It's a dreadful way to start a day - you press the power button on your computer and nothing happens. Do not fear because all may not be lost! Follow these simple steps to determine why your computer won't turn on.

Note: It is very important to troubleshoot any issue beginning with the most likely and easily testable problem so be sure to follow these steps in order.
Difficulty: Average
Time Required: Anywhere from 10 minutes to a few hours or more depending on why the computer won't turn on
Here's How:

As silly as it may sound, the number one reason why a computer won't turn on is because it wasn't turned on! Before starting a sometimes time consuming troubleshooting process, make sure you've turned on every power switch and power button associated with your computer:
Power button/switch on the front of the computer's case.
Power button/switch on the front and/or back of the monitor.
Power switch on the power supply on the back of the computer.
Power switch on the power strip or surge protector (if you have one).

Verify that the power supply voltage switch is correctly set. If the input voltage for the power supply does not match the correct setting for your country, your computer may not power on.

Check for loose computer and monitor power cable connections. A loose or unplugged power cable is one of the top reasons why a computer doesn't turn on.

Perform a "lamp test" to verify power is being provided. Your computer isn't going to turn on if it's not getting power so you need to make sure that the power source is working properly.

A damaged power supply could be preventing the computer from being properly powered.

Do a quick test of the power supply by holding your hand behind the power supply fan located at the rear of the case. If the power supply is working, you should feel air from within the case blowing against your hand. If not, you may need to replace the power supply.

Tip: Is the power light on the front of the computer's case on? If you've turned the power switch on but the light is off, this is another good indication that the power supply is the cause of this issue.

Over time, internal components and the cables that connect them can wiggle loose which can often times result in a computer unable to power on. Try reseating the following and then try to power on the computer again:
Reseat the internal cables
Reseat the memory modules
Reseat the video card
Reseat other expansion cards

Reseating the CPU may also be necessary but should only be attempted if the reseating of all other components is not successful. This is due to the fact that this process is a little more involved and can run a small risk of damage to the CPU. This isn't a big concern if you're careful, so don't worry!

Check for causes of electrical shorts in the computer case. This is often the cause of the problem when the computer powers on for a second or two but then powers off completely.

Most monitors have a small light next to the power button that can change between various colors. If the screen is blank, this light is your main source of information about the monitor.

If this light is not on at all, double-check the power switch and connections (Steps 1, 2 and 3) and also make sure the monitor cable is securely plugged in to the video card port on the back of the computer case. If the light is still off, replace the monitor. If it comes back on, try starting your computer again - a loose or unplugged monitor cable may have been the issue all along.

An amber or yellow power light simply means that the monitor is not receiving any information from the computer. In and of itself, this doesn't tell us much.

On the other hand, if the light is amber or yellow, the computer power light is on, and the hard drive is active (making familiar sounds and the hard drive activity light on the computer case is blinking), the computer is probably starting normally but the video card is not sending information to the monitor. Replace the video card.

Beep codes (see Step 11) usually sound when a video card has malfunctioned but this is not always the case.

Is your computer making a beeping sound? Sometimes a computer will turn on just enough to play a series of beeps from the speakers.

These beep codes play in particular sequences and represent a specific problem that your computer is having. Troubleshoot the beep code to figure out what it's saying and then service the computer as necessary.

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



Note: The front panel buttons must be used, NOT those on the Remote Control.



• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.



Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

Need to fix G62 computer:will not start


"Worked in the past, doesn't work now", That's sort of the definition of a failure. Has the laptop been dropped? What does the laptop when you try to start? Do you see LED"s blink? Fan spins? HHD LED blink? Battery light on? Has the AC jack been damaged due to pulling on the cord? Did you try a cord/charger with the EXACT same power spec? Test the DC volts at the laptop cord plug with a multimeter. Reseat the Memory mods. May be a HDD failure? Post results

Just had to reatach my fan back over the processor but i took the mother board out and my wires came off the mother board which where for the power switch and the reset button, can anyone tell me which...


Hello Sir, hi, the wires on your casing are usually labeled, like in the picture below: cyberdyers_0.jpg

the power led green wire goes to the power led + and the white goes to the - . Now the HDD + goes to the HDD + the red wire, power switch can be interchange, same as the reset switch.

I have a Mitsubishi WD-62525. This morning my TV would not turn on so I pressed the rest button. After the Timer light stopped blinking I pressed power. I could hear the fans start than a somewhat loud...


the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note:
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.


and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure
