When you press the power button, it will click and you will hear sound, but that sorta staticy sound that happens before the screen turns on doesn't happen. If you continue to turn off and on for awhile eventually the screen will make the staticy noise and turn on.

the tv need for servicing, the cause is either bad regulator transistor in the power supply section or shorted horizontal output transistor. that is why the main circuit board doesn't get to turn on. to do the repair just ensure you have knowledge in repairing tv.
Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.
Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.
When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?
Anything shows up on the LCD Screen?
If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.
If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.
Be more specific. Turning off when? What happens when you try to turn it on? When you have the power cord plugged in do you see any lights? When you press the power button do you hear the fan running, hear the hard drive running, see anything on the lcd screen, hear the cd drive Click once, see the light on the cd drive drawer turn on for a second or two when it clicks, hear any beeps or blinking lights?
You need to be more specific and tell what happens when you plug in the power cord and press the power button. There are a number of reason why a computer will not boot, but if you tell what's going on someone can help you.
Computers don't boot for basically the following reasons, 1) the power supply is bad. That means when you plug it in you don't see any lights, and when you press the power button nothing happens, you hear no fans, no beeps, no blinking lights, no hard drive spinning, no cd drive clicking and nothing appears on the lcd screen.
2) A motherboard issue, usually when this happens you will either see blinking lights or hear beeps. Those blinking lights and beeps are codes that tell the technician what is really going on.
3) Static Buildup - try removing the battery and the power cord then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back in (leave the battery out) and Press the Power Button. If it boots up you had static buildup and can replace the battery, count your blessings and Thank The Lord cuz a dishonest repairman would have told you he had to replace the motherboard for $300
You probably and lets hope so, have an Electro Static Charge Buildup on your desktop. Remove the Power Cord and Press and Hold the Power Button for 30 seconds. After 30 Seconds plug the Power Cord back in the hit the Power Button. If it boots then you had an Static Charge Buildup. If it does not boot and you say it happened after a power surge then either your Power Supply or Motherboard is possibly damaged. Do you hear fans, hear the disk drive running, see lights, hear the CD Rom click once and see the light on the CD Rom drive com on briefly after you hit the Power Button. If so it would seem that your power supply is ok.
When you powered on the machine did you hear any beeps, hear the fan running, the disk drive running, lights blinking, hear the cd drive click, see the light on the cd drive door for a second or two when it clicks? If these things are happening you are getting power. If not, your problem might be with your power supply, hard drive or motherboard. Remove the power cord, then press and hold the power button for 30 seconds, then plug it back in and press the power button. if it boots you had a static charge. If you get nothing at all but a silent system your power supply is bad. If it sounds like your computer is running but you can't see anything on the screen you might have a problem with your screen or video card. If you have another monitor try using it and see what happens. if it works so you can see things then your monitor was bad. If it does not work with another monitor but you still hear fans, and see lights and hear the disk drive spinning, then your video card is probably bad.
