Noticed the blue was missing from my Race Drivin even after a recap job.
Read many forum related post's and tried the swap of RGB wires to see what happens.
Thought I had it figured out, but apparantly I'm not understanding how the color drives work (new at monitor repair).
Here's the deal:
Also see pic of current/original state.
Went into screen diags to get a color pattern and the Blue only has a straight line as in the pic.
Resoldered all joints on neck bd with no change.
Swapped the Green and Blue wires from the RGB connector on the game board output and the Green and Blue test patten swapped places with Blue still showing a line.
Figured it must be the color driver on the game board, so having a spare, I swapped the boards but no change. I know this board is good.
Sooo... Did I just determine that my CRT and game board are fine, but there remains a problem on the neck board or?
So confused.....
