There are so many reasons for this fault. You should start with measuring the output voltages from its main power regulator board itself. Actually, this is a skilled work. Any user, who doesn't have sufficient knowledge in electronics, and have experience, can't do this, especially to Plasma displays. If you are sound in electronics, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

Hello
It is due to the power regulator section of your TV. If DC voltage come to T'con board and other circuit board won't have enogh regulated and smoothed current this type of fault will occur. Open your Tv and check for any bulged capacitors on the mains power regulator board. If there, repalce it with same type and capacity. I hereby attaches a picture, of an other set's power supply board with bulged capacitors to give you an idea about how a damaged and bulged capacitor will look like. Check this, If you want anymore assistance from me, feel free to get me by Fixya.

gopakumarg43_41.jpg Note the top of the red arrow marked capacitors. They are damaged. A ggod one will look like one you can see on the top right with flat top surface.

I have a Samsung-HLS5087w that has a dark strip on the right side of the screen. It was about 2 inches wide and now it's about 4 inches wide. I believe this is called a light tunnel problem. What can I do...


Samsung was fixing this problem free up until sometime last year. I am not sure if they still are. If I remember right you have to ask for the executive team. Not sure if they name is correct, but the front line support employees would not authorize the repair, the escalated team would.

If you do a search online, there was at least one forum with alot of people describing their experience and giving better advice on how to get it fixed.
