Do not know whether the Tube is going

Our Tv's colours all seem wrong we have tried to set them in but we get a lot of green. The faces of the people are all green. Then there are lots of shade of pink and purple we could not even see which rugby team was playing. Any advise would be appreciated .

Picture is greenish hue and cannot be changed from menu bar


The greenish hue cannot be adjusted from the menu. One has to do it from inside.First confirm by turning the color settings to zero using the remote. You should get a clean black and white image with no traces of any color ( inc: green ). If your TV is greenish , the green drive on the base of the picture tube has to be trimmed.
All you need is a screwdriver. There are dangerous voltages inside a TV, some as high as 27,000 volts !!!. Where the color adjustment has to be done there are voltages as high as 110 volts and 8000 volts.If you still want to make the adjustments yourself revert back for instructions

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

Faces on picture are mostly green tinge


Hi. this problem could be caused by a few things. firstly to identify electronic failure or wear, I need to know the approximate age of the tv, whether the problem happened overnight or over weeks/months, whether any other colours are affected and whether the problem is all over the screen or in the middle of the picture

Hitachi C21 model.The colours on screen have got scrambled.


It sounds like something has left a strong magnetic field on the face of the picture tube, and that's causing the colour distortion. The electron beams from the tube's colour guns are hitting the wrong spots on the face. There is a degaussing circuit in the TV that tries to neutralise such fields every time the set turns on. Sometimes electrical equipment (particularly motorised appliances like a vacuum sweeper) operating too close to the TV can leave a field too strong for the degaussing circuit to cope with. Or a failed part in the circuit may have made it inoperative.

A hand-held degaussing coil can be used to remove the field. You can purchase one online, or call a TV service technician. It used to be a standard tool to carry.

Another possibility is that the tube has been damaged. There is a very thin metal mesh screen called the shadow mask behind the face of the tube. If this mask has been warped by a strong magnetic field or a mechanical shock (if the set was dropped, for instance), you will see the same colour distortion. In this case, however, there is no repair other than tube replacement. And that is likely to cost more than a new set with parts and labour.

The colour has gone wrong on my tv it show the the green and blue pigment but not the red. wil this be an expensive repair?


This problem could be as simple as poor solder connections on the board that sits on the back of the CRT to a defective driver transistor for the red gun to a bad picture tube. It is possible that this is an inexpensive repair (solder connection or defective transistor) or expensive (bad tube). If you can solder, try resoldering the CRT board connections and see if that resolves the problem. If not, then have a shop take a quick look. They will be able to determine whether the CRT is bad or not.

Green bulb or tube


Let me know the symptom in detail.
Green bulb (CRT) gives high bright light and tv goes to standby? Do you see few horizontal (retrace) lines while this happens? If yes, you need to replace Green bulb (CRT) of your tv.
Please mention exact model number of tv to guide you further.
and what IC chip you replaced in tv?

Toshiba colours gone wrong


Yes it is repairable. One of two things is wrong. The color wheel is going bad or the DMD board is going bad. These are the most common repairs needed for a Toshiba. I hope this will help.

The green gun in your picture tube is set a little too high. If you are experienced in removing the back cover of TV's,etc., you may try to find the drive and/or bias controls either on the circuit board that plugs on to the neck of the picture tube or mounted on the main circuit board of your TV. These controls are usually labeled. If you can find them, locate the green bias or drive control and back it down a little while watching the picture through a mirror. A slight adjustment may correct your problem.tJIS IS CALLED GRAY SCALE ADJUSTMENT. BE CAREFUL THERE ARE SOME HIGH VOLTAGE CIRCUITS NEARBY. WORK WITH ONE HAND AND USE AN INSULATED TOOL TO MAKE ADJUSTMENTS I hope this may help you.AGAIN BE CAREFUL!! Stargazer
