You may want to replace the 120 ohm resistor on the sync output with something a little larger, I raised the sync output to 1.9v to try to stabilise the picture on my TV. SCART normally expects a sync voltage of around 1v peak to peak.
I wasn't able to get a stable picture in all modes using this adaptor but I think it was partly because my TV doesn't really like 60Hz modes, and partly because the signal from my laptop is slightly off-spec. Even on a real IBM 5153 it displays off-centre (IBM CGA is fine).
You're welcome to have the CGA->SCART adaptor shown earlier in the thread for the price of postage btw, don't need it now I have a CGA monitor.
