Scart to Y-U-V Converter on the Fritz

I recently purchase a new 46" Sony Bravia LCD TV. I hooked up my Model 1 Genny via Scart to Y-U-V Converter with set of Component cables. Everything was running smooth, until I tried Street Fighter II - Special Championship edition. The screen go black for second, then returns, repeat. Usually this only occurs at the title screen, but sometimes it does happen during game play. Other games that this happens with are Virtua Racing; Sonic 1 & 2; Golden Axe. Strange thing is, other games will boot up and play the whole time with no problem.

I purchased new Component cables, and the screen still goes black with those games previously mentioned. I will be returning those cables tomorrow.

I purchased my Scart cable from the Sinclair Shop, and its hand made quality is outstanding.

This leads me to believe that my Scart to Y-U-V Converter is on the Fritz.

Its not very old, and I've never dropped it.

Anyone else have a problem like this with there converter?

Any suggestions of what I can do to handle this problem?
