This could be from a couple of reasons. It could be a transistor, or resistor on the neck board that controls the red gun on the tube if it is a tube tv. It could also be a weak red gun in the tube itself and may need rejuvenated. Or maybe it can also be a bad solder joint on the PCB that connects the yoke connector.

SOURCE: help,colour is wrong

Hi. The problem is either the degaus positor has failed which is an easy repair. Or have you recently placed hifi speakers or something with a strong magnet in side near your tv set.

SOURCE: Television colour

your problem is simple it is called colour patch. it is basically due to change in direction or you must have shifted or tilted. it might be due to magnetic effect like spkr,telephone near by it.just remove from that location. put of the set for 15 minutes &put it on .problem will get clear. ask tv tech. to degauss it by dega.coil.it hardly 1 second job. regards

SOURCE: Incorrect Tv colours

Hello Roloi,

This sounds like a problem with your yoke transformer. I would suggest having a qualified TV technician work on this problem, because it involves testing a component that could have dangerous current in it.

I hope this helps,

Thank you,

Directv can't connect my tv to he, what can I do, they say I need a green plug in in the back,with the red, yellow, white


What I believe they are trying to tell you is you need to hook up into a component input . It is a video input only and it has three jacks usually coloured red green and blue. Match up the colours with the receiver and you will get an HD picture. They way you currently have it hooked up is a composite connection with only the yellow being for picture. This cannot get you an HD picture. The red and white is for the sound. I don't know what you mean by he though.

Sounds like a loss of green--I am in USA and Scart term not used here but I am aware it began as internet slang for Component hookup--which does use a Green, Red, and Blue input cables---if that type then suspect no green from source or cable bad etc.

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

I have seen a problem in my tv is that there is no green colour display in crt. only two colour ( i.e. Red and Blue) or combination may be display. Pl. look into this matter , replay soon


Your problem may related to the green output or driver stage in your tv. Usually green calour is not tranmitted, only blue and red colour informatein are comming from transmitters. Green colour information is regenerated inside the tv by matrix network. If the matrix get damaged no green colour will be displayed. To check first; whether the TV colour picture tube's green gun is right or not. For that you must connect a resistor of value more than 470k 2W, to the green cathode of the picture tube base to earth. The connection should be done causiously, not for a long time. It is advised to do in intermittantly with just touches. When you touch the green cathode with the resistor with one side of it earthed, a green flash must come on the crt. You can do this test for red and blue too. If there is no green flash, or light picture tube may be faulty. It is a very rare case. You must check the volltages of the other two cathodes [red and blue]. The voltage at green cathode must be almost the same as other two.
Just check the green output transistor for open. If it is open, voltage at green cathode will be high. Also check the base voltge of the green output transistor. It should be around 2.5vDC. You can compare the base voltages of the other two transistors with green drive base voltage. If there is no base voltage, the fault should be in the matrix section. It is inside an Ic. Philips usually uses TDA series Ics in chroma section. Check the Ic pin voltages according to service manual and try to rectify the fault. It needs a technical knowledge and skill.

When using component cables(red, green, blue )


The series of the cable should go green red blue into the back. if you put the green in the red and the red into the green it give the TV a red base to go off of for the picture so everything is red. The reason the green cable won't is because it transmits a black and white picture which allows it a nice base to add the green and red to.

How to connect to TV


The Yellow/Red/White connectors are Composite+Audio
Yellow carries a composite signal and Red and White Carry left and right audio channels.

Red Green Blue Connectors are Component
Each coloured connector carries one 'component' of the picture

So yes, your extra set of red white yellow cables would be fine to use, just make sure you connect the same colors at each end red-red green-green blue-blue

However..... the red green blue only carry the video, you will still need to carry the Audio, this is usually done either by the red and white (L & R stereo) or your DVD may also have an optical or coaxial output to carry the sound. if there is no equivalent connector on the TV then you may be stuck swapping the red/white cables, usually though there would be 2 sets of red/white connectors one set to go with the yellow, one set to go with RGB.

Dvd playing blue picture


if it is hooked up with componant, thats the red blue green cables for video, and red white for audio, then you probabily eather dont have the red pluged all the way in, or you have the red audio, and red video---reversed, make sure to check them on the dvd player, and on the tv, if there correct, try using the composit input, that is the yellow red and white
