My son put a magnet on the screen of his InnoTab2. Now it has a blank spot on the screen where the magnet was. Is there any way to repair this?


LCD displays are not affected by magnetic fields like CRT displays are. It sounds like the display might have been damaged by hitting it with the magnet and if this is the case the display will need to be replaced.

Westinghouse LD-4695 led hdtv bought it less then a month ago and its showing white cloudy spots around edges to pictures of it and they came out blue idk if its because the home theater speakers were all...


Depending on how big your speakers are and how they were to the TV....that might be the reason. Magnets are the worst thing you can have next to electronics. It either that, or you bought a lemon, or you have a kid in the house and they put magnets on the tv for fun.

My tv has black splotches or pools on the bottom


If the splotches are a shawdowy black and look like mold growing between the Lens, its most likely dirt or water spots on the bottom of the large mirror. I cleaned mine and missed a few water spots on the bottom of the large mirror and the splotches (spots) showed on the screen. Other than Dirt, or water spots, There is nothing else that I can think of that would cause this. Unless the Someone has cleaned the screen and it soaked up between the lenes. But it Takes about 30 minutes to disassemnble, give it a good cleaning and put it back together.

Tv rainbow in screen


The picture tube has become magnetized, possibly by someone getting a magnet to close to it. You can de-magnetize it using a strong magnet (cow magnet or similar). Place the magnet as close the the screen as possible without touching it to the screen. Starting at the middle of the screen and slowly (not too slow, about one full circle per second should do) move the magnet in a circular motion. With each full circle move the magent twards the outside (making a larger circle) as well as moving it farther away from the screen. Using a magnet will not harm the screen, so play with it and you'll soon get the feel and will see what you need to do.
Tv's have a circuit built in to 'Degauss' (demagnetize) the screen each time you turn it on, but this will only work if the set is 'Cold'. If the set is left off for 2 hours (to cool doen) and does not demagnetize when you turn it on the circuit is faulty.

My picture was distorted by a speaker magnet


well , yes , you have to purchase a DEGAUSSING COIL to take care of this problem and know how to use it (which its very easy) available at electronic stores (try EBAY) What you do is you place the DEGAUSSING COIL in front of the color spot and do circular motions while slowly stepping away from it . that should take care of that.

A magnet touched my screen


My son touched my television screen with a magnet in two spots leaving two discolored areas on the screen,purple and green in hue. I read many quick solutions to this problem on the net and none seemed to work completely,so what i did is took the same magnet that touched the screen and held it in my fist,then with TV on i waved my fist all around the screen working from the spots outward to the edges and this worked completely! Hope this helps someone..
