Hi, The problem with the image errors in YUV mode is due to a too low capacity of the capacitors at the encoder input of R / C, B, G of the AUDIO / VIDEO SWITCH MATRIX chips (STV6412A). (Test image 6, which is available under "Settings> System> Image and sound> Test".) To Fix: The STV6412A sitting in front of the Scart output. At the pins 10, 12, 14 (RCIN_ENC, GIN_ENC, BIN_ENC) capacitors C3202, C3302 and C3402 are sitting with each 47nF. Each capacitor is a 1uF 16V should be soldered on it parallel. On the direction of the capacitors must be respected. http://www.dreambox.info/showthread.php?158087-DM-7020-YUV-Fix!
