Why is the picture unstable when connecting an SAT receiver or DVD player via SCART RGBs?
| Some receivers or DVD players transmit too high a video signal level or too high a direct current component via the SCART connector. As a result the internal sync stripper may not correctly separate from the FBAS signal the frequencies needed for synchronisation, and the picture may then be displayed in unstable or distorted fashion. In this event the setting SCART2 should be selected under the menu item Option1/BNC Signal or SET UP. When this is done the synchronous line (the yellow connector = FBAS signal), which had previously been connected to the HSync input, will now be connected to the Video1 input. Connecting a 75-ohm resistor along the HSync line will also help.
The same phenomenon also occurred recently with the SCART D-Sub adapter when it was connected to the RGB1 input. Because no 75-ohm adapter is available on the market for this purpose, we recommend soldering a 75-ohm resistor into the SCART connector between PIN 18 and PIN 20 (FBAS line).
