Sony kv-g21m RGB mod help

[neohanter]

Hello everyone
with some of trying to mod my sony kv-g21m1 to accept RGB input unfortunately I didn't succeed yet the screen just goes to black when I turn RGB on with ok sound on composite mode ok but rgb mode showing black screen the chassis bg- 1s and jangle chip is TDA8375A I done everything that should be I take the the RGB lines with blanking line and ground from CN106 and taken 5v from voltage regulator from the board and make divider using two 75ohm resistors for dropping 5v to 2.5v for blinking and use on the scart with between each RGB line and ground 75 ohm also trying with 150ohm with each RGB line and nothing happen just goes to black screen . any instructions to secssed I will be appreciate.

Have you measured the voltage that is making it to the blanking pin?

[neohanter]

Yes I checked the pin 26 on the jangle chip when RGB on and give me 2.2v it's same voltage that's comes out from dvider

[MarkOZLAD]

Can you measure resistance from each of the RGB inputs to ground?

[neohanter]

It's 0.0 ohm smd resistor each RGB line to ground except blinking line it's 41 ohm also with each RGB line 0.1 25v cap

You have your RGB lines tied directly to ground and wonder why you have no image?

[neohanter]

Yes no image just black screen when RGB eneble any solution ?

What part of this picture has RGB lines tied directly to ground?

That’s what I was thinking. You need to remove the 0 ohm SMD resistors.

[neohanter]

the modification was successful just remove the three resistor thanks guys for help and wish you all the best

Did we just throw you a fish or do you understand what you did wrong initially?

It’s been a while but if you have pictires of your mod
I have the same model i wouldve been very helpful
