    Laptop Screen Problems

    I have an old Dell Laptop Inspiron B130. Been a pretty good machine for me for a number of years. However the screen has crapped out on me this weekend without warning. I have it hooked to an external monitor right now so I can use it. When I switch between the screen only and display on both and then just the external monitor, each time it pops up like it wants to show up on the regular screen but dies in less than 1/2 a second. Then every once in a while when I open the lid, the screen comes on and stays on as long as the lid doesn't move. Any one have any thoughts? I'm assuming that the fix is to throw it away and buy a new one or use the external monitor. Appreciate any help.

    Re: Laptop Screen Problems

    Can you make out anything on the screen when it's not working - is it the backlight that is out?

    Re: Laptop Screen Problems

    I am not sure on your particular model of laptop, but I have seen on other laptops where the lcd screen does go out. Usually a screen can be replaced but unless it is still under warranty, the cost of a new laptop may not be all that much more money.

    Re: Laptop Screen Problems

    I would guess it is the back light on it. It is likely that you have a broken wire on the wiring harness that connects everything together.
    If it is the backlight you will still be able to see a image on the screen it will just be very dark.

    If you can find one the harness should cost around $100. And it will likely be around $100-$200 for someone to fix it. In other words it is not worth the money to spend on it.

    It could be a worn ribbon cable. Over time the outer coating can wear off of the cable. When the exposed cable touches the metalic back of your screen, it shorts out. A symptom of this is when you can move the screen back and forth and can get it to sporatically work as the cable will sometimes short out.

    Here is a link explaining how to take the display apart if you feel like exploring.

    Re: Laptop Screen Problems

    I support a lot of Dell laptops, and on several Latitudes, (assume inspirons must be similar,) at times, the connector to the system board, can come slightly loose, if you remove the keyboard, you can try reseating the lcd panel connection, sometimes it works, sometimes it doesn't.

    Re: Laptop Screen Problems

    Thanks for the ideas. We don't carry it around much. The battery has been completely dead for several years. I will think about breaking out the old EE skills and seeing what I can do with the ribbon or the connector to the system board, all of which are long outside my ability despite the degree on my wall. (after I back everything up of course). If I can't I'll probably just buy a cheap flat screen, so I can use the one that it's hooked to now to watch tv. Or I can just use my rebate I got last night from the Feds to buy a new one.
