    Same problem. the bottom half of my screen on my 42 samsung plasma has suddenly disappeared. It comes back every now and then, and just as inadvertently, suddenly disappears again. Doesn't matter what channel I'm on.

Well, as per my last posting, I thought I would share. The problem of the bottom half of my 42 inch Samsung Plasma blacked out - meant a trip to the local TV repair shop. I have to say, they were great. I took it in and they were able to fix it after replacing a part - had my TV back in about a week. Cost was approx. $300. This was well worth it, considering how much I had paid for this TV only a few years ago. I had the repair done last month and so far, it's been great. Sorry, but I can't remember the name of the part.

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.

50 inch samsung plasma that is 3 years old occassionally gets a black bar across top half of the screen. is this tv done?


not necessarily, sometimes the connectors that feed the screen get old and dirty

If you have some electronic skills, open the TV and clean the connectors around where you see the symptoms and you may have a good chance to get if fix by doing that...

Screen Problem


I have been trying to fix one of these tvs and found out from a repair man that the lower half going blank means a problem with the lower buffer. and that is also what the manual I downloaded says.
have you checked that?
