No one seems to have an answer

Hi there. My problem is this; at the VERY TOP of the tv screen, there are white-broken horizonal flashing lines[ across the top of the picture ], not across the entire tv screen. Here's what I mean. It only does it in [full screen] HD format,with the black bars on the side. [never wide screen HD format]. MITSUBISHI says the problem in in my directv hd receiver. Wrong!! I replaced the hd receiver with a new one. --SAME DAMN PROBLEM!! So it is oviously the TV. Whats wrong with it. Thankyou,--- Tom K.

Sorry this was my solution I forgot to sign in hope this helps you : If the lines dip down enough this could be true what was said by MARR. Although in your case it seems as though you are talking about the white line you can barley see at the top when the tv is showing hd in 4:3 format. This is caused by the hd signal is underscanned and nothing inside the tv will fix this problem this is a signal issue. The way to get rid of this is with your tv remote you need to change the Aspect to "Just" this will not cut off any picture and will take care of that line. You are free to zoom etc...with your sat remote. Make sure you make the aspect change I talked about on the tv itself this should get you set up. See this all the time now...all models all diffrent type of signals all brands/

White flickering line across top of screen


Set the screen format using your TV's menu. Do not set the format of the screen using your provider's receiver. I had this prob with a few channels with a dish provider when I set the format with the remote from the dish provider. I picked up the TV's remote, went into the menu, set the format, problem fixed.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

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!

Thin horizonal line in middle on dark screen


The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.
