Yesterday I connected up my IIe to a TV the normal way (yellow Composite cable) its a PAL IIe connecting to a fairly new 20" Flat screen. The Apple has also been connected to 2 other new Flat screens (including a 42" which was quite awesome looking) with no problems on either TV. However on this TV, the image switches from black to the apple screen then back to black again in seconds. I am pretty sure its a problem on the TV side but does anybody have any thoughts on what could be the problem?

Your hunch is right. The TV is having trouble locking onto the signal. Woz took "liberties" with the signal specifications, and not every set can respond appropriately. Some TVs have tighter timing constraints and don't appreciate the out-of-spec signal.

I didn't say that at all. He took some very creative liberties with the video data stream and achieved some very interesting results with an absolute minimum of hardware that the video display devices of the time tolerated completely. Times changed, that's all.

If you have an old vcr or other device that has composite input, you may still be able to get it to work by connecting it through a device that will act as a middle man.

what are the chances of using a Composite to Scart adapater? The TV has a scart input, and I'm pretty sure I have a few old Adapters around.

Thanks for all the help, Unfortunately no go on the adapter trick. Tried the VCR suggestion but using an old DVD player that has composite in and out, but lack of a second composite cable to hand, i used the Scart out to the tv still got the same problem.

Oh Eureka! I found an old cable with red and white composite ends, plugged the red into the yellow video slot on the DVD player for video out and the other red into the yellow video in on the TV, and it's all fine and Dandy! woop no need for another screen!
