Is this no picture on the TV or no picture when you plug in a dvd player or other device?

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 42 lg plasma has no picture but sound


Hello nothing_can_& 20204050, My name is Dave, Are you willing or able to remove the back cover from the TV? If so do you know how to use a DMM (digital multimeter) or at least know some one that dose? My reason for all the questions is in order to figure out what PCB board is bad you need to at least test the fuses on all the main PCB boards (Y sus, Z sus and Main power supply). To do this you will need to have a DMM that can test for continuity. Most of the time the bad board in the TV will have a bad fuse on the board. Please feel free to give me a call or message me if you have any questions or if you would like some additional help! Ask for Dave @ 1-503-432-9904 / pleasefixitdave@yahoo.com

Philips 30" Plasma Flat screen


if you are getting sound but no picture that good at least the set is not
going into protection mode. Which can make fault finding more
difficult.
What you should check is that the 12 volt supply from the power supply
to the signal board is present.
other then that check that you have the high voltages present if this is not
the case then you most probably have an issue with the x control board
or scavio as its known.
