I have a Zenith SY1324S-01 TV mfd. in May 1997. The vertical deflection is intermittent. Sometimes the picture is fine, and sometimes there is just a horizontal line. Before I open the case, I'd like to know whether anyone: A. is familiar with this model and knows what the most likely cause would be for this problem on this specific model, B. has a schematic, C. knows how to open the case (which is usually the hardest part of the job).
To reply directly to me, replace all 'z' with 'a' in email address.
