Vertical lines showing up after being on for awhile


Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

Dull laptop screen back light


You may have a faulty CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, 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 or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Goodmans gtvl32w27hdf - screen is flickering and picture is darker than it should, but sound is fine. Have tried turning off and on. doesn't matter what channnel you're on and its the same for video so i...


It is most likely the screen backlight. LCD TVs have thin fluorescent lamps and a part called an inverter board which is a transformer similar to a light ballast.

Inverters are typically a $50-100 part and are trivial for any technician to replace. The backlight lamps themselves tend to go pinkish when near the end-of-life, and are a low-cost part, but it requires a lot of work to change the lamps.

IF the LCD display itself is good, then the screen image should remain perfect and undistorted...if the backlight fails altogether, you should be able to see the image by shining a bright flashlight directly on the screen (only as a test, not as a long term solution, obviously :) )

Flickering and screen dark


sounds like the lamp on one side of the monitor is going out.

It is repairable depending on how tech savy you are.
