Right. I have a note on the diagram that R1455 (560R) can go O/C. This supplies 23v to pins 3,11 and 18 of the RGB module. Might be worth checking this voltage is present. The resistor is just to the left of the LOPT where R1456 (100R, fusible) and R1583 (2R2, fusiuble) live. These are in the same area and might cause problems.
If we're on the wrong track then we'll have a look at the blanking circuit centered around T1535.
