Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

There is a k nown issue with this model with a op amp failing. It causes the video to shrink and expand and in some cases the TV will shut down and not have any video. Its a common problem and not bad caps in the power supply. You can get a fix for this from www.TvRepairKits.com

Computer won't turn on.


There must be a problem with your power switch on your computer casing, or motherboard or power supply.

Detach your power supply and try this, to check if your power supply really works. If the auxiliary fan will turn, your power supply is good

25627818-lfqggqo5gl3n2v4xynrvsb5u-5-2.jpg If the cpu cooling fan and power supply did not turn the fan, but you have checked already the power supply that is working then you can conclude that your motherboard is need to be replace. But the power supply and motherboard and working, meaning to say your computer casing need to be replace or try fixing the contact of the switches attach to your casing.

Have a good day.

My power supply is blinking orange when i put it in the xbox 360 what do this mean.


Hello.An orange light is illuminated on the power supply for one of the following reasons:

a The console is turned off.
b The power supply is disconnected from the console.
c The power supply cord is not fully inserted into the power socket of the console.
d The power supply is faulty.
e The console is faulty. (The console might be faulty if it does not turn on when the power supply light is orange.)


The power supply has several built-in safeguards to help prevent damage to either your Xbox 360 console or the power supply itself. The power supply will automatically turn off if either the current flow, the voltage, or the temperature is too high. When the power supply turns off for any of these reasons, the light on the power supply will turn from green (normal) to orange or to red, or the light will turn off. When the power supply light is green, the power supply is working correctly. What you are experiencing is an over heating issue, that may have damaged the supply.

With that being said, i would try to reset the supply by disconnecting the unit form the console, and unplugging the power supply unit form the wall socket for 5 minutes. Once the 5 minutes have passed, reconnect the unit to the console, and plug the power supply into the wall socket. If the console dose not power up, and the supply unit is still showing an orange illuminated operating light, this will confirm that the power supply unit will need to be replaced. Contact Microsoft for the correct replacement parts needed(power supply unit)


TIPS FOR PREVENTING OVERHEATING ISSUES

1 Do not block any ventilation openings in the power supply.
2 Do not put the power supply on a bed, on a sofa, or on any other soft surface that might block ventilation openings.
3 Do not put the power supply in a confined space, such as a bookcase, a rack, or a stereo cabinet, unless the space is well ventilated.
4 Do not put the power supply on a stereo speaker, an amplifier, or a heat source such as a radiator or a heat register.
5 Do not use an unlicensed accessory, such as a replacement power supply that was not manufactured by Microsoft, or any accessory that plugs in between the Xbox 360 console and the power supply.
6 Plug the power supply directly into a working wall outlet. You may have problems with the power supply if you use an extension cord or a power strip if the extension cord or the power strip is faulty or cannot supply the required power to the console.
7 If you are not sure about the reliability of an AC power outlet, power circuit, or power cabling, do not use it. Contact an electrician.

The t.v powers on for just a second and clicks off. I can hear a click from the back and it recycles off/on over and over.


open the set remove all but the ac cord connectors from the power supply; label them first! turn on the tv if the power supply does not recycle turn off the set and, connect and, disconnect each cable one at a time going to the power supply turning the set on and, off each time as you test until the power supply cycles (fails) again then repair or, replace the circuit board that causes the power supply to fail. if the power supply cycles on and, off (fails) with all connectors but, the ac cord disconnected repair or, replace the power supply.

Nothing on my computer was working. Screen and disks not working. On and off on power supply doesn't turn on fan. I pulled power supply out. Should the fan go by just plugging into the socket and turning...


This has to be plugged into a motherboard and the switch to it as well is controleed by motherboard so no it will not come on just by applying power. I would try another supply for you inital issue if that does not turn on then what you got here is a cable backwords or a motherboard malfuction of some type.


thanks if this helps please rate it.

When i turn the power on the green power supply light goes out and doesnt turn onand the computer wont turn on


Follow these:
  1. Unplug the computer.
  2. Disconnect the power supply from the motherboard and all other accessories.
  3. Replug the power supply.
  4. Connect the green wire (PSON) of the power supply by way of a jumper wire to any black wire (ground).
  5. The power supply should turn on with its fan. If not, it is defective and should be replaced.
  6. Check the ATX12V connector of your motherboard. It is were you removed the 4-wire, 2 yellow and 2 black, connector of the power supply. Check the continuity of the yellow wires to the black ones. It should be open, otherwise it is shorted and your processor is defective and should be replaced.

I just installed a 500W power supply in my Dell dinension 4600i. Now it will not even turn on.The switch on the Antec power supply is on. All connectors are hooked up.


Hi

Does the power supply fan turn? When you first turn it on does the power supply fan twitch? You need to use a power supply tester. This will test the supply under load. What were the symptoms that made you decide to get a bigger supply? Is this a clone supply? I have seen cases of clone supplies not working in OEM equipment. Usually requires a simple wire change.

I cannot get my w3611 machine to turn on, what can I check?


Replace the power supply. 70 to 80 percent of the computers that come to my shop are dirty inside, and the power supply has failed because of this.

Even if you get a green power light, your power supply isn't supplying enough power to turn the processor on.

All the lights use less than 1 Watt.
EACH fan uses 2 to 3 Watts
Harddrive just sitting there spinning, uses about 3 to 5 Watts.
When it's time for the processor to turn on, the power supply can't handle it. Not enough power! Processors use 55 to 125 Watts, depending on the processor!

FLASHING RED LIGHT ON 360


Make sure that the power supply is cool loadTOCNode(2, 'whattotry'); The red light may indicate that the power supply is too hot or it has already overheated. If that is the case, you should let the power supply cool for several hours in a well-ventilated space. Turn off the Xbox 360 console and don't turn it back on while the power supply is cooling. This will allow the power supply sufficient time to cool. As soon as the power supply has cooled off, the power supply light will change from red to orange, and you can turn the console back on.

If the power supply light is still red after you have let the power supply unit cool in a well-ventilated space, the power supply unit may require replacement. You can contact Xbox Customer Support at http://www.xbox.com/support/contact (http://www.xbox.com/support/contact) for information about how to replace the power supply.

Make sure that the power supply is plugged in correctlyFor further details go to this link
