After replacing screen there is a grayish look during light hours


you replaced the inside LCD screen?
i guess there is a full story here, but...?????
light hours,?
you mean with windows open and the screen goes gray?

some monitors and tv's do that, now. called GREEN MODE.
turn it off. My stupid TV (LG) goes gray with a reading lamp on.
silly to the extreme that. Im sure yours is not with a room light sensor, but do RTM.
as you know , the screen is black lighted.
and old screens (2005 it is) do get gray and other effects.
my old view sonic, (now on server duty, off mostly)
has dim and yellow back lamps.and the LCD has age effects.
this is all 100% normal for 8 years, full time service,
in fact lucky it works at all. truth being.

elaborate what you see better may be we can hone in on the reasons. and the what you touched inside.

Cannot get lcd screen to work-it's white seems the graphic flex cord is lose or bad


Hook a spare monitor to the video output to ensure there is no problem with the video card, if okay! the lcd display in the laptop is the issue. If the flex cord is loose reseat it back into the motherboard plugin it should be good and tight to work properly.

My question: My HP DV5000 is not displaying on the screen and it worked well on external monitor


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.

Unable to see the screen but it is playing the songs, don't know what is the problem. is it battery or LCD. no body is accepting to repair, please let me know the service centre names and contact details....


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.

Screen doesn't work, when it does turn on it fades and I can't see it? Might be screen inverter? or lamp blown?

Toshiba M300 screen turns white blank.


White screen means that your lamp (back light) is working absolutely fine, but you could have a loose connection for the data ribbon cable, which sends the images to the monitor.
Carefully open laptop to reach its lcd, there must be ribbon cable which looks like this: mrc-0069.gif
It is very sensitive so be very careful with that, very gently remove this from the chip and reconnect it.
Hope this helps, Please feel free to ask me any further.

LG Netbook x110. The screen doesnt work


You could have a faulty inverter or a CCFL lamp, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. 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.

LG L1717S has no light


Hi, this is a common problem. One thing you want to observe is that the screen works, what's going on is that the screen LCD illumination doesn't work while the screen display is active. LCD's have screen lamps behind the screen, they are often called CCFL, (Cold Cathode Flouroscent Lamps). The inverter board in the monitor supplies High Voltage power to the lampls, so the colored wires should lead you to the lamps. This is the problem causing the screen to dark. You can research the model lamp type for an accurate replacement. Usually there are 4 or 6 lamps in LCD Monitors.
