There are a few possibilities here. Looking at the back with cover removed, on the left side there are 2 long Buffer boards. The top one controls the top 1/2 screen and is likely bad. It can also be the large Y SUS board the the right of these. The Buffers connect to this board. Go to Encompass Parts or Shop Jimmy's and type in your model #. Jimmy's is FAR cheaper. You may go on EBAY once your get the part # from the other places. John

I have an LG flat screen tv that only show the top half of the picture. The bottom half is blacked out. What is the problem.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

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.

Hi: We had this problem under warranty, and tech installed the following to solve it: Parts BN96-02033A, BN96-02034A and BN96-02216A. This solved the problem for 2 years. I now have the upper half going black now and then for 2 to 3 seconds. I am ordering these parts from www.partstore.com and will just plug them in. Better than a new tv.

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

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
