SOURCE: westinghouse LCD TV - broad vertical green and blue lines

try to go to the factory reset and see if that helps. If not, you can then check your connection. if you use component (red, green and blue for video and red and white for audio), make sure all the color matches when you plug it in. if everything have been checked then you need to replace the main board and it should correct the problem.

SOURCE: the colours on my tv have gone pink and green

Either your picture tube has gone bad or the transistor or IC on the crt board, on the picture tube, that feeds the blue gun has gone bad. You would have to test the transistor to see if its shorted or open with a multi-meter, or check the voltages to and out of it. The voltages are around 200v and dangerous if touched, best left to a proffessional. If its the transistor/IC it would be a cheap and easy fix by a repair shop, if its the tube, you may want to go tv shopping.

Hello, Sounds like an LVDS Cable or T-con Board.
Usually this will slowly get worse until it is repaired. It is caused by a failing T-con (Control) Board or connecting cable. T-Con Will Need replacement. This picture show's more extreme T-con board failures

HOW DO I FIX THE DISPLAY OF JVC TV? IT SHOWS PICTURE BUT THE COLOUR IS BAD. I HAVE DONE SEVERAL COLOUR SETTINGS WITH NO RESULT, DURING THE ADJUSTMENT, THE PICTURE CAN TURN TO SEPIA GREEN, SEPIA BLUE E


This sounds like a bad cable or connection. Swap out the cable with a known working one and see if that helps. Next, wiggle the cable nearest to where it connects to each device and see if that recreates the issue. If so, your cable either has bad ends or your device has bad ports/connectors.

How do I hook up my dvd/vcr to the tv


On the back of the cinavision you have two groups of sockets. The yellow socket under Video out is picture. Red and white is sound. Connect them to the TV's yellow red white sockets marked Video In 1. This connection will give you picture and sound from either the VCR or the DVD deck.

There's a better picture quality available for DVDs only from the Component video out sockets (green red blue). Next to them is another set of audio sockets (red white). Connect all five sockets to the TV's input number 2. The colours match up. The picture from Component will be clearer and sharper.

On your Sharp TV remote, select Video 1 to watch VCR, and Video 2 to watch DVDs.

No green and yellow colour


Hello
If you see the picture in yellow colour, means that there is no blue colour output from the video drive section in your tv, Yello is the mixtrure colour of red and green. Green is actualy there. blue colour is absent.
To detect this fault, you must open your tv. Just look in to the video output section, can be located at the picture tube base card, which is plughed into it diretly. See for any loose soldering points there. Check whether transisotors are used for red, green and blue output stages, or an Ic or three seperate Ics are used for this purpose. Anyway, blue catode of your picture tube pin gets a hig voltage, and so the blue emission is absent. You just check the voltages at red,gree and blue catodes, at the respective picture tube pins, which can be taken at picture tube base card. All of these three pin voltages must be somewhat equal to each other. In your case, no voltage at blue cathode will be higher that the other two. Check for the reason. It may be due to an open video output transistor [blue], or an Ic, of one Ic if used for the three colour outputs. Check and replace the same, will rectify your problem. Ok
If you have andy difficulty, get it to me through Fixya. Ok

ShubhangiWe try to connect CD player with Samsung LCD TV. CD Player is having Three Component Yellow, Red,White. It dont have Blue and green components.What to do ???


Hi, Component input connectors use the colour convention
Green = Y (luminance signal)
Red = Pr or Cr (Red colour difference signal)
Blue = Pb or Cb (Blue colour diffrence signal)

Composite input connectors use the colour convention
Yellow = CVBS (composite video, blanking, sync)
Red = Audio Right
White = Audio Left

for compatibility both units will need to have matching colours. note the component inputs do not have audio and as such will also have a set of red & white connectors for use with the audio signals too ( rule of thumb Component = 5 connectors, composite=3 connectors)

RCA F31317 lost blue in picture.


this symptom is characterised by the loss of one or two primary colours. this symptom can be classified into three cases: 1) loss of red colour, 2) loss of colour blue,3) loss of green color. this symptom may be caused by a trouble in the colour demodulator, in the color amplifier or in the colour subtraction amplifier circuit. in your case loss of blue colour. this is a very complicated problem that you need some special test equipment like oscilloscope and color pattern generator in order to trace the signal. tune the receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the chroma signal. observe the signal process with an oscilloscope. if the color signal is not present use a VOM to locate the defective component in any of the above circuits. check the transistors and the resistors in the collector circuit. good luck!
