Power issues. Just recently I've encountered a problem with my camera. After plugging it into my computer (And not noticing the power surge notification on the desktop while doing so). It locked up and powered itself off. I tried turning it back on, and it turned on for a split second then shut off without retracting the lense. I switched batteries and it retracted the lense, but I tried powering it on and the lense only came halfway out and it powered off. I've tried 4 fresh sets of batteries and the camera does nothing. When I hit the power button, but the green and orange lights on the camera flash once. (Unlike the low battery notification of 3 flashes).

Is this a new problem and this ran fine until now? If so, you want to make sure you have power going to the computer, power at power strip or surge protector, cables all plugged in correctly and tight. If all that checks out then the most likely cause is the power supply has failed. If you have had power surges or electrical storms recently this could be the cause. If not, your capacitors in the power supply could just be at the end of their life and died.

replace teh lamp its might have exploded if its okey check the power supply board but most likely the lamp needs replacement

Hi Gwendolyn,

First of all thank you for posting your question here at Fixya.
I'm assuming here that you're TV is a Vizio L32 HDTV.
My initial advice is to ensure that the AC source(outlet) is live. Please plug the unit to a known working outlet, if you are using a surge protector, directly plug the power cord of the TV to the outlet to confirm that the AC source is not the issue here.
If you've confirmed that the AC source is not the problem, then the fault is inside the TV and most likely the power supply. Most of the TV with a dead set symptoms that I've encountered is a power supply issue but of course needs to be confirm.

If your unit is not under warranty period (if so, avail it because the manufacturer will fix it for free, opening the rear cover will void the warranty), open the back cover, check the internal fuse of the power supply board, this is near where the AC power cord's directly connected. Check its continuity using the multimeter/ohmmeter, if you found it open, replaced it with a new same current rating that is printed on its body itself. Sometimes internal fuse fail due to voltage surge/flactuation, aging, etc, replacing with new one resolve the issue, however if the fuse blow again, this is an indication of more serious problem on the power supply board, it needs to replaced the entire board.
If the fuse is intact, you have to measure the output voltage of it through connector J1 (pin 9,10,11). You should be getting 5 Volts. If there's no voltage at these pin, you're power supply board is dead, replaced the entire board. If the 5 volts is present, replaced the main board.
I've provided you a links for the power supply board and mainboard below.

Hey Leo,

Unfortunately the problem you've mentioned is quiet common with your particular model.

Here's what Canon recommends, on its website.

-Turn the power switch to < ON > to turn on the power again.

And, if that doesn't work. Buddy, you'll have to drop by a service center. Hurry up, or you'll run out on the warranty period.

Toodles,

Unfortunately, it sounds like when the power was restored, the printer experienced a surge. If this was not plugged into a surge protector, then it's possible the switch was fried at the point of power restoration. It is important that with units such as printers, monitors, towers (computer), tv's, vcr/dvd players, almost any type of electrical appliance be plugged into a surge protector. However, even if this was true in this case - when a power shortage (outage) is experienced, it is necessary to unplug everything so that when the power is restored, nothing that is plugged in will be affected; as your printer was.
Now, you can have this fixed - either take it to a local computer repair shop; that might be able to fix it, or contact the manufacturer and inquire about sending the unit in for repair - regardless of warranty or not. If it is still under warranty, they may honor it. I am not positive they will for an accidental damage such as this, but it's worth calling them.
Please let me know if you need further assistance.

Monitor is erratic in operation - Power supply issue. Sooner or later the anomaly will become permanent and it will not power on. Just be ready for the eventuality.

Probably should be tossed. But you can try plugging a standard lamp into it. If it powers your good on that aspect but no way to know if surge pretection is still valid.

Before you actually replace the power supply, check some other things first:
1. Wall socket
2. Power strip/surge protector
3. Power cable
4. On the back of the computer, where the power cable plugs into, is the red switch set to 115? It should be 115.
5. Make sure that the power cable is not connected to a regular extension cord. Power cable must plug directly into a surge protector that is not daisy-chained to another power strip, surge protector, or normal (household) extension cord. Surge protector must be directly plugged into wall socket.

If none of the above solve the problem, open up the case and ensure that all power connections are secure. Also check ALL other components' connections. Any loose connections can cause problems for you.

If everything is secure and the problem persists, replace the power supply.

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.

I agree with first thought circuit overload.

I dont think it is the printer, I think it is your power supply in house. Just moving it to another socket does not change it from what might already be a circuit with a lot of load already.

You are experenceing surges that are normal operation ie at power on quatz lamp turns on reaching temp of 180 deg cel, then idles, if print command is issued back on comes the lamp drawing power.
