You have a convergent problem, where the red, blue, green projector lamps are out of synch. See: http://www.youtube.com/watch?v=esk4nYZKFcg for a pictorial on how to fix convergent.

My zenith tv model SR2075DT had this continous Red tint. I have tried fixing it through settings and NOTHING works. Someone please help me


It is likey the blue lamp has failed.
They are relatively cheap to replace and you can buy them online.
There are dangerous voltages inside the cabinet.
If you can see the lamps through any of the vents, you may be able to see the lamps. Check to see if blue or green are not working. There should be three separate lamps. Red Blue & Green. This is assuming the colour is like that on all sources.
If it is only on one source, check the component cables in the back of the TV.

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 a 60 inch Philips tv and the picture is kind of blury and a little red. What is tha caused from?


THREE possible reasons for this:
I will list each and describe for you:

1.) If redish picture go to a black and white channel; is the screen somewhat red or black and White? This is adjustable from inside the set.

2.) If colors are skewed or look like they have a red outline it may be a convergence problem. See attached photo.

3.) Some of these sets develop a problem with the coolant which is used to keep the face of each of the three tubes cool; it is called Glycol. You would have to remove back cover and with set on look into each of the three lens (red,green,blue) to see if you have a clear red, green and blue picture.

Which best describes your problem?

Picture is OK, but colors are off and there is a blue star background that shows on dark colors.


Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.
