unfortunately the coby company has gone out of business probably because they have produced an inferior product that has had many problems, many people are posting problems with these sets. it is better you just purchase a different brand of tv and leave this heartache causing product behind.
Hello there, Unfortunately, laptops are unable to directly change the contrast of the screen; however, if you download the ATI Catalyst Control Center, you will be able to do it via your ATI Mobility Radeon Graphicscard if you have one. Here is the link for CCC http://sites.amd.com/us/game/downloads/Pages/downloads.aspx Hope this helps! Thumbs up if it did!
There should be a setting for the dynamic contrast ratio(or backlite setting on some tvs). Turning the dynamic contrast ratio off should make the screen brighter. This is usually called the DCR setting, turn it to off.
If its starts out bright enough then rapidly goes to dark it may not be a matter of contrast. If it is the contrast hit the menu button and go into the video menu then select user defined as the setting select the contrast and adjust it to whatever specific setting you would like.
No matter how dark the contrast, if the room is dark you will be able to read it well enough to get to the settings -that is unless the display is burned out altogether
I have the same problem. I was able to temorarily fix the issue by taking the back cover off and blowing all of the dust out. But this only worked for two days. Now the problem is back. Did you fix the issue with your tv? Thanks.
*The brightness control setting determines how bright your picture will be.
*The contrast control sets the gain of the video circuit. This determines the difference between dark and light scenes. Low contrast settings make the picture "hazy". High contrast settings make the picture more distinction between dark and light scenes.
*The sharpness control determine the frequency
response of the video circiut. High sharpness settings give better resolution but also shows
more noise in your picture. Lower sharpness settings smoothe out the picture removing noise but also fine detail. It needs to be set for the best all around picture.
*Picture Enhancement is pre-set adjustments which give you
different picture qualities. You just select the one you like.
