Hello This is an indication that your vertical output stage is beginning to malfunction. It could be the vertical output IC or the vertical coupling capacitor. I would suggest using the schematic and an oscilloscope to determine if the signal is correct. You may have to replace the IC or the capacitor.

I hope this helps,

Thank you,

Insignia 32" 720p Flat-Panel LCD HDTV - High-Gloss Black Picture is too big for screen ,cut off all around, top, bottom and sides. Can't read things on screen, heads cut off etc. I've gone through...


try checking the menu setting on your Dish Network, there may be a television format in that menu set up, if it is only when a dvd player is playing, then check the format on that, so on so forth... that is one place to start, check if it is local (TV) or if it is from attached component ( Dish dvr/ dvd etc). also refer to your owner's manual.. if all else fails, call customer service @ insignia

Trying to change tv format on my dynex 32 LCD


You are looking for a picture size, format or screen size button on the remote control to solve the issue. If it connected to a HD cable or satellite box then they also have format or picture size settings.

Picture format to large


There should be a format button on your remote to change between widescreen & fullscreen as well as the zooms. May say format or aspect. If not on remote look through your menus. Make sure which ever u select u do not choose a zoom. This will cut of top & bottom of picture

Picture is cut off at top and bottom


I had the same problem with my westinghouse 47 inch HDTV. It turned out that someone had inadvertently hit the "format" key on my satellite (Direct TV) TV remote controller. If you have satellite TV you might want to check this out. I set it back to the previous setting and I get the entire screen. Hope this helps someone.

HDTV's come with selections that will change the screens display, on the remote press the format button and you should be able to find a setting that you desire.
