Question about Samsung HP-R5072 50 in. Plasma HDTV

Bottom half of the screen is black on Samsung HP-R5072 50 in. HDTV Plasma Television

Dear Sir/Madam,
The Plasma TV started to show the following symptom about 2 weeks after the 1 year warranty expires :-< :-< :-<:
The bottom half of the screen is totally black.
I contacted Samsung support and they asked me to do reset: 
1. Turn off the TV. 2. unplug the power cable. 3. push the power button 3 times. 4. wait 15 minutes. 5. plug back in the cable. 6. Turn on the TV.
That steps worked like a champ the 1st time I did it.  But then after a few days, the symptom comes back, and the reset procedure no longer works.
I again called Samsung support and this time (knowing that reset procedure above doesn't work), they suggested me to get people to fix my TV with charges .....
Do  you know any solution that I can do myself.  I'm an hardware engineer (computer and electrical engineer) so I'm not intimidated to fix the TV if there is instructions ...
Thanks in advance ...
PS: "Tapping" on the side of the TV (left and right) does not seem to help.  Unplugging the component cables does not help either.

Re: Bottom half of the screen is black on Samsung...

I have a solution. My Samsung plasma had the same problem with the bottom half of the screen being black. Follow these directions and it will not cost you a dime, just some time. I took the back panel of the tv. I found the lower buffer board on the left hand side. I disconnect all the ribbon cables. Use an air cleaner to spray out any dust on the ribbon connection and the board. I connect the ribbons back to the board. My plasma is now as good as new. If you have issue with the top portion, do the same with the upper buffer board. I was going to buy a new tv but I'm glad I gave this a shot first. It's been almost a month and it's still working fine. Hope this helps and hope it saves you some money.

Re: Bottom half of the screen is black on Samsung...

I have the same problem. I did not purchase this Samsung myself. My insurance company purchased it to replace a 42" Gateway I had that was stolen. (By the way - loved my Gateway). This is the first and only Samsung TV I will ever have. I'm typically a Sony buyer, so I guess once I can't take this any longer I'll replace it. For now I keep a basket of stuffed toys next to the couch and toss them at the TV and that seems to fix the problem. Good Luck everyone with this POC>

Re: Bottom half of the screen is black on Samsung...

It does sound a lot like a buffer board problem, Just which one is the question. Sometimes it is in fact a connection issue. But 1/2 of the screen missing sounds like maybe connection between the 2 buffer boards. It could possibly be the panel. If that is the case. ITs over for that set. But i would suggest first calling samsung and asking them to extend the warranty for 90 days or so. Sometimes they will do this for nice customer such as yourself. 1-800-SAMSUNG. Let me know how this turns out first then we can proceed further if needed. Good luck and keep me posted. Sincerely Jay

Re: Bottom half of the screen is black on Samsung...

Thanks for the suggestion.... It is actually what I did. It took a while, but I argued with Samsung that since I bought my set in December 2005, and the problem with the connections was acknowledged by them in November 2005, they sold me a TV that they knew had a potential problem. After being rejected and told they would not extend the warrenty, I called back and escalated. They agreed to provide the parts at no cost and I had to pay labor (turned out to be $200) to have them installed. This was done about two weeks ago. I have not decided yet whether to try and pursue a reimbursement for the labor at this point or not. I figured I had better have the repair done before I argued further and they changed their mind on paying for the parts.

Just for information sake, before the repair, I was still having intermittent problems with the bottom half going blank, but just a little gentle tap would restore the picture. I had to decide whether to live with a minor annoying problem, or spend the $200 to get $800 worth of parts installed. I have now probably spent a little less than what an extended warrenty would have cost when I first bought the set.

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.

52" Samsung that the top half of screen goes black.

the HDTV has a heat-related problem check your fans. Do they remove heat? the vertical chips paint the screen from top to middle and, middle to bottom so; your top to middle vertical chip is overheating as is your video chip; that is why you have "glitter" in the back ground. get rid of the heat or, bye,bye TV.
