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.

My Philips plasma only shows half the screen. The other half is just blacked out.


This model has PiP (Picture In Picture), find the button on the remote or check manual, this mode is most likely turned on and is being shared with one of the AV channels, or try turning on a plugged in SCART device to see if this picture shows on the other half of screen.

VIZIO P42 plasma, half screen ok, other half showing blank


First you have to check if voltage and data are ok at the Y sustain board and the Y driver boards are not running hot. Even if you know how to replace these panels you must have a scope to adjust the v-set up and v- down. Not just a simple PNP. Trouble shooting a plasma is not a short time process to do it correctly. Please let a service center look at it for you.

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..

Problem with plasma tv


Something in the path to drive the other half of the screen has failed or is broken. Need some basic troubleshooting information in order to be any more specific, but I've seen this problem before with NEC plasmas. If still under warranty better use it Good luck
