Probably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/daughter or addon card(s)..

..plz do check the following as in order:..
the Hardware part:..
1)a) inpower on mode, open/unplug the data/vga cable of the monitorfrom cabinet..see if raster or 'osd' is appearing on the monitorscreen..if so monitor is ok..else replace the monitor and see..[notapplicable in case of laptop]..
b) in case of laptop try to getoutput from external display unit/monitor using vga port..if there'sproper display in there..the problem is probably with either the 'lcd'or 'ccfl' or 'inverter circuit'..

2) if u hv a graphics card, replace with a standby or onboard and see..[not applicable in case of laptop]..

3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

4) see ifthe ram(s) is loose/faulty..open clean/remove carbon & oroxide formed on the teeth with an eraser n resit it..or replace with astandby n see..

5) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..

6)remove/cleandust neatly..dust is non-uniform in nature n may cause jam/shortcircuitry/excess resistance n many more..resulting an increase in heat..

7)open the CPU Heat-Sink with fan out of the socket..put some "Heat SinkCompound" (available in local electronics chip level spare market)between the cpu/processor and the CPU Heat Sink *** fan..resit/fit ittightly in position..

8) on main/mother board..see with a debugcard for mb error..may b short..look for defective capacitors(espabove1000mfd)/mosfets..go through the mb's south bridge n the circuitlie around atx connector..the crystal clock generator (if cpu isn'theating up)..

9) [in case of desktop] the smps itself may bdefective/faulty..check the outputs of smps viz. 0v (black~ground); +12v(yellow); +5v (red, green~ps-on, violet~pg& grey~sb); -12v (blue);-5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic',or pwm switching regulator circuit..look fordefective protector-transformer/resistance (esp 4.7k)/mosfet..
check the battery n adapter [main power], in case of laptops..

the Software part:..
1) hva licensed and UPDATED antivirus installed (i prefer avg/kaspersky,remember, without updation a full version antivirus is useless)..

2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..

3) download n run Startup Control Panel..http://download.cnet.com/Startup-Control-Panel/3000-2094_4-10039330.html..'remove allthe unnecessary startup items from here..(if u can't find what toremove, post me/us in ur comment with all the items listed in each nevery tabs herein)..

4) remove all unnecessary software from add/remove programs..

5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html..

6) disable the following:..
a) 'AutomaticallyRestart' right click onmy computer->properties->advanced->startup nrecovery->(un check on the) Automatically Restart;
b) 'ErrorReporting' right click on mycomputer->properties->advanced->errorreporting->disable error reporting->(uncheck on the) 'but notifyme when critical error occur'..

7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880

if u r not a professional, always better to seek advise from ur system admin/vendor....

Have power but no Display


Bonnin, Can you see a faint image on the screen? Have you tried to hookup an external monitor?
IF you can see a faint image on the screen, and a normal image on the external monitor, you have a bad power inverter (for the lcd screen) or a bad back light (in the lcd screen).
Take laptop to a shop to have them verify.
Hope this helps.

Black screen on laptop


When it is in that state, try hooking it up to an external display. Also look for a extremely faint image on the screen. If it's really faint you have a bad back light, if you see nothing but you get a display on an external monitor it's probably the display going bad.

Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

ACer Screen is pitch black, but system runs normally


Check if this will work on an external monitor, if it will, you can point the finger at the following:

  • Inverter failed: If you cannot see any image on the screen even a faint one, replace the inverter
  • Backlight gone: if you see a faint image on the screen, the screen needs replacing
  • Possible failure (unlikely) of the vga cable
If it will NOT work on an external monitor, the graphics chip on the motherboard has failed.

Solution for "my laptoop seems to want to boot but when is is done booting the screen turns black and remains that"


If the laptop appears to boot up and you can't see an image on the screen, you need to determine if the screen is faulty or the video card.
Connect an external monitor to the laptop's external video port, power up the monitor first and then boot up the laprop. If you get a normal video image on the monitor then the video card is OK and the fault is with the LCD screen.
If you don't get an image or POST information, then the LCD screen could be faulty or the laptop didn't boot up.
Please get back to me with the results of your tests and any error messages etc. so I can advise further.

Connect an external monitor to the notebook. If you have video then it may be your LCD has gone out. Sounds you just purchase the notebook it should still be under warranty. Call the manuf. and tell them your LCD has gone out. They should fix it for free. Most new notebooks/desktops come with one year warranty.

I hope this helps.

It's all black


If you power it on, take a flashlight and shine it on the lcd at and angle and look real close to see if you can see a faint image. If you can, then your backlight in the screen is not working.
Also, you can attatch an external monitor to it, while its off, then power it on and see if it lights the external monitor. Try that and let me know your results.
If you get a picture ok on the external, and you can see a faint image on the lcd using a flashlight, then it could be the backlight inverter board or the bulb itself inside the lcd went out.
If you don't get any picture at all, using an external monitor and can't see a faint image on the lcd using a flashlight, then I would say there's other problems with the laptop itself. Could be a mainboard problem, power issue, etc..
