, where we have the test equipment and expertise necessary to ensure that it will be properly diagnosed and tested, correctly repaired, and returned to original performance specifications. In the past we have occasionally supplied replacement parts for installation by end users. However, because we can’t reliably determine which part is at fault without actually being able to test the unit, and because of the possibility that an incorrectly performed or incomplete repair will result in a unit which performs poorly or unreliably, we have determined that this is not an effective repair strategy. Therefore, from now on, ANY DC-1 EXPERIENCING A HARDWARE MALFUNCTION MUST BE RETURNED TO US HERE IN TENNESSEE FOR REPAIR.NOTE: The ribbon cable is quite tough, so the fact that it was "folded" under the front panel to provide clearance for other parts doesn't suggest that it is damaged. (Unless the ribbon cable is actually torn or broken, or the insulation cut to expose bare metal somewhere, it is almost certainly OK.) They may be able to send you the front panel parts and you can get someone cable to install it for you. I've only seen a DC-1 with an intermittent RCA connection. Where are you located? Is my DC-1 under 5 years warranty? Do I need to pay for the front panel parts? If it is the cable problem, I may buy a AWM 20624 ribbon flex cable 1 mm pitch 25 PIN (Not sure 1 mm pitch?) locally. BTW, I am in Hong Kong. |

To be completely frank, I would say that the cable normally isn't folded completely under the front panel shield like that, and I would rather that it wasn't (mostly because it looks a little odd). However, the cable sort of "finds its own place" when you push the parts together, and the cable itself is very tough, so it's very unlikely that it would be damaged by that. (Our support guys looked at your pictures and agreed with me there.) The fault is more likely with the OLED itself, or with the internal attachments between it and its host PCB, which are not things you can fix yourself.

As a guy who fixes and builds computers; that ribbon folding doesn't look like an issue at all. Many small computers (mac minis etc) have ribbon cables folded tightly all over the place, they're built to handle that.
However, from the images posted above, it looks like the ribbon is no longer 100% connected / sitting snug in the plug? It looks like one end of the cable is snug, the other end looks like it is slipping out. Look closely at the width of "white" and "blue" in that image. The transparent blue plastic shows more white under 1 end than the other.

I have had numerous cable issues of this type particularly in the UMC-1 where odd problems were fixed by reseating them (both ends) - things like loss of 1 channel or low levels sometimes. Not sure its possible to get the other end of the cable...Im at 30,000 feet above Australia on maybe the most expense hour of internet I have used ... US$11.95 / hour. They also block Voice calling apps like Skype/FaceTime etc.
text messages work fine tho.

Tomorrow is a sort of big holiday here (Thanksgiving) so we're closing early today, things may be a little behind, and we won't be in tomorrow. However, we are open Friday, so, if you haven't gotten your RMA number by Friday, PM me here with your actual contact information, and I'll make sure you get one ASAP.

The DC-1 has not sent to Emotiva. I checked the 25 pin flexible cable with a multi-meter and found the top five pins and bottom 1 pin are not connected.  |

It it clearly that the cable is damaged. Hope to get a new cable and switch on the displays.

They may be able to send you the front panel parts and you can get someone cable to install it for you. I've only seen a DC-1 with an intermittent RCA connection.
