You will have to have someone who knows the Philips set to service it at the
component level for you.

There are most likely some parts that have become thermo sensitive with age.
The fault is most likely in the video path in the respective colour channel
that is causing the fault. Going by your description, I doubt the CRT is
bad, therefore the service cost should be relatively reasonable.

This is why before buying any used TV, it should be properly checked before
paying out for it. Sometimes a repair cost can add enough to the price to
make the total cost to be around the cost of buying a new set.

From many years of experience, I found that people normally sell their old
TV set when they have a problem with it. A TV is usually the type of device
that when it works properly there is no reason to change it. When the set is
more than about 5 years of age, it generally may not be worth to service.
The cost of servicing can easily cost more than the effective value of the
set. After investing money in to an older set, there are hundreds of other
parts inside, that can easily fail from age and use.

I've bought a Philips 24PW6324 second hand, lovely TV, except:

After about 1/2 hour use the brightness on the red gun seems to increase
massively, leading to very red/orange skin tones and blurred red images. If
I look at some white text, it seems to have a red halo pushed up and to
right about 1/4 inch. White still stays white, and blues and greens look
normal.

When the TV is not doing this, I think I can see some cycling up and down of
the brightness on the red gun.

Anyone any general suggestions as to what might be wrong, before I call my
local electrical shop and see if they might have a look at it?
