What LCDTV are you using?  Does it have a SCART input?

I myself use a Dell 780P (a Sony Trinitron in disguise), but some Mac
monitors that conform to true VGA specs can be connected to the IIgs
via an RGB->VGA converter.  I've tried it.  They work as would any
other VGA monitor.  But many older DB15 Mac monitors are really not
VGA at all.. being fixed frequency, or even if multisync, just not
behaving at all with a both a VGA adapter + converter.

There's two ways I can think of... the one Mitchell describes, plus
also one in hardware.  The IIgs has a color killer circuit normally
controlled by its big video chip within the composite chroma chain..
you can trigger it manually if you wire up a switch.   I don't
recommend doing this unless you have and can understand the schematic.
