MUX modding refferals?

Post by Gonflabbles »

I'm in need of assistance with someone overlooking a draft i have for mux modding a crt i own. Its a JVC TV20F242 TV. Ill include some views of the service manual, but heres the gist of what I want to do

Remove 2.2K to GND resistors on the RGB in lines, add 3X 360 ohm resistors to each leg of the 2.2k ohm resistors that come from the OSD RGB from micon. Here i would lift legs from R684 and R685, and lift a leg of the jumper of W357, because an SMD 2.2k is on the under side of the board for this line. From each of the 3 lifted resistors, i add the 360 ohm leads, as well as the video signals (or RGB wires) to my connectors, where i would terminate to ground with 75 ohm resistors.

My issue, is im not sure if the signal is being fed correctly. It appears the actual voltage regulator resistors are on the RGB out lines of the jungle chip, not the inlines. Please confirm my hypothesis, and guide me towards the right way.
Thanks! :)
