Hi there. I have a problem that NO-ONE has been able to assist. It is a very technical problem. Here goes: I get white, broken, horizonal, flashing lines at the top of the tv screen. It only happens in the HD format, [720p or 1080i].--Also it comes and goes! It's very wierd. For example, it will do it during a commercial, and then when another commercial comes on, it will go away. -- What is wrong with my beautiful HD television??-- Thomas K.
Sounds like insufficient vertical sweep and the top lines are getting out of control.
Check all the electrolytic caps in the vertical circuit for testing dry
(sorry - takes a special meter to do it in circuit) or just replace
them. Look the I.C. up in the free NTE crossreference at
nteinc.com get a diagram of its pinout to find what pins the power and
outputs are on.
Hope ya fix it!

My Panasonic plasma does the same thing. There is a line at the top of the picture. It happens on almost every HD channel. It seems like I need a vertical adjustment, but there isn't one on my television. How do I fix this??? It's very frustrating.
I had a 42" wetinghouse and now have a 47" Vizio, both had the same problem. Im not sure it fixes it if you adjust the verticle, it just hides it. I can do that and it will show up in PiP. wierd. My brother had the problem and the line started growing! And it completely ate his screen after awhile. Will and can this happen and wouldnt it be easier and cheaper to just take it back than checking electrolytic caps?Who the hell knows what that is besides you? And the nteinc.com website wants me to join, no thanks and I dont understand it anyway. :/
