Re: 42" samsung ed plasma tv
There are several things that can cause it. You are best to
have an expert technician come in and take some test on it in order to
determine if it is from vertical blanking failure or something else. It is not
easy to fix this yourself, if you have no experience, because there are a lot
of parts that have to be removed before you can reach the components. It could
be as simple as a loose connector ribbon or a bust capacitor, but it could also
be more complicated. Hence, in my honest opinion, better get a qualified
Hope that helps!

This video covers how to fix a Panasonic 42" Plasma TV model TH-42PX600U that has vertical distorted ...
if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board. but better to replace both a the same time.
if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.
I have the same problem, currently searching for a solution. Have you resolved your problem yet? Looking to repair myself, any tips or ideas that you have/expirenced would be greatly appreciated. Thanks, Todd
This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.
