Problem with my laptop display

How to fix a blank screen in 60 seconds: Fix Sanei N10 blank screen in 60 seconds

Just insert the cd of an OS and see if it displays something.....
If it becomes blank again then I think your PC's display has gone..

It seems that either the display for the laptop is going, or the video card is. Is the computer's power light still lit when the display blacks-out?

wich page is blank internet explore or windows.
pls type corectly u r problems.

The backlight is the light bult that illuminates the screen. Before it finally goes out completely it will turn your screen a pink color on startup (and then usually become brighter and the pink fades). It is also possible that the backlight, also called a Cold Cathode Flourescent Light, CCFL, died an immediate death. But usually they take a while and signal with the "PINKNESS" first. If you found that your computer is working just fine connected to an external monitor (and you moved the base of your laptop around while connected to the monitor to be sure and left the computer on for a long time) then you have verified that the screen is the problem. It is usually two things: (1) the inverter, a circuit board that increases the voltage to supply the LCD which eats around 700 volts (yeah baby); or (2) the backlight itself. The first problem is a relatively easy and inexpensive fix. You can find how to replace an inverter by downloading the Hardware Maintenance Manual for the T40, T41, etc., from IBM/Lenovo's site. Replacing the backlight itself, a bulb that is like a strand of speghetti and even more delicate, is a tougher job. I would suggest purchasing a replacement screen in that event rather than replacing the backlight yourself. (The HMM probably does not show you how to replace the backlight/CCFL as it is a potentially dangerous job.) That suggestion assumes you can find a cost-effective replacement screen and do not mind opening the TP and putting the new screen in. At least look at the HMM to see what is involved. Good luck.

First of all, you have to check whether you can see video signal with surrounding light tilting the screen.
If you can see dim image, all you have to do is replace back-light inverter or fix it. Usually, the fuse is open and you can connect it by simple soldering.
If you can't see dim image, it is another problems.
Give it a try.

take out the RAM of your laptop, put it again,
also check the display on external monitor through vga port

when i turned on my K750i display is recently white blank for few sec and then become black for few sec again and only so. Nothing else appear on display what i should do? Help me please!!

So, if your motherboard is turning on and the fan comes on than for now you can check to see if your back light turns on for your lcd panel by going to a dark place and turn ont he laptop there. Than check if you see a faint light that stays on or a flicker. If you see a faint light or the display is dim than it is the inverter on the lcd panel otherwise you may need to replace the video card which can be integrated onto the motherboard and may require a new motherboard. All depends on the model you have.

the front panel display initializing and then disapear and then the functional buttoms begin to flash. nothing happen again. when i press the on buttom the same thing reocurre
