From: Lee Haymond on 10 Dec 2006 00:09 I own a Zenith model SS1913W (Made in 1990) with a slight problem: The horizontal width is too wide - cuts off lots of picture. No marked pots to set it. I don't work on TVs, but it seemed it was somthing to do with the flyback Xformer. How would one set it?

And probably as it left the factory.;-( If no pot there could be a jumper or even an inductor. But be prepared for the geometry to go out even if you can set the width correctly. -- *No sentence fragments * Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.
