I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.

SOURCE: samsung lns4051d 40in has horizontal lines across

This sound likes the incoming signal is week. You should play a DVD player to see if the problem stays same or not.
If you try all sources ie HDMI, AV Component, etc...the TV show the same problem. There are two possibilites: T-Con board or main board need replacing. You should need technician to figure out the problem. Hope it help.

Hi have a samsung 42 inch plasma, all of a sudden it has a band 20cm wide of dotted lines going across the whole screen, some channels or when playstation in use the band gets wider, does not seem to...


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.

How does it help to have a Full HD LCD TV?


Hi - welcome to Fixya,

There is no advantage in buying a Full HD (1080p) TV if you are only using it for watching TV. Currently, there are no Full HD television broadcasts and there are no plans to introduce any. All UK HD channels currently broadcast in 720p resolution whether they are on Sky, Freeview, or Freesat. Therefore, any TV that is described as 'HD ready' rather than 'Full HD' will display all HD channels at maximum quality or resolution.

The advantage of Full HD is when using them with Blu-ray DVD players, gaming systems, e.g. Sony Playstation, or for playback of media files from your PC. These systems output at 1080p / Full HD (but only when connected with an HDMi cable) and you would need a full HD TV in order to get the best quality / resolution from these systems. However, you don't need a Full HD TV to connect these devices as they can all display their output on a 720p HD Ready TV.

The main disadvantage of any HDTV (1080 or 720) is when watching standard definition (SD) broadcasts. Full HD TVs have 1080 horizontal display lines, but SD broadcasts only have 540 horizontal lines. When watching SD channels on an HD TV, the other 540 lines, i,e half of the picture, are being created by software within the TV - known as 'Upscaling'. Upscaling requires processing by the TV which takes time and fast motion can seem blurred or blocky/pixellated as a result. Higher end TVs have faster response times (0.5ms or less) which minimises the pixellation so this specification is important when selecting an HD TV for purchase.

Hope this helps.

Regards,
BElectric

I have a 40 inch Samsung TV which I've had about 3 years (sorry I Don't have the model number handy). I have DirectTV and an HD-DVR. The HD Channels were great up until about a few weeks ago. Now sometimes...


If your menus on the TV and other inputs look good then it is probably a resolution setting on your Directv box that needs to be changed. To get HD it needs to be set at 720p or 1080i. Please take a moment to rate my answer. Thanks....
