3 weeks ago, the TV quit working after pushing the manual switch on/off. 2 weeks ago, one TV was staying on 30 minutes and then cutting off. You could turn it back on but it would cut off in 1-2 minutes. Then 4 days ago, 4 more TV's suddenly won't come on. only one TV left working. Now last night that TV quit working several hours after it was turned on and won't come back on. We replaced one of these with a new one 2 weeks ago(under warranty), a wall mounted 42"HDTV flat panel. It is one of the 4 that all quit at the same time and it was the first one that quit 3 weeks ago. 4 of these TV's are 6-7 years old but we have never had any trouble before now. They are not flat panel. The other 2 are new 2-3 months ago and are both 42"HDTV flat panel. What could be the problem?
Hey PNorris,
If multiple electronic devices are failing in your home all at once, I would probably first have to ask if your home recently experienced an electrical storm or major power surge of any kind.
Normally the effects of such large-scale surges are immediately noticeable - TV's and other major electronic devices may fail to turn on, fuses may be blown or circuit breakers tripped, and in some cases electrical wiring may be melted.
If nothing like this has happened recently, low-level power surges may still be a potential cause of this problem. When the motor from any large appliance (such as an air conditioner or refrigerator) turns on or off, it often diverts power to and from other electronic devices using the same circuits. This fluctuation in electrical current may result in low-level power surges to every connected device. While not immediately noticeable, these low-level surges can often cause the eventual failure of (and gradually degrading quality in) many audio/video components.
Typically, the easiest way to avoid situations like this is to make sure that outlets are not overloaded and surge protectors are used with every major electrical device in your home. For older homes however, replacing the house's wiring may be necessary. Homes that were originally built at the turn of the 20th century may not always have wiring capable of supporting the electrical needs of many modern appliances.
Ultimately, this means that in addition to contacting your local TV repair facility, you may want to also speak with an electrician. This is probably the best way to determine whether or not power surges have caused these failures, and may give you a better idea how to proceed.
Hope this helps you out.
Sincerely,
Aaron

Thanks for your help. We suspected lightning, but did not know if this could cause the intermittent outages. Since yesterday, 4 of the TV's have come back on. We think that we may need to get the electrician to check it out. The house is only 6 years old, but one room was just added on, the one where the first TV went out and was replaced 2 weeks ago, but the new one is now out. The cable guy came today and says there is no problem there, but cannot explain what it might be. He says we need a new TV for the one that was playing 30 minutes and quitting, that the cable hook-up is loose and can't be fixed. Does this bring to mind anything else?
