Re: Screen blanks sporadically

This could be a video issue or a screen issue. To determine which one try to plug it up to an external monitor. If it does not black out on the monitor then it is the screen. If it blacks out on the monitor then it is the video component of the motherboard. In that case you would most like replace the motherboard.

Hope this helps!

Backlight working but Display still blank, what could it be?

If you connect an external monitor to the video port on your laptop, power up the monitor first and then boor up the laptop and the video information will automatically display on the external monitor. This will indicate the on-board video is functioning OK and the problem is the video connection to the LCD screen.
The video connector from the LCD screen may need reconnecting to the motherboard to restore video information on the LCD screen.

Screen is blank lights come on

Hook a external monitor to the video output usually on the back. If picture okay! the inverter board below the screen is defective, or the backlight behind the display has failed. But if both have the same symptom it is the Video Graphics Card that is the issue, normally built into the motherboard.

Hook a apare monitor to the video output usually on the back, if picture okay! the problem is the inverter board "below the LCD screen" or the backlight behind the LCD display. But if symptoms are the same, the video graphics card is the issue normally built into the motherboard.

I took my HP Pavilion dv7-1132nr on vacation with me and the monitor sporadically goes black. I thought it was in hibernation but I cannot get it to go on. I do a hard stop and after about six or seven...

This is most likely either an issue with the display itself or the cable that is inside the laptop chassis that connects the motherboard to the display. The cable can get pinched and unplugged by the screen being opened and closed (if it wasn't assembled properly). This can be about a $200 fix. If it is the display itself cutting out completely, it is typically over $350 to repair through HP. If there is a dark, washed out image that is barely visible, it means the backlight is going out and that is at least a $300 repair.

Screen is blank when powered up and i cant see anything on the screen


Connect an external monitor / display to your laptop to see if your laptop's display is faulty.

If faulty, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim rather than a slow degradation, the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

My s10e lenovo is on but there is no display please guide me what is the solution of it. all lights are on but display is totally blank

Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

The screen on my compaq armada is blank. i can

The display panel itself is probably fine, but its backlight isn't working. Without the backlight you can't see the display. There's a small circuit board called the inverter inside the display that provides power for the backlight.

It's pretty easy to replace the inverter. You need to take out whatever screws are holding the front half of the display to the back and remove the front. The inverter is at the bottom of the display, held in by a couple of screws. A couple of cables plug into it.

Here is a place that claims they have the inverter in stock for $7.39. That is one fantastic price! Get one of those and a set of miniature Phillips screwdrivers and you'll be able to fix this yourself.

Laptop LCD display problem

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.

IBM 770 screen blacks out sporadically

If you have an external monitor, try plugging up to that to see if it is an LCD screen issue or if it is a video card issue. If the monitor does not show the same symptons then it is the LCD screen. If it does then it is the video card. Usually the motherboard will need to be replaced if it is the video. If the screen, then it will need to be replaced.

Hope this helps!!
