I have a magnavox big screen tv that was giving to me. i do not have the manuals with it. when i turn it on. the color is in three demension I cannot get it adjusted where they colors are all together.


hi,
first of all check the tint setting on your TV picture menu.
if not get the correct color then, your telivision is a dlp TV that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for counting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same.
ok

Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Black screen ecept for thin white line around all four side. Channel buton changes colors in various section of screen. On/ off button does not work


I found the solution on mine. To restate, I just saw a thin white border around a black screen. Pressing the channel up or down buttons changed the screen, in some kind of test mode to shades of gray, and red, green, and blue. I started finding a solution when I noticed when on one of the color screens, that the volume up or down buttons brought up a new menu for color intensity. Finally, I got back to the thin white border screen and pressed the arrow keys in the top half of the remote. Finally a TV screen and I pressed the enter key! Voila!

Sony Screen keeps Blinking


If the red LED blinks 5 times you have a AKB error. It is caused by the CRTs trying to balance the color, and failing. Its an annoying problem that happens when the CRTs get old. If its just beginning you can balance or slightly turn up the screen voltage to the CRTs to remove the problem, if its in the end stages, the CRTs may need to be replaced. This is however, very expensive. If you are daring and safe around high voltage, pop off the speaker grille, open the front panel up and find the focus block. Don't poke around! those big red wires have 30,000 volts running through them! The focus block is a black square box with six knobs on it. Three are labeled screen, three labeled focus. You will see each row labeled R, G, B for red green and blue. The writing is tiny. Mark all three screen knobs with a colored marker so you know where they started. Then turn each one up slightly. If you have a picture, put it to a black screen or blank input. Turn each knob up just unit you see the color over drive and turn it back down to black. You want to set it just below retrace to maintain black level but drive the CRT fully. Setting this is hard but may fix an AKB issue.
