Im a user of Laptop nc6230 for long time , not i found a problem with my laptop. Same time when i switched on the laptop, i can hear everything sound,fan but the screen remain blank. And some time it...


@rashid386

If you turn the computer ON and you can hear that something's running on the background but there's no display , this is a sign that the screen's FL Inverter (this is the chip that controls the backlight of your LCD) or the LCD screen itself is already wearing out and needs to be replaced. If you can see a background image but there's no backlight - you need to have the FL Inverter replaced. If the screen is all black, you may need to have the LCD screen replaced. If you know your way around the computer, you could order screen replacement here and disassembly guide here.


Good luck.

At first my ps3 only showed the background screen without any icons, but after I switched it on and off severally, it no longer showed anything on the screen i.e the screen remains blank


SAFE MODE:

1. Place you finger on the on/off sensor leave it their until you console turns off then take you finger off the sensor.

2. Place your finger back on the on/off sensor leave it their until you hear 2 consecutive beeps then take your finger off.

3. Once the safe mode screen comes on select the option PS3 SYSTEM RESTORE.

NOTE: A PS3 system restore will delete all data except the OS. I recommend backing up your console onto a USB flash drive if possible.


Good Luck!

HP L1706- screen is blank when I switch on


First if you have a extra monitor try to plug it in and see if it works. If not then check your video card. or get into the computer and try and remove and reseat the memory. Sometimes by just doing that can solve the problems

Cell phone (Sony Ericsson W910i) turns itself off every 30 seconds


i have one too and it always turns itself off at least 15 times a day and a red light comes on at the back and the screen is blank. It hangs up on people half way through phone calls, and tells me i have messages wich i don't and comes up with blank messages which i can't delete!! Today it has done the exact same thing again but it has been frozen for over 3hours i have tried taking the battery out and nothing works :(

Blank Screen


ccfl ( cold cathode flouroscent lamp ) is the backlit feature of the lcd panel. If you see a blank screen but do see the output on the external monitor then you sure have to take it to the hardware tech to get the inbuilt LCD panel checked. it seems to be a electronic failure. Thanks Ashish.
