Re: Mitsubishi VS-6041- picture brightness not very...
The TV does have a screen control on each of the picture tubes ( there are 3 ) although I do suggest you have a qualified technician make the necessary adjustments as an improper adjustment can cause damage to the set. Should you deside to make these adjustments yourself, you'll need to remove the back ( or front in some sets) ( PRE-CAUTION, UNPLUG THE SET FROM THE WALL BEFORE PREFORMING ANY ADJUSTMENTS INSIDE THE SET ) The screen adjustments are located either on the bottom of each tube or in a group component located where the main High Voltage Wire ( large red wire from the black transformer on the deflection board ) is connected to. Look for a turn pot ( screw type adjustment ) that is marked SCREEN. When you locate it ( whether it be on each tube or in the group component ) turn it up only slightly and not to much, as excessive gain ( turning it up to much ) may cause the TV to shut down. When you have the proper brightness ( when it looks good to you ) close the set up and enjoy the renewed picture. Good luck and I do hope this has helped in some way

The proper way to set flat screen tv's is opposite of old school CRT tv. First, find a movie with dark scenes and pause on a really dark part. Now set brightness only high enough to see some detail - no more. then go to a really bright scene and set contrast just high enough for good brightness. You may need to go back and forth a few times to get good setting.
if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.
If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.
If the backlight lights up for a second it's probably fine - It lay odds on the display inverter in the screen. Actually finding parts for anything made by gateway may be difficult, however. They do not sell spare parts. Considering the size of the LCD i bet it would almost exceed the replacement cost of the screen to repair it
first turn your color all way off or down.try turning your contrast way down as far as it will go you should see a darker picture. now bring up the brightness to a point half way. bring the contrast up to see grays and whites and blacks...adjust brightness more if need be. now you should see a nice black and white picture. no bring your color up last ...not saturate but to your liking. if you stilll got problems i bet your video out transistor is shorted....meaning shop work.
If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
*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.
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.
