    I think I have a lot of dead pixels
    Theres this interference and i guess tiny square dots from top to bottom for a 2-3 cm diameter. Its like a television screen when there is interference. Am I looking at dead pixels here, or is it something else? Is this normal for Toshiba to have dead pixels? Will taking it to a toshiba depot make stuff even worse (ie: will something else go wrong?) Any comments or opinions would be great!
    Thank you

    I'd try out Dead Pixel Buddy (search it on google) and test your screen out with that. DPB will give you the best way to evaluate dead pixels.

    This is just a portion of my screen. This is the size of the ....blob haha. Is it dead pixels...or something else.? There is more at the bottom, which is not on the picture.

    Whoa!! What happened to that screen :eek: ?? Yep, those definately look like dead pixels and definately warrant and exchange. I'd try restarting your computer as well as changing the background/resolution to see if it isn't a software glitch.

    I already tried reinstalling Windows (Toshiba tech advice) haha The blob on the pic is just 2-3 cm. It looks really blown up in the pic. The green background is from DPB. Why do like lines keep appearing and disappearing eradically? I though dead pixels were dots.

    There are dots, but on top of that there are the lines moving

    Hmm...
    That's really odd....Dead Pixels usually stay in one place and don't change color or are unactive or dark (hence the word "Dead"). However, as you described them as "moving" and "changing" I would suspect this to be some sort of software anomaly. However as you said you've already re-installed Windows , I really don't know what to tell you. Try flashing the BIOS, and if that doesn't work, I'd first re-install Windows again, then exchange it if it still doesn't work.

    I guess I could exaplain it as saying that there are these tiny dots, and then in the front there are these lines that appear and disappear. I tried flashing the bios, but it wouldnt let me because it is already updated

    That really confuses me :confused: Try reverting back to the old BIOS version, see if that helps any. If that doesn't work, I'd exhange/return the laptop for another one.

    Go into the Cotrol Pannel - Then click on System - Then click on the Tab "Hardware" - Then Device Manager - Scroll down until you see "System Devices" and open it - Then click on "Microsoft System Management BIOS driver" - Click on the "Driver" tab - Then click on "Roll Back Driver"

    Try rolling the driver back first and see if this has any effect. If nothing happens, re-update the driver again and see if anything happens then. If this doesn't work, I think you should take your laptop in for an exchange - something is clearly wrong with it.

    Well, if you're out of you're exchange period, I'd get it serviced under Toshiba's Warranty. If that doesn't work, I'd want a replacement from them.

    It should be covered by the warranty. They'll be crazy if they won't accept your notebook.

    Notebook is for ready for servicing, that is for sure. It is not like servicing a car! They must fix it or give you another! Don't worry to much about that.


    BTW xAMDvsIntelx wrote:

    I think you can't revert flashed BIOS by just reverting the System driver called "Microsoft System Management BIOS driver", or am I missing something? I think we are talking about two completely different things here. One thing is FLASHING BIOS (main or GPU) - changing the contents of an eeprom chip. The other is REVERTING windows driver (no connection with the contents of BIOS chip at all). I think Jun85 tried to flash BIOS to a newer version, succeeded, saw that didn't help, and then tried to put back the old version that again is not usually possible (at least with few I tried). So I write this in order to clear things up. If you think that maybe reverting this driver might help flashing the older BIOS version, that is another story, but I doubt it.

    Well if you're having problems before the first 6-months, the yes, I'd get an extended warranty. I'd go for the 2-year extended or the 3-year extended.

    I don't think these are dead pixels at all. Dead pixels are measured in "sub-mm" size, not in "cm". Since you already reinstalled Window and did not help. I will say it is a problem on your video card/video chip. Looks like the video card/chip can not really produce a balanced video with correct refresh rate. I suggest bring it back for service.

    Well, that's not completely true - there are pixels that are "half-dead", meaning that they while they are defective, they can still display a certain range of colors. I'd try trying running through the color spectrum on Dead Pixel Buddy, ptonello. I don't believe this is a VCard problem, as the whole screen would have problems as opposed to just some of the pixels.

    Try checking the colour setting in the driver (if you can find it). On my ati and GMA900 I can set Red, Green and Blue intensity, contrast and brightness. Maybe something went wrong there? Did you try reinstalling driver? I wouldn't bet on it, but it may help. Did you ever leave your notebook on direct sunlight or extreme cold? I saw some LCD that were partially showing similar effect because of exposing to high temperaures.

    From the looks of things, I dont think its dead pixels....The lines and blotches is coming from software or hardware conflicts. Half dead pixels can be a good guess but bad software and/or bad integrated video chip can be another suggestion. Try to warrantee and see whats the result....if they say nothing is wrong and give you the problem list hence software error or something else. My advice is same as the other guys, take the extended warranty if you still have the option. (just incase its a lemon)
