How do I darken the colors coputer screen


Hi!

If you're looking to turn down the brightness on your display, there should be some brightness keys located along the top of your keyboard. Usually they have little pictures of the sun on them.

Try toggling those and see if that helps!

The color on my tv is turning green. It's not totally green but it's becoming green. No matter how I adjust the colors it remains the same with too much green. You can't see the true colors...


It is very common for the color of the lamp to change as it nears the end of it's life. Depending on the bulb itself you may see yellow, green, or blue shifts (I have even seen red/orange). This is due to the diminishing output of the bulb and while you can make some adjustment you will eventually hit the point of failure. The bulb could in fact last several more weeks or even months depending on your use and environment. It is probably a good time to start searching for a replacement now so you can replace it as soon as it dies or just replace it now if the color is too bad to be worthwhile.

It looks like the red is not converging on my Hitachi 60V500A LCD Rear Projection Television. I'm thinking that I need a new Lamp Engine. Does that seem correct?


Good Luck with this. We have complained about a darkening screen we were told to replace the lamp. We did so for $100. After the problem was only getting worse, they said it was because I did not purchase a "Hitachi" bulb. They stated they knew their's were more expensive ($300) but should solve the problem. Well, we didn't bite. It became clear that we no longer could see blues, pinks, yellow, and most browns. A call back to customer service stating these problems ended with us learning we needed to replace a color engine to the tune of $850-$1200. We have only had the tv for about 4 years. Needless to say we bought a new Samsung Plasma for a little more than the replacement part. Hitachi products, never again.

Samsung dlp hls6186w, picture has darkened, could it be the lamp or is it the colour wheel??... tv is making sounds...I thought it was the fan, the fan looks okay??? It also shuts down once and a while...


The lamp is the only thing that will cause the picture to go darker. According to the model you have the lamp part number is BP96-01472A. The noise you hear could possibly be the color wheel itself. The way to tell is when you turn off the TV the lamp stays on for about 10 seconds longer. Once the lamp shuts off if that noise goes away then it is a bad color wheel. Any noises past that would be a fan. Please take a moment to rate my answer. Thanks...

When playing a dvd the color randomly darkens and then brightens


If I had to guess I would say its the back light on the TV dying, pay close attention to if it is doing at other times and not just during DVD / Blue ray usage. If it is just during the DVD/ Blue ray usage then it could be either the Blueray drive, the video cable going bad, or the video card in the PS3 going bad.
See if your PS3 is still under warrenty if it turns out to be the PS3.

If this still doesn't help your problem, please leave additional comments and I'll see what I can do.

This is called a dark shading error. All the LCD consumer sets have some visible degree of this effect. Some will be a little less or more than others even from the same batch in the assembly run. This has to do with the optical design quality of how the back-plane lamps illuminate the screen. The design and assembly tollerance of this area is very critical.

Normally, LCD screens don't show their best picture in a darkened room. The very black regions of the picture content may look a little washed out. LCD screens are best watched in a room that is lit, but not very bright. You have to consider that there is a powerful set of lights behind the polarized panel of the LCD display, and there will always be some breakthrough of light.

If you want a TV that is more like a CRT in its characteristics a Plasma would have been a good choice. The trade-off with the Plasma is that it does not have the picture sharpness of the LCD. A Plasma set is best watched in a darkened room.

If you have an LCD computer monitor, take a look at it in a dark room with a black screen. You will most likely see the dark shading errors. Only the very expensive production studio type LCD monitors have less of this error than the consumer sets, and they are not absolutely perfect.
