Turns off after a few seconds

All of a sudden there is this problem, it was working perfect last night. There was no power outage or anything like that during the evening. When I came to the TV this morning it would not turn on at all, the base nor with the remote. I unplugged it and waited a few seconds, then plugged it back in. When I hit the on button it powered on like normal, then 3-4 seconds later, by the time the picture was just coming visible. There was a click and the TV shut off by itself and it will not turn back on at all. I can repeat this process of unplugging, re-plugging to any outlet, turning it on, waiting a few seconds, it powers off and will not power on again until I unplug and replug it in. I opened up the back and took a look around, nothing felt loose and it never gets moved around the room. I blew air everywhere to clean it out and I could not see or smell anything funny. Any ideas?

I am having the exact same problem. Are the solutions mentioned in this post (replacing HOT/FLYBACK) something only a technician should attempt? Or could someone with relative knowledge of circuits e.t.c attempt this? And if so, where could someone find affordable replacement parts for this? Any reply is appreciated. Thanks.

The unit is going in to shutdown. There is a short in the unit. My guess would be the HOT and or Flyback are bad.

Power cut last night and cannot get my TV to power up.

First check your circuit breakers. Also,If you are capable, open the TV and check the fuse inside. The power outage and the sudden spike in power might have tripped the breaker or blown the fuse. Good luck!

Refrigarator not working after power outage

When power goes on and off suddenly, it can cause the compressor to overload and "trip out" This is supposed to protect the compressor from being electrically damaged. In most cases, after 10 or 15 minutes, the compressor will reset. It is usually safer to switch off the fridge or unplug it for 10 to 15 minutes to ensure a full reset. If it doesn't start, the power surge may have damaged the compressor relay. or overload device on the side of the compressor. I would doubt that it damaged the compressor itself. Be aware of the relay and overload device, unfortunately, there are Techs who will quote for a compressor job when all it needs is a relay or overload.

Yamaha RX V671 will not turn on anymore after a power outage

The protection mode has activated.
Reset the protection mode as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

I have an HP 7280 all in one. Worked great for a couple of years and now I have blinking lights and a code on the screen. The code is B0539F38 and sometimes it is 00729C8. I was able to reconnect it last...

You need to pull the right side panel off, remove the motherboard, pull the coin cell battery out for a couple of seconds, put it back in and back together. Your issue will be solved.

Wii stopped working . We played it before bed one night and the next morning there was no light on the system and it would not turn on. We have unplugged everything and plugged it all back in...still...

This probably didn't happen, but my guess is that, when the sudden power was restored, the Wii console took too much and fried the circuts. This can happen on on computers, but I'm not sure about gaming consoles. This can be prevented with a surge protector, a device with several power outlets and a switch for power protection. If the warranty on your Wii is still present (I think it lasts 1-4 years) you can send it in to Nintendo for repairs (or if they can't repair it, they'll send you a brand new one).

We had a power outage last night while the tv was on. now i cannot turn it on. when i press power the light turns green for a second and goes back to red.

Check the capacitors for any bloating on the power supply board, and replace with exact value. Please don't run the TV 24/7!

Good Luck!

No Power to my TV after power outage

A lot of times its simply a fuse that goes out. Either way someone is going to have to open it up and inspect the fuses first. It 's a fairly inexpensive service call.

Hopefully the fuse took the hit from the storm.
