light, bright display

When I turn on my computer, the monitor and the screen to look right. the screen is bright. However, recently, when I turn on my computer, the monitor is brilliant as usual, but turns off after about 10 seconds. Now my screen looks dim. Even when I change the contrast / brightness of my screen, it seems still very badly. How can I solve this problem and make it back to normal?

  • How to create uniform lighting (Fulbright) display 3d objects?

    I'm currently texturing an object with Photoshop, the problem is that when I try to use the eyedropper tool, it takes into account the brightness, the color is from light. So if I choose a color live and paint it on my object, it will be darker because there is not much light goes into it. Then when I use the Eyedropper, bright color, I took initially is now darker lighting. Top left is an object that has an equal brightness, while on the left is an object with the information about lighting.

  • Satellite P500-12F: brightness display problem

    Whenever I have Toshiba Support ring I always feel to do away with the same answer: 'use your recovery disks.

    My recent problem concerns the power options, there is a slider that allows to increase the brightness of your screen.

    My cursor is located in the Center, but if I try to move the slider to increase the brightness, it becomes darker instead, also if I select 'high performance' it becomes darker, even if I select 'eco', it becomes more clear.

    I think it's a hardware problem, while T.Support think it's a software problem and advise using my recovery

    discs, which as everyone knows is a problem a lot of your time.
    Someone had a similar problem?

    Hello

    The point why many users suggest using the recovery disk is simply; in this case you can easily find if it of software or hardware related issue.
    In many cases, some 3rd party installed tools or software that may affect the functionality and the recovery disc helps you eliminate it.

    However, what the use of the FN keys; FN + F6 decreases the brightness; FN + F7 increases the brightness?

  • The LCD screen no longer works and no housing or other lights are displayed since the last update.

    The LCD went blank since the last update from microsoft, probably for windows 8.

    I am running wireless through Windows 7, 64 bit.

    Everyone knows this?

    Looks like the LCD screen is out. It might be the screen, or possibly a link inside the printer.

    However, it seems that the printer is able to be used under the actions of the façade. We can print, scan, and even perform a scan-to-print copy.

    However, if you want to take advantage of the features of back cover then you will want to consider a different printer because it sounds like this is to have an electrical problem in the display. Think to call the HP Technical Support on the upgrade program to get a new unit reconditioned at a discounted rate.

  • Dark satellite A20 - retro-lighting on display

    Hi all

    on my Satellite A20, I've got a backlight is dark. A new inverter did not work.

    So I wanted to check the lid switch. But it seems that this laptop is not a conventional switch? Can someone tell me how the "open cover" function is performed on this system?

    Second part is that I wanted to check if the inverter on the GET proper nutrition. Does anyone have a pinout of the inverter? (It's a TAMURA HBL-0291)

    Thank you!

    Peter

    Hello

    I think that no one here can meet these technical issues such as the pinout of the inverter. In your case I would contact a technician for laptop in your country. Normally what you mean is described in the technical manual, but this is only available for ASP s, so a portable computer technician can give you more information.

    Alternative make sure that your BIOS version is up-to-date. You can download it on the Toshiba site.

    In addition you can also find a list of s SPAS where you can get professional help.

    Good luck! :)

  • Satellite Pro M70 - stopped screen lights

    Hello

    My Toshiba Satellite PRO M70 screen lights.
    I don't know why, but sometimes when the screen is broken and I put it up it turns on, but after a few seconds it stops.

    It started a few days without something strange in my pc like hitting or something like that.
    I tried to connect an external display and it works weell.

    Anyone know why it cant pass or how fix it?

    Hello

    The Fn keys work?
    You can increase the display button narrowly by using the FN + F7 combination?

    Please also check the energy saving profile.
    Maybe the display brightness is set to a lower value in the power saver profile.

    But if you will not find anything unusual in the settings of the software, so I guess that the brightness display problem is related to the failure of inverter FL.
    The FL inverter controls the brightness of the screen, and this part needs to be replaced.

  • Explanation of the brightness in Photoshop

    This question has been asked before, but he had no answer. The previous discussion is here:what is the definition of brightness in Photoshop?

    The term 'brightness' is often used in Photoshop for example brightness mix masks of mode and brightness.

    How the brightness is related to the Hue / Saturation / brightness (STL) color model used in the Photoshop color picker?

    East - related to the "lightness" in color Lab, or synonym for 'brightness', or what?

    Andy

    Edit: I found a post of 2008 Re: brightness/color mixing modes - what do really? which may have the answer. Clearly, I need to read more.

    In fact, re-read now, I think that I explained myself well enough in this other thread. Here's how it seems to me:

    Equal brightness the brightness L channel RGB lab is something different, the average of R, G and B, which does not take account of the intrinsic lightness of a color. He's averaging only numbers. And all of this makes perfect sense, given that Lab is used as the 'profile connection space' (or one of them anyway), in all color management operations, what Photoshop does all the time anyway. The point is - Lab numbers are always readily available and easily accessible. Lab is still there, under the covers.

    Applying a kind of calculation of RGB values for brightness is a dead-end road, this isn't how it works. HSB is derived from RGB, so there is no connection with the brightness.

    If you set the histogram on the 'Brightness' display with a RGB file, you get the same result as a reading of channels L in a histogram of laboratory. So clearly, they seem to be the same thing.

    The only person who could answer that with authority, is of course, Chris Cox, who wrote much of the code of the Photoshop color management. If all goes well, he sees this.

  • iPad 9.7 Pro a uneven lighting

    I noticed some uneven brightness on the left edge of the screen and wonder if others have the same problem. The scrolling on a white/site background is more noticeable.

    The best way I can describe it, it's like there's a small flashlight that is spread the light towards the center of the edge. A little more up to halfway in portrait mode, there is a pocket of light brighter than above and below. I already tried on a second iPad 9.7 Pro to see if I just got a bad device, but it seems to be both. Others see this?

    I ran a backlight bleeding test with a picture of a solid black and did not notice much on black light leak. But I've certainly noticed this inequality of scrolling on blank pages.

    Hello

    Have you checked the brightness display keys: FN + F6 and FN + F7?
    These key combinations will help reduce the increase in the brightness of the screen manually.

    But the brightness of the display change spontaneously when using the laptop or just after the restart again?
