My 27" Sony Trinitron XBR's color became mixed, i.e., the picture is clear, however, the color has changed. People's faces are a light green. There's more purple. The only control I have is with the remote. What do you think is the problem & how can it be repaired? Cost?

A friend of mine had a similar problem and a repairman simply replaced a chip. Cost = approx. $70.00

Greg0915,

It sounds like since you still have sound on this set, that you could have a problem in the vertical sweep circuit, or in the video processor circuit of the TV set. I have also seen the High Voltage block cause a no picture condition. Also there is a small resistor off of the flyback transformer that will heat up and you will get a bad solder connection or the resistor will go bad. This resistor goes to the filiment of the piture tube(s). Does the Light flash in any order or random? What is the model number?

Nate Dog, what does the picture look like when you lower or turn off the color all the way. If the screen or when you watch a B&W movie or show on the TV set, and the picture Without the color looks purpleish, or a differant color, and not B&W, Most likly there is a problem with the picture tube, the auto kine bias circuit, or in the RGB driver circuits.

Larry Dillon: When I turned the color off, the picture on the screen is black and white... no other colors, no hue, no tint, just black and white. The picture is still clear.

It is probably a fault in the color processor circuit since the set has a good B&W picture. this could be a almost anything in that circuit .. Whats the complete model number? And chassis number?

Larry Dillon: Thank you for your response. The Model No.: KV-27XBR50, Serial No.: 7000B71, Manufactured: May 1990. I couldn't find a chassis number. What are we looking at as far as a color processor circuit? Again, thank you for your response.
