Look for the chip SONY CXA1645M. Follow the diagram. If you can’t find 75 Ohm Resister. You can use 68 Ohm.

S-Video Mod

 

Region mode

I follow a guide from Fwonkas (Here the link)  You will need a 45-Watt Desoldering Iron and slowly remove jumper R22.

Region mode 1 Remove R22

 

On R24. You can do two things. Bridge them together and you won’t need SPDT switch. If you do want SPDT switch. I use a SPST Switch On and Off. I tested and work.

R24

 

This is what I use SPST Switch. When is OFF it on the US mode. When it ON it on Japan mode. Do this own your own risk.
