Where you plug in the power cord the light stays on and the screen don't even turn on i need help findin the problem.

At this stage, try replacing ps Caps. Old elements had cap problems in ps area.

My Samsung started doing that and it got worst and worst. Searched the web and find answer. It was the high voltage circuit. All TVs now are like computer and it check for 390 to 400 volts and if it is below, the TV will not turn on. Good thing the Samsung has only one capacitor showing the high voltage circuit. Measure the voltage was 381 volts. The capacitor was rated at 100 uf at 450 volts. From some old TV and power supply, got two capacitors rated 150 uf and 220 uf both at 400 volts. Had to connect them in parallel and took out the old capacitor. Now, my TV works fine.

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.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

Take a flashlight and shine it on the screen and look very hard and you might see the icons or something very faintly on the screen. If so, your LCD Inverter needs to be replaced. It is located at the bottom of the screen and covered by the strip that goes around the screen. IIf you don't see anything on the screen then try plugging an external monitor to the laptop. I can be any kind of monitor, even the old big fat crt's as long as it has a vga cable that can go into your laptop's vga port. If you see the image on the external monitor, that means your video card is good and the screen needs to be replaced. Sometimes you might have to hit the FN key plus one of the F1 thru F12 keys to get the image to display. The correct F1 thru F12 key will either say CRT/LCD or it will have the icon of a display on it. Press and Hold the FN key then hit the correct F1 thru F12 key. This will toggle the the image to display either on the computer's screen, the external monitor screen, or on both screens.

When you plug in the power cord do you see any lights either on the power cord's adapter or on the computer that indicates that the power cord is plugged in? If not, your power cord might be bad. You might have been running off your battery for the last time you used it and since the power cord was bad it was not charging your battery so it eventually drained all battery power.

When you turn it on do you hear any fans running, any hard drive running, cd drive clicks once and you see the light on the cd drawer come on for a second or two, lights anywhere on the computer? If so these are signs that the computer is trying to boot. If not you might have a motherboard issue.

Static Charge Buildup can also cause the computer not to boot. Remove the power cord and battery from the laptop. Press and hold the power button for 30 seconds then put the power cord back in (leave the battery out) and try to reboot. If it boots, you had a static charge buildup and can put the battery back in now.

Is the computer actually up and running but the screen is black? If so take a flashlight and shine it on the black screen. If you can bearly see the icons on the desktop that means your lcd inverter is bad and needs to be replaced.

If the computer is actually up and running but the screen is black, try hooking an external monitor to the laptop. You can use any type of monitor, even the big fat crt monitors as long as it has a vga cable to plug into the laptops vga port. You might have to press the FN (Function Key) and one of the F1 thru F12 function keys to get the image to display. Normally the correct F1 thru F12 key will have CRT/LCD written on it or it will have an icon of a display. Press and Hold the FN key then hit the correct F1 thru F12 Key to display the image on the external monitor. If it shows, that means your Video Card is ok.

If the computer is on and running but the screen is black, you don't see any icons on the desktop when you use a flashlight then your lcd screen will probably need to be replaced. It might be something as simple as the lCD Cable is loose or just needs reseated (pulled aloose then plugged back).

You'll have to take the screen apart to get to the lcd inverter and the lcd cables.

Does your laptop even begin the boot process where it displays stuff on the screen? Do you hear fans running, disk drives running, see lights, hear the cd drive click once and notice a light that comes on the cd drive door briefly when you press the power button? If not you computer either has a bad power cord, a bad dc power jack where the power cord plugs in, a bad mother board or static build up. 1) lets eliminate static buildup by removing the power cord and the battery then press and hold the power button for 30 seconds. Then replace the power cord but not the battery and hit the power button. If it boots up you had static build up. 2) Take an ink pen and put in in the slot where the power cord plugs into the laptop, if it wiggles loosely then your dc power jack which is soldered onto the motherboard needs to be replaced. 3) If the power jack is tight and when you plug in the power cord if you don't see any lights or hear a fan, disc, cd drive, then you can almost bet your power cord is bad. 4) If the power cord is ok then you have a mother board issue. Normally motherboards will give some beeps or constantly blinking lights when you plug in the power cord and try to boot up. These beeps or blinking lights will tell the technician what is wrong with your computer.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

The Slight pop will be when the cors plug contacts the plug on the TV, and just a warning it is very dangerous to yourself and detrimental to any electrical appliance if you do this. when plugging in you should make sure everything is switched off before doing so and once all cords are connected you can then turn the power on. As to your problem I think you may have cooked your power supply inside your tv. You may need to have a technician look at it and diagnose for you. Hope this Helps.

Do you get an Amber light on either monitor?
