It is the fault to its video output card. This card ca be located at the back of the picture tube, directly plugged on on to it. Check it for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder. This must solve the problem. The fault is called on color predominant screen.

Toshiba tv 62jm9ua has a green picture screen instead of a blue picture. Can you please tell me if there is anything that I could do to fix this issue?

Problem with the Toshiba 50H13 50 in. Rear Projection Television. Green tint


The tubes have aged and the colour balance between the tubes has shifted. You will need to redo it using a black/white test image: first the black (the cutoff point), then the white (the gain) on each tube - always start with the green colour. This is done on the final video amplifier of each tube by adjusting the corresponding semiadjustable resistors.

Friend gave us a toshiba a3642 tv,the screen is green,is this worth fixing?


Hello

Your TV is has no green cathode voltage at the picture tube pin. There are three electron guns for every colur picture tubes, Red, Blue and Green. These three guns together mixes all colours we see on the screen. If any one of them happen to be not working properly, that colour must either be lack, of excess. Voltages at the above said three colour cathodes are somewhat equal to each other. if voltage goes down, the emission of that particular cathode will rise, and as a result that colour will be predominent on the screen.
These cathodes are fed voltages from the video output stage of your Tv. This stage can be located at the neck of the picture tube itself, as a card pluged onto it, called the base card. There will be either three trasistors to drive the each above said three cathodes, in some sets, there will be independent three ICs or only one IC capabale of driving these three catodes will be used.
You just open your TV, after unpluging it from the wall power socket. You can locate the above said base card, at the neck of the picture tube. Before doing anything, check very keenly for any loose solderings are there on the CRT base board. It is very difficult to locate the loose solderings, as they may be microscopic in size. So I advice you to resolder all the soldering points on that board, by applying a little more solder, without making any short circuit bridges in between.
In most cases. this will solve the problem. If not, check the voltages at the above said three cathode, wheere tey were marked on the PCB itsef as R ,G & B. You can see that the green cathode voltage of your set will be much lower than the other tow, in your TVs case. If so, check the resistor connected to the revalent Ic or transistor, whichever it may be, for open circuit. that is check whether it has burned or not. If that resistor is Ok, replace the transistor or IC, which drive the green cathode.
If you wants furthermore assistance, feel free to get me through Fixya. OK.

I'm having a problem with the color green being distorted on my TV. Is this a color tube issue, bulb issue, lamp issue?


This is a picture tube type TV. No lamp.
You don't describe the distortion.
A colour green picture that is twisted and shifted away from the other colours is a convergence problem. see Projection TV Convergence on this site.
If the green is smeared, out of focus, larger than the other colours like a halo around objects, things like that, it is the green picture tube. Sony has discontinued most of the picture tubes so you may not be able to get this fixed.

Problem with a colour display on Hisense tv


If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

Change posistor in the degausing circuit.

Loss of colour


With the set being 12 years old, I'm sure the picture tube is near the end of its useful life. You probably have a defective semiconductor, either an IC or transistor that has gone up giving you no color, but with the green picture, it is not likely worth repair.
