    Hello,
    Thank you for the information. I am absolutely certain that the problem is the CCFL lamp. I know about the site www.lcdparts.net - I went there to order a replacement, but I need to know the specific details of the CCFL lamp, i.e. dimensions, type, etc. Without them I cannot make the order. Can you please send me these? Thanks immensely.

First thing is to check if the video card is OK.
Connect an external monitor to your laptop, if you get a clear image on this monitor then the video card in the laptop is OK.
A faulty backlight could be caused by a defective inverter that supplies high voltage to the CCFL lamp or a faulty CCFL lamp. Most likely a faulty CCFL lamp.

The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
Check out www.lcdparts.net for parts, repair service and DIY info.

    The length of the CCFL lamp is measured from the left hand edge to the right hand edge of the screen.

    You can go to LCD Parts page - Selecting CCFL page where you can also select the CCFL lamp by the laptop manufacturer and model.

Scren black.. Very faint outline of the programing can be seen


Hello
The backlight of your TV is OFF. The main reason for this fault is with a defective backligh inverter transformer fitted inside the TV. This inverter supplies sufficant voltage to the back ligh CCFL lamps, and in turn adjust the brightness of your TV. There are mainly two resons for this fault. Either the backlight inverter transformer has damaged or it drive circuit is damaged. You have to check and find the reason. It is dangerous to work with this section, as this backligh inverter generate very high voltage. If you are not familier with this type of repair, get it repaired by any experienced technician. OK.

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


Hello.

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.

No picture Just Sound


Hi
There are different possibilities in your case¸but what happened to me ...
The LCD Backligh is out , I mean the bulbs or neons of the screen BACKLIGH, you have to check either the lights itself or the driver circuit which supply the HV to operate it, usually its a separate small long PCB beside the TV main board .
You can try this trick , Keep all lights off in the room and bring a table lamp, preferred a white neon one and face it lighted on the top of the screen with the TV on , try watch a very dark but exact picture with the sound you are hearing. This is a way to be sure that it is LCD backlights problem when using an external light to illuminate the screen .
It worked for me ,Good luck
