You don't have any magnet anywhere near the TV do you ?
If not it sounds like something magnetic is interferring with the picture.

If not get the warranty out :D

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.

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.

Monitor is showing bottob half display and upper half is blackout


Hate to say it, but time for a new monitor... will cost you WAY more to fix than to pop-by a garage sale and grab a new monitor.

(It's not even worth a repair-persons time to do it...)

I have a 42' LG plasma that has now has a 1 1/2 inch verticle stripe on the right side. It used to come and go but now rarely goes away. Any ideas?


I believe that this could be a type of "burn in". If you watch anything with a black stripe on the sides or bottom of the screen often, then this could be the problem. My suggestion is to watch things that have no black side bars for a while (>week) and see if this eliminates the problem.
Good Luck!!

Just a half picture on the screen


1. Remove the rear cover 2. remove the perforated large shield on the main board housing (almost in center). 3. Unplug the right top fan and temp sensor plugs ( two small plugs at the top of the main board). 4. Remove screwsthat secure the main board housing, there is also four screws by the video inputs. Do not unplug the board, just gently pull it away 6 to 8 inches. 5. Remove the cover with the Top fan attached (more screws). 6. Now the scan board for the top half of the screen is exposed. The board has four large heat sinks with two large Electrolytic aluminum caps next to each heat sink. 7. The problem caps are at the very top right side of the scan board C192 Nichicon 220 uf next to the IC, the other cap is C120 100UF on the lower side of the IC next to a heat sink. I replaced them without taking the board out. C192 is the one that failed, the other one tested OK but I replaced both.
I got the caps from Mouser.com they are 69 cents each, the Mouser part number for the 220Uf is: 647-UUD1C221MCL1GS (Nichicon 220uFm 16V 6.3x7.7 mm surface mount); the 100uF is:647-UUD1E101MCL (Nichicon 100uF 25V 6.3x7.7mm), both are 105 degree C. I bought two extra spares in case I need them for the future.
Reassemble the unit in the reverse order and you are done. Note if you test it without closing everything, make sure you have the main board shield back on, otherwise the screen will bleed due to the noise from the board. good luck! mine has been working fine.. just like new..
