Electrical surges can instantly overload and short out the circuitry of home electronics and anything else plugged into the wall, or they can degrade them over time. In the United States, most homes use electrical power in the form of 120 volts, 60 hertz, single phase, alternating current.

With alternating current, the voltage rises and falls in a predetermined rhythm. Most appliances and electronics used in the United States are designed to be powered by this form of generated electricity.

A spike in voltage can be harmful to appliances and electrical devices in your home. Increasing voltage above an appliance's normal operating voltage can cause an arc of electrical current within the appliance, and the heat generated in the arc can cause damage to the electronic circuit boards and other electrical components.

Smaller, repeated power surges could be the reason your TV or cordless phone mysteriously stops working. These smaller surges can slowly cause damage, so your computer or stereo may continue to function until the integrity of the electronic components finally erode.

Power surges can also originate inside a home when large appliances like air conditioners and refrigerator motors turn on and off. However, unless it specifically says so, don't assume your plug strip offers surge protection.

You can also install special electrical outlets that offer surge protection. Consult an electrician for further advice on how to install a service entrance surge suppression device.

When selecting a point-of-use surge protector, look for one that has some means of letting the user know if it has failed and is no longer protecting the connected equipment, such as an indicator light or audible alarm. Reattach the cable to the port on the back it was removed from earlier.

Select “Factory reset” or “Factory default” from the list of choices presented on a new screen -- the actual name may vary slightly, depending upon the manufacturer of the TV.

You can also install special electrical outlets that offer surge protection. And if the power surge is created by a lightning strike or power fluctuation on the utility lines, the service entrance surge protection device can reduce the power surge to a lower level before it gets to the point-of-use surge protection device.

For instance, if someone were to raise the level of brightness, picture, or sharpness, even an increase of one, I notice. This is quite irritating to me, as I always looked forward to, and admired, the nice picture I had.

Subjective picture issues like you described are things that could be contributed to source material or other problems.... but definitely not power surge related. If it's a plasma I'd say possibly since anything of the slightest nature can affect them, but if it's a CRT or LCD I seriously doubt it.

As another poster said, power surge damage usually results in a totally dead TV. Some newer TVs like my Sony Sega will display a grayish film picture when the TV is in menu mode and the menu keys haven't been pressed for a while.

Surge suppressors don't protect what's plugged in the outlets from each other. Surge suppressors don't protect what's plugged in the outlets from each other.

Stripping the picture, and leaving a kind of imprint? Aether: NO, as it has been indicated in a couple reply posts now... a power surge, local or otherwise is NOT the source of your complaint.

Maybe it's the other folks in the residence that are playing with the picture settings..... everybody is an expert. If you are still having problems it may be time to have a service shop fix it for you.... things do break and components do go bad.... and as has been said, you can not logically blame it on the power company, so they won't be paying the bill to fix it for you.

As it stands, other people will perhaps notice a slight change in the picture if I ask them, but it doesn't phase them. As yet, I've no idea what brought about this decline in picture quality.

When the TV came back on, there was a reddish imprint on the bottom right portion of the screen. When the TV came back on, there was a reddish imprint on the bottom right portion of the screen.

Hi... Betcha a dollar against a donut that the power flickered on for a fraction of a second and off again during the outage. That may have started the degassing process and then was rudely interrupted.

If this is the case, then a couple of on and off cycles with ample cool downtime between will leave it good as new, with no problem. Try unplugging it overnight, and then plug it back on the next day.

Power surge damage usually results in a dead set that will not turn on. The reddish imprint you saw was probably residual magnetic disturbance from the most recent power outage that went away as a result of the automatic degassing circuitry.

AGAIN... one more time.... ..... the problems you are seeing ARE ABSOLUTELY NOT related to power surges. Power surge damage usually results in a dead set that will not turn on.

Probably not a surge, but a brief interruption, close enough to the average non-tech person. I have seen nearby lightning strikes magnetize the shadow mask as well and cause the same problem, again it goes away after a degauss cycle or two.

FYI, the reason I said to unplug it(not just turn it off), is that some TV 's will not do degassing unless the TV has been unplugged for a long time, plus there maybe some settings in its memory that were corrupted by a brief power outage that might have caused it to misbehave. You could change most peoples screen font to 'clear' instead of standard, and they wouldn't notice.

If this tube is in decline, as I suspect it is, it'll eventually be returned as I do have a warranty. March 19, 2014, was a quiet, ordinary day on Vickie's street in Michigan Center, Mich. Then suddenly the lights began to flicker.

The problem was traced to a power surge that caused damage to appliances in Vickie's house, as well as appliances in the homes a few of her neighbors. Vickie filed a claim with Consumers Energy, assuming it was responsible for the problem and should pay for her damage.

He told us a tree fell on power lines, causing an outage that produced a power surge before the lights went out. “We do not discuss damage claims activity on an individual’s account due to customer privacy issues, but in general terms damage claims are typically denied unless there was negligence on the part of Consumers Energy,” Dadoes said.

Standard homeowners' insurance policies typically do not cover damage to appliances from a power surge, though such coverage is available as an option. Renters insurance policies usually don't provide this kind of coverage, meaning tenants must get compensation from their landlord.

A good point-of-use surge protector many consumers used to power their PCs and other electronic equipment are inexpensive, usually costing between $10 and $20. He covers real estate, gas prices and the economy and has reported extensively on negative-option sales.
