Question about Televison & Video

My Sony FD Trinitron Wega has no red color on the screen. All the usual adjustments don't help. No other TV in the house is doing this. Is the picture tube dying? Is it worth fixing?

    Black and White.

    All plugged in.

  • patsystair Jul 24, 2009

    I don't understand what you are talking about regarding the schematics of the TV.

  • patsystair Jul 24, 2009

    All I have is the operating manual and it just shows the drawings and connections on the back of the TV. ARe you talking about the insides of the TV??

  • patsystair Jul 24, 2009

    That didn't come with my tv. Can I find it on -line?

    Yes, I'm talking about inside TV, schematics or repair manual.

    That means picture tube is fine and color processing section got problem. You need to have schematics of TV for troubleshooting.

    TV Model number is very very important to answer your question so intimate exact model number of your Sony TV.

  • Dan Todd May 11, 2010

    Go behind the TV and make SURE the cables are fully plugged in. I've seen more than once where one would get partially disconnected but still be in the jack.

Could be the picture tube but also a broken resistor / RGB IC on the picture tube panel.

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.

My Sony FD Trinitron WEGA KD-34XS955 flashes red on the screen and turns off. Why? How can I fix this?


Hi Anita,

The red flashes then get off, usually because there is problem with IC's on its D board ( power supply board) . There are two IC's there and need to replace one or both of them. Since quite hard to do IC's test, I suggest you to replace both of them.

My sony TV trinitron wega 42 inch picture is red. Is there any solution to remove the problem?


The problem with your TV trinitron wega is at the color adjustment section. It is located at the color board mounted at the back of the picture tube. There are variable resistors that represents the color pattern in the picture tube. Adjust the red color to low level to lower the red color.

Sony FD Trinitron Wega model KV-34BR800


Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.
