TV problem - Green Screen

[Grant Cooper]

I'm having problems with my TV set which is fairly old. The screen is
now showing a significant greenish tint on all channels which cannot
be prevented by adjusting contrast/colour/etc.

Does anyone know what is causing this problem and is it common?
Moreover, is it easy to fix and does anyone have an idea of how much
it would cost.

Thanks in advance for any help.

Grant:

The problem you describe could be a few things. It could be a bad pix tube
(Red Gun most likely) or the driver circuit for the red gun. Since the
picture is made up of RED-GREEN-BLUE and you are seeing green, it is most
likely that you are actually seeing GREEN-BLUE (No RED). More than that, it
would tke some troubleshooting to see if it is the gun itself or the driving
circuit that drives the gun. Could be as simple as a $0.25 resistor or as
expensive as a pix tube. I'm sure if you provided the make and model#
someone might have some more detailed information.

The most common cause on the Sony sets are the CRT's going bad. After
the set is about 6 to 10 years, this is common. It is also possible
that there are some defective components in the CRT drive circuits.

How can you come to this conclusion without knowing any specifics about this
set, such as model, brand, and age?

For all we know, it could also be a Zenith with their infamous defective pix
tubes, or a 1986 NEC with a worn pix tube.

To the original poster: We need to know more information before we can give you
educated guesses. I call the answers that may be given guesses because without
actually being able to look at it and diagnosing it, we cannot give you a
definite answer. The guesses would be educated because they will be based on
actual experience, depending on specifics like set age, set model, set brand,
and usage.

You should take the set in for a proper estimate, so that an intelligent
decision can be made. If the estimate is more than about 15% to 20% of
the replacement cost, and the set is more than about 6 years old, I
would not proceed.

Reinhart/Rich/Jerry - Thanks for your help on this matter.

It's a Philips TV, FSO Vision, type 15CE1518/05B. The TV was
second-hand when my girlfriend bought it, so no real idea how old it
is, but it has "Made On Britain" on the back, and I know we haven't
had any manufacturing industry here for twenty odd years.....
