You should check the lamp. The cracking sound is the ballast trying to fire the lamp. The part number is TY-LA1000 and can run up to $275

I have a 46" Samsung LCD tv that won't turn on. When I press the power button you can hear the chime sound it usually makes and you can hear the relay click and the screen flashes quickly then goes bl


sounds like you have a back light problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flash light on the screen. If you see the faint picture on the screen, you have a back light problem. You could either have a shorted inverter that is pulling down the 24vdc line, a blown CCFL back lamp, a high voltage short (arcing) from one of the inverter outputs, or a faulty 24vdc power supply

Heard a pop when I turned on tv and now nothing


don't leave it on and have it looked at---most likely is if it uses a lamp that may be the problem but if not it may be in the power supply.

No display after reboot windows


If it seems like your system is running whereas you hear fans running, hear the hard drive running, see lights, heard the hard drive click during bootup, but there is nothing on the lcd screen then try the following:
1) Try hooking a external monitor to your laptop. It can be any type of monitor even one of the old style fat crt monitors as long as it has a vga cable to connect to the laptop. There is a sequence of keys you might have to hit to get the display to show on the external. Most times you hit the FN (Function key) and hold it while you hit the corresponding F1 thru F12 key that is for display. Usually the correct key will say CRT/LCD or it might have a display icon on it. If the image displays on the external monitor that means the video card is good.
2). Remove the external monitor and reboot the computer again. Now when it is done booting take a flashlight an shine it on the lcd screen. You are looking to see if you can faintly see the icons on the screen. If they are there but barely visible then the LCD Inverter is bad. The LCD Inverter is located at the bottom of the lcd screen just above the keyboard and the Strip around the lcd screen covers it. You'll have to take the lcd apart to get to it.
3) If you don't see anything when you shine a flashlight on the desktop, then the lcd screen has to be replaced. However, sometimes the cable on the back of the lcd screen has come aloose or just needs reseating, so unplug the cable and put it back then see if it shows an image.


Read Below if it is not booting at all when you press the power button.
Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

TV made a big popping sound, and then a crackling


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of the color wheel:The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

No picture (black screen); making popping/crackling sound


there is a possibility that the semiconductor in power supply side damaged due to electrical surge. more likely the STR IC of Diodes.

Dell monitor blank. nothing appears on screen. light is blinking by minitor power button, but nothing at all on screen. I hooked up to my laptop, still nothing. Checked power/ tried new power cable. No...


Make sure you set up your laptop to display to a second screen. Depending on your Operating system, go to your display properties and go to the settings tab. Then click on the second monitor and enable it.

#1 When I turn on the TV the power button comes on then blinks 6 times then goes off for a few seconds then repeats the cycle. I have sound over my surround system during this time but no picture.
#2 My sound would crackle and pop every once and a while until now it does nothing. I have to watch it with the surround sound on.
