Hi.

Problem is either inverter or backlight system. If some of the back light lamps are coming on, that probably means that the inverter is good. That is bad news, as back light is integrated with LCD panel and does not get sold separately. LCD panel is also expensive, and may not be worth repairing.

Below the inverter, part must be tested before replacement, as mentioned the problem could be the backlight system integrated with LCD panel:

Samsung SSB400HA20V Backlight Inverter The fault you are experiencing is not common, and may need a problematic repair. My advice is that best first action would be calling Samsung at the number listed on manual and asking them a quote on repair.

My camera over exposes everything - the shutter stays open for about 2-3 seconds. except when on video settings. No matter what I set it at nothing changes.


Looking down at the top of the camera, check the left knob. This is the exposure compensation dial. Adjust it to "0". If set one way or the other, it will make pictures darker or lighter. This comes in handy when the image has a lot of dark or bright areas - moving this dial will allow you to make the bright areas darker or the dark areas lighter when you camera's light meter is setting the exposure in a way you do not want.

If still having trouble, make sure the right knob (Mode) is not set to M or Manual. Switch it to Program or Auto and try taking a picture again. You might even want to set the outer knob (ISO) to AUTO as well to reduce the chances of an incorrect setting. If it now works as expected, but you want to shoot in M, you will need to learn how to use the meter to select the correct combination of aperture (f stop), shutter speed and ISO to obtain the desired results.

Oh, experiment with the exposure compensation knob when you have a chance, learn how it can help correct overly dark / bright scenes. Good luck!

I have a Dell Inspiron/E1505. when i turn on my computer i can barely see my screen and it says Presentation Mode is turned off. how do i turn it on?


To turn presentation mode on follow this:
  1. Open Dell Quick Set
  2. Click on Display Settings
  3. Check the box that says Activate Presentation Mode
But I don't think that will make your screen brighter, if its still dark then look for the function hot key to turn up the brightness on your screen. Its usually something like - hold the "fn" key and press the up arrow several times.

Pictures appear to be darker than original in print outs.


You can make several adjustments to improve your images such as lightening dark areas, changing the exposure, sharpening blurred edges, and changing the brightness and contrast.
  • Exposure adjusts the overall intensity of light in an image.
  • Adaptive Lighting improves only the dark areas in an image without affecting the bright areas.
  • Brightness adjusts the amount of light in colors ranging from light to dark.
  • Contrast adjusts the difference in brightness between light and dark areas of an image.
  • Sharpness helps define edges and the smoothness of texture in an image. Use this tool to make a blurred image appear more focused.
Adjusting the image Follow the steps below to make adjustments:
  1. Click the View tab and select the image you want to edit by either clicking the image, or by clicking the small box at the bottom left corner of the image. Figure 1: Select the image c00603524.gif
  2. Click the Edit tab and then click the Advanced tab.
  3. On the Advanced tools tab, click Adjust Image .
  4. Select an adjustment from the list on the left. Figure 2: Adjusting the brightness c00603525.gif
    • The Exposure adjustment is automatically applied when the Adjust Image tool opens. Eight variations of the image are displayed on the left. The current image is displayed in the center. Each image represents a different level of adjustment. When you move the pointer over any of the images on the left, a large version of the image is displayed. Use Preferences to turn this large image preview on or off and to set the timing for the display.
    • If you want to use a different adjustment tool, select Adaptive Lighting , Brightness , Contrast , or Sharpness from the list.
  5. Select one of the images on the left.
  6. Do one of the following:
    • Click Accept to accept all changes and exit from the Color Toolkit.
    • Click Cancel to discard all changes and exit from the Color Toolkit.
  7. If you have finished modifying the image, do one of the following to save your changes:
    • Click Save to overwrite the original image.
    • Click Save As to save the modified image with a different name.

Brightness keeps shifting on Samsung 46" 7 Series 750


I just purchased Samsung series 4 LCD TV yesterday. I had the same problem since my salesman was a kind of stupid. He set the 'Power save mode' to automatic. After fiddle with my TV for a while, I found the solution.
Just change the 'Power save mode' to off, low, normal or high. My LCD TV stopped shifting its brightness.

Dark picture (HELP)


Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
