How do we get the picture back full screen when it will not show the menu because it is only showing the lower half of the screen for some reason


HELLO.
Sounds like one of the buffer boards has gone.
BEFORE YOU TAKE MY ADVICE PLEASE BE AWARE VERY HIGH VOLTAGE INSIDE, IN SOME SETS 2,000 VOLTS DC.
you will need to turn set off for 2 hours before any work is carried out.
as you look at the back on the bottom are 2 or 3 sets of long thin boards, one of them is gone.
either change one at a time or the whole lot.
hope this helps.

Electronic tech needs help this tv only half of picture is showing what could be the problem i wants to fix it myself


Hello Danyell,
According to the model number you provided you have a 42" Insignia plasma TV. The problem you reported with having just a blank black screen on the lower half is due to a bad lower buffer board or also called a lower scan board. The part number is LJ92-01739C and if you Google this part number you can find these online and also find some sites that may show a short video on how to replace it. Price of this board looks to be about $35. Also of note is you will find that this part number is a Samsung part number which means your Insignia TV has a Samsung plasma panel in it so the associated circuit boards will also be Samsung parts.

Sounds like a back-light fault. Check its back-light inverter. To get more details, http://electronicshelponline.blogspot.com/Pull up older posts.

Half screen is blank 42lg20 or 42lg50 when


This is likely to be the T-con board. If the entire screen glows but you have no picture on the second half of the screen then it is the main board, not the backlight inverter. If the screen is half picture and half gray it is the T-con board.


Replacement of one of the above will fix the issue.


Please rate if this helped :)

Half the screen will go blank


it seems to be happening at certain resolutions such as are used
during post screen, splash and those programs.

a lot of kid educational software changes the video output
resolution to run

your monitor would be suspect.

go through the monitor setup, the setup on itself
that doesn't use the computer, see if it has
a reset, see if it has diagnostics to test it out.

42" LCD tv shows picture on only half of the screen,other half dark!


The T-Con board (otherwise known as LVDS) connects to two seperste parts of the LCD panel. If you do have half a picture (left or right) replacing the T-Con board should resolve this issue. Open your TV, find the part number and search on eBay or at sites like www.flattvparts.co.uk where you can search by TV model number.

Picture problem, half screen blank


On a plasma there are 2 buffer boards, upper and lower, it all depends which half of the screen is on as to which buffer to replace, the buffer boards are located usually on the left hand side if you have the back off the unit. You maybe able to reseat the ribbon cables and get the video back up

Half screen activated only


When only a half screen is produced, it is usually a upper or lower buffer board, if the top half is blank then it is the upper buffer, and of course if it's the bottom half then it's the bottom buffer board
