Question about Televison & Video
I have a Samsung Plasma 58" TV "pn58b560t5fxza" that got a small bottom black curved line while we were moving to new house. The line gets increasing when we turns on the TV. We can stills see the picture on the top portion of the screen but the bottom dark black portion getting increased when we keep the TV turned on. everything else works fine like the sound, buttons etc. I will really appreciate it If anyone can tell me what it is and how much it would cost to fix? Someone told me replace the main board and it should be fine. I want to take your guys advise before proceeding any further. Thanks for reading and your advise in advance!
Hi Mazy, sorry to hear about this...
Problem with plasma screens is that they do have a limited life, they also do not like to travel. You have to keep them upright because the glass panel is so heavy. Did you lie it flat for transportation? Is the black area in the middle bottom or in the corner? If it is in the corner, and the mounting point has a problem, it could cause this, but hard to say without seeing it. Does the black area retreat when it is off and cools down? I doubt if it is the system board, sadly if it is the display panel, it would not be worth fixing.
Let me know if you have more details... Good luck.

SOURCE: Haier Plasma TV problem
My experience with a Haier Plasma 42EP24S is that they have weak software chip that goes bad and can cause a number of symptoms from picture with no sound, will not recognize video inputs, or my current problem tv turns on and off irratically. This is the second time i have replace this chip, which is the socketed chip on the vga/component/dvi input circuit card. Last time i had this problem i ended up fixing it myself because sears took over 3 weeks and still could not figure out the problem. I am working on obtaining this chip, probally get about a dozen so if anyone thinks this may fix there problem as well i my have some for sale. email@example.com of Malobicky Digital Systems.

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

not sure what you're referring to as a "main board", but heres the LCD Control Board for the TV

A plasma screen uses thousands of tiny fluorescent bulbs in different colours (red blue and green) to produce a picture. Just like standard house hold fluro lamps, these tiny bulbs use starters to turn them on and off. As there are so many bulbs in the panel and therefore starters, the panel has a number of "starter controllers". These controllers can control anywhere from a quarter up to half of the screen. If a controller dies, it takes out it's segment of the screen. Unfortunately, it sounds as if this is what has happened in the case of your LG - this is also common in NEC and Fujitsu panels. Althought these controllers can be fixed, it usually takes more time and money than it's worth- unless you have it under warranty in which case the manufacturer will just replace it. Sorry top be the bearer of bad news. hope it helps
