Today my power went out for a split second and came back on I turn my TV back on it makes a high pitched whining noise and the screen wont turn on. Cant add picture but model number is MW30G71.


unplug your tv. let it sit for a good bit. 1/2 hour did your power just go out or did you have a power surge then no power. surges cause the grid to go down for a second too and that causes problems too. surge protectors are good for everything. also are you on cable? if so have the cable company check they're filters into the house may be an issue but check the tv after a half hour unplgged and then plug in and turn on normally? sometimes it needs a reset time period before the fuses inside will reset themselves.

Samsung HLR5667wx/xaa. Power surge took out tv. Replaced bulb and the bulb works, but tv wont come on and lamp light is flashing.


Hello, it sounds like the color wheel may have failed. Was there any noises, like a high pitch sound before it went out? If the color wheel isn't turning at proper speed, the set won't start up by shutting down the lamp protection circuit.

When turning on my emachine desktop the monitor states no signal someone suggested that I need a fuse, Where would that fuse be located?


hello if the monitor wanted a fuse .. then it wont turn on.. which means its getting power !!!
you problem is the pc ,or monitor cable fell out at the back of pc, or you may have a defective memory stick ,that if the pc is getting power and you are seeing light on the pc.. if the pc is dead nothing lighting.. no beeps, not even the optical not opening then you have a power supply problem,
if u had a surge be it went dead try this, unplug system for 5 mins, the plug it back in, try powering on.. if still nothing , most likely , memory,video card or power supply is defective, but i think. its your memory if getting power

Computer won't turn on won't do anything , i had it connected and someone at my house was using electric drills and the fuse tripped and everything was shut down including my computer and since then it...


Try unplugging the computer completely from the wall for 15 minutes. Plug it back in, and see if it will power on.

If it doesn't it's most likely a blown power supply, when the breaker tripped, everything on the circuit basically fed back into everything plugged in. This is something most computer power supplies do NOT like.
The good news is, a power supply is generally pretty cheap, you can get new power supplies atarting around 20 bucks, although decent quality ones are closer to 50 bucks. Bad news is, there is about a 1 in 20 chance the power supply took other parts with it.
Once you do get it running, or get another computer, make sure to get a surge protector strip and plug everything connected to the computer into the surge protector. A 15 dollar surge protector can save you 150 dollars in parts and labor. (or more)

The power went off in my house for 15 minutes. When it came back on everything worked except the Gateway PC with Windows XP and the monitor which was connected to a surge suppressor. The PC won;t come on...


If the monitor is out as well then the surge suppressor did its job and took the hit, basically rendering it useless now, try plugging in the system and monitor directly to the wall, it they work then you need to replace the surge suppressor.

Raidmax 500w power slowly died, then wont turn back on.


1.-Your CPU fan is working?

2.-Your Power supply fan is working?

If not and following your description I think that you have to replace your power supply.

If you have the light on in the motherboard doesn't mean that your power supply is good.

Check the first to points above and if 1 and 2 are not working

Replace your power supply.

Let me know how it is going!

Thank you for using FIXYA!

How old is your computer? Did you recently have a power outage or anything? Most the time if a computer won't turn on, something in it went bad OR an outlet is bad. Try this:

1. Make sure that the power switch is on, the switch in the back (on the power supply itself) is turned on, and everything along those lines is functioning.
2. If that doesn't work, and it will not power on AT ALL, make sure the cords are plugged firmly in place, including the surge protector and/or the power cord itself.
3. Try resetting the surge suppressor and/or plug the computer into a different outlet in the surge suppressor. Try other items in that surge suppressor (or even in the wall outlet, if that's what you're plugged into) to make sure that the outlet itself is working.
4. If your computer is plugged directly into a working wall or surge suppressor outlet, try a different power cord.
5. If your surge suppressor works, your wall outlet has power to it, and you are using a known-good power cord in the computer, you will have to go into more in-depth investigation as something inside the computer likely went bad. It could be the video card, motherboard, CPU fan, power button, or the power supply itself. Start by testing the video card and the power supply by (one at a time) swapping out a known-good component for the one you suspect may be bad. If it won't turn on after that, try swapping out the next and try it again. If it still will not work, it could be something more serious such as the motherboard or power button.

Good luck!

it could be a bad power supply or a bad motherboard. Other problems might cause issues, such as a bad video card.
