Question about Insignia 42" LCD Flat-Panel HDTV

1 Answer

NO PICTURE BUT I HAVE SOUND 42" INSIGNIA/PRIMA

LOOKS LIKE A COMMON PROBLEM. CAN ANYONE BE KIND ENOUGH TO LET ME KNOW WHICH BOARD I SHOULD BE LOOKING FOR TO REPLACE OR REPAIR. I CAN REPLACE CAPS IF THATS THE PROBLEM. I KNOW INSIGNIA AND PRIMAS ARE THE SAME BECAUSE I PULLED A FEW FROM A DUMPSTER WITH BROKEN SCREENS AND TOOK THEM APART. JUST MY LUCK ..I CLEANED HOUSE AWHILE BACK AND TOSSED ALL MY SPARE PARTS.

I just repaired the TV.. It's the main power board that's causing the problem.The biggest board in the TV. I took a metre to the old board and it's failing on the VS circuit. I was only getting 14volts when i should of been getting 78 volts or something like that. If you look on aluminum backing of the screen .. top right corner there's a sticker which tells you what the voltages should be for the VS and a few others. It's the 10 pin socket top left corner on the main power board. VS is the first 2 pins. That's the part of the cuit that caused the screen not to light up. I had audio and power but no picture. All the other readings I took were normal on the board that was failing. Only the VS reading failed with the 14 volt reading. I put in another a good used main power board and took a reading from the VS pins and it was normal. I connect the cable to the y board and the TV powered up and is displays fine. If there's someone who does work on low level cuits and finds the actual part that is failing I would like to know. I replaced my board with a known good one and traced it too which part of the cuit failed. I suspect it's just buying time and don't plan on spending another $100.00 on another board after this one. So any help would be great. Thanks for all Craig

42" INSIGNIA/PRIMA We lost the picture and then 20 min later lost the audio. Changed the main power board, got the power light back but still no audio or video. Any ideas?


In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

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.

No picture with sound


Check the fuses on the Y- sustain and Z-sustain modules. which ever is blown, that board is your problem. Y is on the left and Z is on the right. ( looking at it from the back )

Tv picture looks grainy like it was shot on video


well most lcd and plasma tv's above 36" will look grainy on standard definition because they are made for high definition so if you do not receive a high definition signal to your tv then that would most likely be the problem

Sony Tv PFM-42 V1 doesn't show any picture or tv menu


This is a common problem with plasma tvs You did not mention whether you could generate any sound like through your dvd player or something like that. Whether you have audio or not makes a difference on which board may be causing you the problem. Just because it does not have a picture for tv viewing does not mean it won't produce some type of sound through your av1 input. Try it and I'll try to be more specific.
