Screen has green and reddish spots in two upper corners

We had two large speakers next to the TV, but we moved them about six months ago and occassionally still have spots on the screen.

    I have same model. I had the green problem when I first got it but moving the speakers seemed to do the trick (magnetic interferance?). My tv is also almost 2 yrs old and the last 6 months has begun to turn red for periods of time. sometimes turning on and off the tv will help but it's a real irritant. Tonight the entire screen turned black on three sides and pulled in from the sides. after 40 min it went back to normal. Sanyo won't stand by fixing whatever is wrong. I've had tv's that have lasted 20 years that didn't give me a lick of trouble. Any ideas?

It sounds like the screen has become magnetized by the magnets in the speakers.

Inside all analog TVs is a device called a degaussing coil. When you turn on the TV for the first time (cold), the degaussing coil is energized for a couple seconds to demagnetize the screen and then it goes off.

You can purchase an external degaussing coil and demagnetize the screen youself. A degaussing coil looks like a small hula-hoop about 6-8 inches in diameter with a AC line cord attached. I've even made these coils out of long lengths of enameled wire, electrical tape and a line cord.

Once itas plugged into the wall outlet, you hold it close to the screen (1/2' away) with the hoop facing the screen and move the hoop in a circular pattern, covering all areas of the screen and slowly move the hoop away from the screen while still moving in a circular patten until your about 2-3 feet from the screen.

If you did it right, the color splotches will be gone.

It's possible that the coil in your set is bad. The coil is energized for a few seconds when you turn on your TV and then it shuts off a few seconds later. You can try turning on the set for around 30 seconds, and then turn it off. Wait about 10 minutes and turn on the set again. Doing this several times may let the sets internal coil (if its working) to demagnetize the screen. If not, you'll need to use a degaussing coil.

Let me know if I can be of further assistance to you.

Good Luck!

Sharchet,

Thanks for the solution. I'll give it a try. Also, I have surround sound and don't need the speakers in the set. Would it work to remove/disable those speakers (i.e. will that get rid of the problem permanently?)? Second is it practical to do so?

Thanks again for offering me some hope.

John

Light green and pink spots on my hd tv!!!


Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.

Color distortion


Move any speakers or electrical devices away from the set. It could also be anything electronic or magnetic. Anything near the set that generates a magnetic or electromagnetic field could be causing the distortion.

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

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.

i have found when samsangs convergence are out of range perfect focus will fail. if the are out of range a technician will try to adjust the set in service mode. store these values and then this will be the base for the perfect focus. If the set has a bad convergence cuircit then they have to be replaced.
