DM 7020 YUV-Fix! - 07/09/16 09:42 PM
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.
