The only external input terminals on the main board of the XEL-1, Sony's OLED TV, were the Ethernet connector for the Internet connection, the HDMI connector for DVD players, etc and the USB connector for devices such as digital cameras.
For a TV, the XEL-1 had very few input terminals. We got the impression that Sony had minimized the number of terminals in order to miniaturize the TV.
The connection method of the connectors was interesting. The Ethernet connector was grounded to the upper side as well as to the lower side. The fact probably suggested that a proper ground could not have been established only with the lower side as the connector is generally grounded to only the lower side in most cases.
The Ethernet connector was a surface mount device (SMD) whereas the HDMI and USB connectors were DIP devices (with pins inserted into the printed circuit board). When using an SMD connector, the terminal is usually supported on the upper side because the terminal must be reinforced against mechanical stress during insertion/extraction.
The Ethernet connector used on the XEL-1 was not reinforced from the upper side. We would like to believe that the strength of the Ethernet connector is adequate.
