I get audio breakup or loss of picture from my HD set-top box when using an HDMI connection, why does this happen?
Loss of audio or video signal from the HDMI connection to set-top boxes and other video devices has been shown to be a common issue in industry-wide reports. This problem seems to be related to the weight of typical HDMI cables relative to the fragile pin composition used in the connection ports. The weight of the cable may create significant enough stress on the connection port to cause the cable to become loose in the fitting or even become entirely dislodged. Recognizing this issue, the industry is now working on improved connections to be deployed in future devices.
