Question about PC Laptops

1 Answer

Laptop screen Hi. When I turn on my laptop, the screen has a red tint to it. It flashes a couple times and goes black. I have connected it to a different monitor so I do know that the computer is ok and it is a screen problem. How do I know if it is a led bulb or some other problem?

    My screen went black so I removed the cover and detected that the video card has a little grey disk with copper wires wound around it had fallen off. I think that this might be my problem. I can't find one anywhere. Help

If you are comfortable with removing the lcd bevel from your laptop, you can check to see if it is the flex cable itself. Above the keyboard between the f1-f12 keys and the actual LCD screen itself is a small plastic strip that covers the LCD flex cable, as well as often contains various case screws that keep the unit together.

If you are careful, it should be mildly easy to snap out the small plastic anchoring hooks from the sides and center of the strip and remove it. Underneath that strip you will find a somewhat thick cable that looks like it is wrapped in micro-chain link tape (it's actually electromagnetic shielding tape). Trace the cable to where it connects to the computer near the keyboard, gently detach the socket, and re-attach it to ensure that it is properly connected. This is not something you should have to do, but if you are troubleshooting for the cause of the red lines on your screen, this is the most probable cause.)

The cable, the connection, or the on-board video card itself could all be culprits as to why you are experiencing distortion. My secondary recommendation if you do not feel inclined to open your laptop yourself, would be to take it into your local Best Buy and have a geeksquad technician check your unit to make sure your drivers are properly installed and it is not a software issue. Also, if you have a warranty that covers the unit for repairs, it would be convinient because you would already be at the store.

Hope that helps.

Laptop LCD/Display Problem, Green and Pink Tints???


Their are a couple things that could be causing this, My first thought is that the screen its self is damage. A LCD screen is composed of millions of tiny pixels so when some fails others will still work.
That other thought is that the GPU or video device on the laptop could be failing and creating video problems. Have you tried closing the laptop and opening it agian, this would help rule out a bad cable connection.

The screen is black and the power light is flashing not constant and I don't think the hard drive is turning


If the screen remains black and does not show the BIOS window when powering up, coupled with the lack of hard drive power, then it sounds like you have a motherboard failure.

If your fans also do not come up, then that will confirm it.

Monitor


You could have a faulty inverter, 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.

It's not working!


It seems to be a software failure. Try using your recovery CD to sort it out. If it continuous then i would recommend a clean install if there's nothing that important on your laptop.
