SOURCE: LCD Display flickers,then goes dark on bootup

Sounds like your display inverter has gone bad. You should be able to find an inverter for this model or if the computer is still under warranty I would find an authorized repair center for this brand of computer.

SOURCE: Have 3- 13 watt mini spiral bulbs on fixture. When

-Replace the compact florescent bulbs with regular incandescent bulbs and see if problem continues.
-Lighting controls are made for different kinds of bulbs.
-Your package should say what the watt rating and type of bulb.

According to the PR180 manual:
-I am looking at the Leviton PR180 occupancy sensor manual, and the PR180 sell-sheet, and these documents say for incandescent and fluorescent (rapid-start magnetic ballast only).
-Compact fluorescent are supposed to have a magnetic ballast.
-The manual does not specifically say it works with 'compact fluorescent'
-The manual does not say there is a minimum amount of wattage either. Some controls will not work correctly if the overall wattage is low. Your overall wattage is 39watts.

Read the product package (if this is a new installation and you have the package)
Try the incandescent bulbs.
If the PR180 is not your product, add a comment with product number and I'll look for information

When I turn on my Samsung LNT4661 LCD the screen flickers and goes black but I still have sound. Looking in rear upper corner I can see the floresent light comes on and then flicker and then a buzzing...


The problem is related with the lamp and the t-con board of the television. Once they are about to develop a fault, that is when the screen will begin to develop some kind of flickering, sometimes, the screen can actually fade out in brightness and sometimes, the television can start tripping off on its own or you will have no picture but still have sound.

There are two components that can be responsible for this, but i believe it is the lamp of the television. The components are the t-con board of the television and the lamp.

Then if it is the t-con board the screen will go blank and the sound will still be okay. But if it is the lamp, the screen will not come on and the sound also will not come on either, but sometime it might act funny and the sound will come on but the screen will not come on.

Therefore, i strongly will advice you first check the t-con board, it is at the lower middle of the main board, then you check the lamp to know which is faulty. Once you know which is faulty out of the two, all you need to do is to have it replaced and the television will be in good condition once again.

If you are not familiar with such electrical job, i will advice you seek assistance from a friend who is electrically fit to do so, as the job requires a high level of technicality and electrical scopes.

Hope this was helpful to you.

How do i fix my web camera to not turn me purple when i web chat?

You'll need to get an desk lamp of some sort to light your face.
What is happening is that your face is being lit by your computer monitor, which will give it a purple cast to it.
Find a nice, bright soft-white desk lamp to place to the side of your computer screen and that should be enough to prevent the purple face.
