SOURCE: LCD Screen is black

It could be either, if you can get another LCD screen (same make/model) you can swap to ckeck it out.
You could check the inverter by touching its output and if you get a bit of an electrical shock then you know the inverter is working or check it with a multimeter if you don't like electric shocks.

Hello,

It sounds like you just have a bad backlight power supply. Go to our web site at: www.ccl-la.com We have repair guides for many models of LCD monitors and the 204B guide should also work for your unit.

I hope this helps, If so please rate our solution.

Follow the instructions below and it will work.

Disconnect the Camera from the USB port and reinstall the CD or Downloaded software program.

When the program asks you to connect the camera to the USB port, do so and it should work.

Then to use it on the Web, do this.
Web Camera’s have to be setup on the program they are to be used with. Just installing the
camera on your computer does not set it up to broadcast on messengers or Skype.

Each program has Options that have to be setup in order for the Audio and Video to function
properly.


A. Skype Setup:

After downloading and installing Skype (http://www.skype.com/intl/en-gb/download/skype/windows/beta/downloading/) set it up as follows:

1. Go to Tools, then Options, and click on Audio Settings and set the Microphone and
Speakers to the computer Audio Card.
2. Then click on the Video Settings.
3. The camera if Installed Properly will come up and show a video picture.
4. Then, on the bottom of the page click on Save.

The camera and audio should function properly. Your friends and Family will now be able to
see and her to you.

B. Yahoo Setup:

After downloading and installing Yahoo Messenger

(http://www.soft32.com/download_30.html )

set it up as follows:

1. Go to Messenger at the top left and click on it.
2. Next go down to Preferences and click on it.
3. Next Calling and Devices on the right and set the Microphone and Speakers to the
computer Audio Card.
4. Next go to the Test Audio section and (in blue writing) click on “Open the call
setup assistant” and follow the instructions on the left window.

C. Windows Live Messenger:

1. After you start Windows Live Messenger, expand the view by clicking on the square on
top left next to the red X.
2. Then on the Windows Live messenger window on the right side, click on “ “Show Menus.”
And then click on “Show the Menu Bar”.
3. Next go to the Menu Bar on right side, click on “ “Action.”
4. Go to “TOOLS” and click “Audio and Video Setting” and follow the instructions.
NOTE: Your audio and video should work. Enjoy.

When done both the Audio and Video will function properly so you can chat and see family or
friends you are connected to.

D. AIM (AOL) Messenger

1. On the VIM sign-in window click on Edit.
2. Then click on Settings Enhanced IM.
3. Next click on Enhanced IM.
4. Then click on Audio Video.
5. The Audio and Video portion has drop downs so you can select the proper audio card and
video camera installed in you computer.
The Audi Video drop downs are
Microphone
Speaker
Camera

Adjust Your Audio and Video Settings:
In order to adjust your audio and video settings, please follow the steps given below:
1. Click the Audio and Video Settings button directly below the My Buddy or My Camera window.
If you are currently participating in an AOL Live Video IM session, a message will display:
You must disconnect the current AOL Live Video IM conversation before running setup. Would you
like to disconnect now? Click the Yes button.
2. The Audio and Video Tuning Wizard will appear to help you verify that your camera, speakers
and microphone are working properly. Follow the on-screen prompts.
Notes:
· The first time you use AOL Live Video IM, a message will display: Would you like to
first check your audio and video settings? Click the Yes button. The Audio and Video Tuning
Wizard will appear to help you verify that your camera, speakers and microphone are working
properly. Follow the on-screen prompts.
· images in AOL Live Video IM may appear reversed, or as a mirror image (text may
appear backwards) when you look at your own camera feed or at the picture-in-picture (PIP) display.
After making the settings your ready for a chat and video talk with your Family and Friends.

After you get your camera installed properly, DO NOT unplug it from the USB port as it will
cause the drivers to be corrupt and render the camera unusable till reinstalled it properly.
Hope this helps. Bud

SOURCE: Vizio vw47lfhdtv10a, screen went black,still have audio and with a flashlight I can see images. ages.

If the picture is there but dark that means that your backlight has failed. Based on the age, this set likely uses a Cold Cathode for the backlight. The driver boards for these do fail over time and unless the tubes themselves have failed, likley a new backlight driver board will fix the problem. Check Ebay as a good source for parts.

You need to perform the flashlight test. Turn off the lights in the room, turn the TV on, take a bright flashlight and shine it on the screen. Do you see the faint image on the screen?? You could have a defective backlight inverter, defective power supply, or a main board issue. You set will require diagnosis to determine.
