Yeno SC-3000 RGB and Controller problems
Post Posted: Thu Dec 21, 2017 7:02 pm
Hi guys,

I just recently got a YENO SC-3000H. I made an RGB cable like on the screenshots below. But I get a predominantly green and red image. I don't know how to fix this because the cable I made measures out fine. I didn't use resistors like in the schematic. But was told that might not be necessary. and the other sceen doesn't really show resistors in it's schematic. Thanks in advance for your help guys!

Ok false alarm. A trace was broken on the motherboard. Now I need to fine-tune it because everything is to green.

It is solved now. A trace was also broken on the motherboard connecting to the pin on the controller port

Can anybody help me with the resistors I need to buy in the first post? I guess they are 220 ohm. But what does the 75 stand for?

The resistors are 75 Ohm

The capacitors are 220 uF (negative leg to scart pin)

The resistors can be installed in any direction.
