SOURCE: Display light is dark

I have seen this problem before this is caused by a failure of the backlight which provides illumination for the LCD screen. You may also want to check the inverter also since it fails often and interacts with the backlight.

SOURCE: Oil light comes on at certain times

You did check the oil level parked on level ground right? My guess is that your level is either low, or your sensor/oil pressure switch, is getting too sensitive, and may need to be changed. Unless you've changed grade of oil lately. When you stop, your oil in the pan, shifts forward in the pan & starves the oil pick-up momentarily, so if your switch/sensor for oil pressure looses pressure too much during that time, it turns on the light. If your due for an oil & filter change, have it done & make sure it's up to full mark on level ground.If that doesn't cure it, I would change oil pressure switch, oil sender, or oil pressure sensor, whatever it is referred to on your vehicle.

SOURCE: Dell inspiron 6400 display goes off < 1 min after switch on time

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

The buzzing sound is most likely the inverter problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Do you have sound? If you have sound and if the TV is responding to commands then I would say the main is fine. However if you don't have sound or video I would start with the power supply voltages. If you have sound and no video, I would suspect t-con but be advised, some manufacturers are building the t-cons into the panels !!!

Laptop on but screen black


Have you cleaned the fan, vents, heatsink recently? Does the Laptop overheat? Is the Laptop booting? Fan spins? Sound? LED's blink? I can tell much from the video. In a bright light can you see a "ghost image" of the desktop? Do you feel comfortable opening the Laptop? If so, there are a few things you can check.

No image 0n screen


Do a Cold-Start, remove any media, DVDs, CDs, USBs, printer cables, etc, unplug, remove battery, leave out during this process, plug in push on/off button, immediately start tapping ctrl+F-11 repeatedly until you get a beep or open the restor/recovery. restore to a date before this issue. You say "Boot up computer", does it boot?, HDD led blinks?, sound? Is there a "ghost image" in monitor under a very bright light? Has the laptop been damaged, dropped, jarred........etc? There is a tiny switch the turns the monitor on and off when you open and close the lid. It can get stuck. respod to this post for further assistance.

Aluratek at107f , unit won't boot up


Had the same problem with mine the other day. Go outside in the sunlight or use a flashlight. Touch the menu hard key. you should hear it click. Using the bright light, click on settings, go to display, and turn up the brightness. I know this sounds elementary but for what ever reason, this device, when it goes into sleep mode, will adjust the brightness settings down. Hope this works for you.

I have acquired a night owl monocular nightscope. the only number I could find was in the battery compartment # H3T-3M. there was a serial # 9846786. The problem appears to be the switch. the powerligt...


Yes, If you turned the Night Owl on during the daylight hours, or looking directly into bright lights.
If you have done this more than few time it could have damaged the image intensifier tube. If this happen to many times, it's finny, kaput, so long, it gone south, and gone bye-bye.

Looking at bright lights is damaging to NV devise. The intensity plate in the image tube, magify the existing light about 3000 to 8000 (radian light from the stars, moon and other light sources).
You have 80mm front lens on the Night Owl NOCP5. This mean that more light can inter into image tube.

Sir, have you been looking at bright lights, operate NV system during the day, have you? If not, there could be something else worng with you Night Owl. stewbison

Check whether the sound card drivers compatible with your present operating system. if your Pc built with Vista OS. then Get a vista driver from its official website.Some times When you install any devices or driver that might change the system files. even it may corrupt the files due to its incompatibility. Some mother board and Bios does not support some type of Sound cards . if your Motherboard has onboard audio .then disable it through Bios utility. uninstall the sound card,drivers. Remove the Sound card. REplug it. Restart the Pc. this time you can get add new hardware window. install the drivers. if problem still persists contact service centre.

thank you !
