Dim screen Can faintly see log in screen but screen dark

I would say either the video cable has disconneted, causeing the led that lights the screen up to not function,, simpley take the bezel around the screen, take the small screws aroud the screen to slightley pull the screen away from the back top to see if the cable is, or has pulled loose...If now the screen is bad..

If you can see faint dim images on the screen, then your back light or power inverter has failed. They are not adjustable or repairable and must be replaced. If you can't see anything on the screen, the LCD has failed and must be replaced. Sometimes it's hard to see the dim images so use a flashlight to help determine if there is any image on the lcd.

My camera's backlight went dark. Occasionally it would work if I pressed just the right way, but it was basically toast.

Search ebay for an HDR-SR11 or HDR-SR12 flex cable similar to this one:

It's not impossible to replace, but it's definitely not for the faint of heart. Some offer a replacement service with it. I'm doing mine myself. Results to follow, maybe, if I remember to post following the repair.

It's not impossible to replace, but it's definitely not for the faint of heart. Some offer a replacement service with it. I did mine and it works excellently. An $8 cable and about an hour (plus a lot of pictures-as-you-go for reassembly) is all it takes.

common LCD dark.dim screen problem, u can google keywords get more information.
either LCD inverter failure or CCFL backlight lamp failure, ask for a pro get it fixed.
by using a flashlight could you see the image on the LCD?

Fn+F1 Decreases the display brightness. Fn+F2 Increases the display brightness.

It sounds like yout lcd inverter is blown. You can usually get a new one and replace it yourself. I would look on ebay. Its just a small computer chip that fits inside of the monitor housing.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, 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.

What you see on your screen are retrace lines, it can happen for various reasons. Jut lower the screen voltage by adjusting the knob specified as "screen" on the LOT, this will disappear.

If the brightness is dull even when connected to the mains, it maybe that your back lighting is faulty on the screen and you will need a qualified repairer, although it may be worth looking at a new notebook depending on the cost.
