Here are some of the most common problems with a CRT TV
by agha raza aghaCathode ray televisions were some of the most widely used
televisions in history. They were immensely popular, as they were the only
sensible choice in the technology of that time. Now smart LED TVs are the popular genre and people are regularly going
on the web for LED TV online shopping.
But you cannot help but feel nostalgic with the thought of them. For many of us
especially people born in the 80s and 90s this television represents a part of
our childhood.
But, time and technology waits for no one and the Smart LED TV is much better than the
CRT TV. But what were the reasons that people moved on so quickly towards the
new technology. Well here are some common problems that almost all CRT TV users
have faced in their lives.
There being no image
but a single color
A very common issue with cathode ray tube TVs is no picture.
If you are facing such a dilemma, first check the obvious stuff, i.e. check if
your TV is correctly plugged in and receives enough power for service. If the
power is OK then check the settings for the video (like sharpness, brightness,
contrast and picture settings). If the settings are perfect, then the video
cable and hardware can be the cause of trouble. If the basic diagnosis is good,
then it might be time for a competent TV repair person to have a look at your
TV.
When the images are
not lined properly
With CRT TVs, this is a very common image issue. The failure
of an internal circuit called the convergence circuit normally triggers it. The
circuit has convergence ICs that produce the problem of bowed image while going
bad. Poor or flawed soldered-in fuses and resistors may also cause image
distortion often. This form of issue can be easily repaired at home by a
technician or a PRO.
A bright horizontal
line when turning on
It occurs that a single thin horizontal line appears on the
CRT TV screen several times. A defective yoke with a faulty or burned coil
inside it may be the probable cause of this problem. Loose contact between the
yoke and the main board may be the other possible cause. A faulty capacitor may
be the third possible cause.
A burning Oder
This is not an issue that is really general. Cathode ray tube failure is the most prominent reason. The small crackling noise is due to arcing at high voltage. The potential cause behind the burning smell is caused by the burning of insulation. In such a case, unplug the TV from the power outlet immediately. Call a competent TV repair person to get it fixed.
Shadows of colors on
the edges
If you have or previously owned a CRT TV, you must have
observed a vivid shadow on the sides of the television at some point in time
(can be seen as reddish orange shadow in the picture). It is mostly due to
every magnetic system near the TV being present. Magnets positioned near a CRT
will damage the "shadow mask" of the package, which will cause in
that area the wrong colours to appear.
