My tv shuts off after about amionute

My TV shuts off after about a minute. I have attempted to cheange the battery backup in the event it was the power supply. I also tried atthing an extension cord and used another outlet across the house. It's not the picture tube, since it wroks for a min, and the sound shuts off too. It's aldo not a fuse since it goes on for a min. At least to my knowledge it's not the above issues.... Any ideas?

    My LG RU52SZ30 shuts off randomly too. After between 2 to 15 minutes it just switches off. I can turn it on again but none of the solutions mentioned so far have worked.

Could be a temp issue or bad cooling fan.

My RCA smart tv won’t stay connected to my wireless internet and won’t give me an option to connect to a wireless network. Please help!!

I have a RCA sled 48g45rq and mine shuts off every time I hook to the internet and will shut off every time I turn the TV back on until I disconnect the internet. I know my SSID is broadcasting for sure. I can hook it up wireless or ethernet and it does the same thing freezes and shuts off it's what these TVs are known for. I wish somebody could tell me where the backup battery is to hold the information that's stored in it cuz that's what's going on is that the time doesn't stay correct and just like a computer it shuts down and doesn't work until you correct the time on it. And that's because the battery backup in the computer has gone dead. I believe that the people who built this TV and programmed it forgot about that if you know what I mean. I don't know if there is a fix for this all I know is people keep thinking that it's the internet's fault and no it is the TV

Samsung 55" LED UN55D6003 Intermittently turns off and on...T/S help

DO NOT ATTEMPT ANY REPAIRS, CALL THE FACTORY PHONE NUMBER IN THE OWNERS MANUAL AND FIND OUT WHERE TO HAVE THE TV SERVICED, IF YOU ATTEMPT ANY REPAIRS THEY WILL VOID THE FACTORY WARRANTY. THIS IS CAUSED BY AN ELECTRICAL FAULT INSIDE THE TV, IT SHUTS DOWN AS A SAFETY FEATURE TO AVOID ANY FURTHER DAMAGE.

I have an APC XS 1500 UPS. We recently had a power outage and now the display states "event 9" and the unit beeps every 15 minutes or so.

This "Event 9" means that the UPS has has 9 events. It could be going on battery or a high input or output. Either way we can reset it. You will have to turn on the UPS. Unplug it from the wall and also unplug the battery. When all is unpluged push and hold the power button for a few seconds. This is the reset. once done hookup the batteries and plug in the ups. All should be better. Event 9 will be gone. Till next time..... When it will say "Event 10"

My tv cable box and radio are connected to my cyberpower 485. quite often it shuts off my cable box and tv and beeps, the radio does not shut off. This time when I pressed the siver button it tries to...

It sounds like it's either at the age where the batteries need to be replaced or there is a problem with a component 'Capacitor or transistor' on it.
Is it still under warranty. If not - if you pull the batteries out of it you may be able to find some replacement ones on line. Place the part # of the battery in a search engine.
A Good place to try is CyberPower's website also.

My Powercom UPS battery backup is lasting for 5 minutes than it is shutting down.Can you provide me the solution. Model No. is 2200APRM1320W It is very urgent, please.

The UPS can temporarily provide power to IT hardware in the event of a disruption to the Mains power supply. The UPS should stay powered up for long enough to enable the hardware it is protecting to be powered down in a controlled manner, before shutting off itself. The 5 minute period seems reasonable for such a task (although significantly less than the rated time), and if at any point within that period the Mains power supply comes back online, the hardware could continue to work.

I note that this particular model is supposed to provide battery power for 85 - 95 minutes. The amount of time it can supply regulated voltage for will depend upon the load placed upon it. The greater the load (in terms of current drawing devices), the shorter the amount of time that the UPS will be able to provide power.

There may be a Manufacturer Limited Warranty period (parts): 2 years for this model, although labour charges will probably be made.

Insignia FLAT screen LCD tv

It's more than likely over-heating. You can try a Battery BackUp with AVR (Automatic Voltage Regulation) built-in to see if possibly your electricity isn't coming in as cleanly as it should. If that doesn't do anything different for you then you'll have to take it to either a repair shop or back to Best Buy (if it's still under warranty).

Tv shuts off

This shutting on and off~On Durabrand TV`S. If your Tv Turns Off after about 1-11/2 minutes after turning it on then you need to replace your batteries in your remote control with BRAND NEW BATTERIES or it will keep doing it. It is a real pain in the behind especially if you dont have brand new batteries handy!
