Re: Color

It needs repaired. I can think of many different possibilities causing the problem: 1. Shorted video luminance driver transistor. Should be under $200 total repair if you take set in. 2. Shorted green kine bias transistor. $200 3. Failed jungle ic. $250 4. Shorted green gun in the picture tube. More than you paid for tv set... Rca picture tubes commonly run 25% more than the tv set did new!!!!!!!

Why do i have a green screen after i turn the screen adjustment screw?


since every display color monitors are only work with 3 primary color which are red, blue and yellow. You could also search it that by mixing these colors, you could get any color your want. Thats how color monitors work. Now in case of green color, it creates by mixing blue and yellow. When you are turning the screen adjustment screw, the red color plug will become lose, makes it appear green.
I hope your got the reason.

I have a sony kp-53n77 rear projection tv i cleaned the lenses but i still have alittle to much red how can i clean up the color


Older projection set:

Not knowing exactly what it looks like I suggest two things: first in the menu look for convergence to see if it is off adjustment wise--it can be adjusted in customer mode to see if that helps.

Also either turn color all the way off (Black and white) to see what color the screen is with no color--if somewhat red you will need to turn the red screen control down--I can tell you where and how.

If screen is too red, red will be the prominent background color with color off or on.

Another easy way to LOOK is go to an unused video input---should only see "Input 1" for example in green and rest of screen should be black and not red to any degree.

Let me know with a comment here what you find.

Red blue and green projector lamps not lineing up on screen


Cover any two of the lamps first and focus the uncovered one. Then be sure to adjust the electrical focus of the same color. Then move to the next one and so forth. At its best you will have to decide which color is off convergence, and that one will be moved a bit out of focus, in this case the optical focus or electrical, tweak and you shall receive. Good Luck...

TV KOLIN 21"


hello.... do you have any speakers near your television? what color is the circle your talking about? Do the green,pink colors are scattered all over the screen and specially on the corners?
If you have or had speakers near your tv? then do this try to get a magnet.a magnet on a speaker would do.what you have to do is to place the magnet near the screen of the tv approx. above the green,pink color (turn it on first).you will notice the that the color will react with the magnet try to pull it on the side you will notice that the green,pink color is moving on the same direction do it until its gone.NOTE make sure youll not scratch the screen ok.email me what happened. jaredreyesbalderama@yahoo.com GOODLUCK

Samsung dlp color issue


I just had a service tech out and replaced the color wheel. now i have the same issue with the color...the people all look blue. He told me that now the the digital board is bad. It's the board were all of the connections go. I'm not convinced, as I remember reading something about color settings needing to be adjusted after color wheel replacement.

Color sudden change


Good day.
Your unit is still worth. It may be a caused of loose contacts along the circuitry. It can be remedied by resoldering the terminals particularly the chroma section and the crt circuit.

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):

 

1) turn color and tint fully counter clockwise until you have a black and white picture.

 

2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray

 

3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.

 

4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.

 

5) adjust the focus screen and control grids to match the ones on the schematic diagram

 

6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.

 

This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.

 

However if you do not have a background in electronics please take the TV to a shop for repairs.

 

I hope this helps,

Thank you,
