Default Zx81

Hi everyone, I wonder if anyone has any advice about a TV tuning issue with a ZX81? I have a CRT TV and I can tune it into the ZX81 no problem, but..the picture quality is such that the image wobbles slightly so that the words (I've written a short BASIC program to check to see if the machine works) look like they are intalics - if that makes sense. The TV has picked up the ZX81 signal but it's not 100% correct and I've tried fine tuning too. Could it be a problem with the signal output from the ZX81?
