The Contrast and Brightness on tv appears to be dark.
I own a 36" toshiba 36AF41 standard tv and the problem I'm having is, just recently I've noticed the picture on my tv was quite dark. When I went to make the proper adjustments, there wasn't any change in the color or the brightness. I turned the color and brightness all the way to 100 and the picture appeared to be bright for the moment, but it seems dark again. What seems to be the problem here? Do I need to get the tv repaired or would this be a do it yourself fix?

Re: The Contrast and Brightness on tv appears to be dark.
If this is a CRT-based TV and it's been played most of the time, you may have a bad picture tube, especially if strong red colors bleed to the right. CRT's dim with use, unlike LCD or plasma. But it could also be trouble in the video circuits - none of this falls into the DIY category, unfortunately. High voltage involved, unless you're comfortable around it and want to try turning up the screen controls inside the TV. If you do, let me know - but "no response at all" from the external adjustments points to a more serious problem.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Please view my Tips & Tricks. I have a tutorial which will help you correct this problem. Your Screen Voltage is too low. You will need to take the back of the TV to fix this. It's not hard, just be careful... the TV must be powered on during the adjustment. I hope this was helpful, best wishes.
If this just happens while vcr is playing. Check the vcr. Did you happen to adjust its brightness and contrast settings. If things doesn't change. Then if this model is a crt type could be adjustment on its flyback transformer is needed tweaking slowly its screen knob or tweaking also its focus knob until you got it to the level of viewing it correctly.
But be aware, hazardous voltages inside it. Or let th technician set it for you, its a minor adjustment.
It really depends on what YOUR eyes are pleased with - if 50 looks good to you, that's where it should be. It seems like you might be afraid of messing up something - don't worry, you can't hurt the TV by adjusting the customer controls :-) You might try a little experimenting - kicking them up to 75 might give you a brighter and more pleasing picture. I've been a TV technician for years, and I generally like the brightness and contrast up almost to the maximum (I like a bright picture as opposed to a "warm" one), with the color and hue adjusted for an accurate reproduction of facial tones. But the bottom line is what YOU want - feel free to experiment, you can't hurt anything as long as you don't start taking out screws :-)
You can set these controls to your liking, though a lower brightness setting might increase the life of the screen. First, set the brightness and contrast to a level that is pleasing to the eyes, then adjust the color to look realistic - enough color without being disturbing. If faces area look greenish or purplish, then also adjust the tint (sometimes called Hue) until you get accurate flesh tone. Flesh tone is the best thing to adjust for; when you get good flesh tone, the rest of the picture will look great. ALWAYS make adjustments during a live news broadcast, which tends to have the most accurate balance of brightness, contrast, color level and hue. Note that commercials are all recorded in different studios with different settings, and will usually not look right - it's best to just live with this than to constantly readjust the TV. There are also DVD's available which walk you through proper TV adjustment.
you can bring more brightness by removing cover on your tv and then you will see ther 2 button ther in back of your tv one is FoCUs and other is G2 rotate the G2 button till you see more brightness on your screen put the cover back and that is if you dont know to do that go to one authorised service
