Question about Samsung TXN2771HF 27" TV
I have a Samsung 27 inch HD TV. It is about a year and half old. My power temporarily went out during a lightning storm and my TV was on. When I turned it back on it had rainbow colors all over the screen. I have unplugged it for an hour or two and kept it turned off for a day. Neither has helped fix the problem. Is there anything else that I can do?
You need to borrow or rent from a repair shop a degaussing coil. Its a big coil of wire that plugs in and has a switch on it. How you use it? With the coil plugged in,but not switched on ,hold the coil in front center , about two inches fron the picture tube. Now switch on the coil and slowly rotate the coil in a circle all the way around the picture tube and at the same time pulling slowy away fron the front of the picture tube. Keep doing the circular motion till you reach about three feet from the front of the tube, turn the coil sideways fron the tube and quickly shut off the coil. This is done with the tv set on. The set should look clear now ,with no color blotches on the corners or the rest of the picture. If it dosent then the pictre tube is bad. If it does look good, shut off the tv set for a hour or so , turn back on the tv set, Is the colors back on the screen. Yes , then ther thermistor or degaussing circuit needs to be serviced, and this is something you will need to call in a tech to service for you cause theres extremly high voltage inside these sets and not for a handi-person to tinker with. But if its good then your all set. Good Luck
