Either your tube lenses are dirty or your focus control is bad.

How do i fix a non responsive tv set?


Do the ballast first. That should get the picture back. The main board controls everything else.

Poor viewing quality


By poor color quality, do you mean that if you turn the color control all the way down, the black and white picture is more like black and red, green or blue - or do you have a good black and white image? If the B&W image is good, and the TV is an old (8+ years) one, maybe the mirror inside the set needs a good cleaning - especially if there are smokers in the room. If you have a B&W picture that is tinted, then you may have to go into a service menu to adjust it back to a better picture. Hard to guess the problem without more specific description of symptoms.

I have a phillips rear projection tv model no 55PP8620/79. Its showing a a red haze and poor picture quality. How do I fix this?


If the red haze is not convergence---that requires parts.

The set has three picture tubes---with set unplugged and back cover removed clean the three large lens that are topside---as for the red haze a quick way to know what is wrong is with set on turn the color to zero----what color is the screen? Should be black and white--if red to some degree tracking or screen controls may need adjusting inside the set---Yellow picture in that situation is a different issue.

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?
