A
while back I wrote about how some changes were coming if you are a Time Warner
Cable subscriber. The company is
dropping the analog cable service and all subscribers will be required to have a
special digital adapter if they do not already rent a set top box from the
company. Well, the deadline is fast
approaching and from my emails and comments it looks like some people are
having problems getting these adapters to work.
Just
to review: Ever since the cable companies began providing digital cable, a
system that was much superior to the old analog system, the companies have
essentially operated two separate systems. Initially this was done so customers
with older TVs could easily hook up their sets.
Now that most people have digital wide screen TV sets, the analog system
is no longer required.
Many
customers have several TV sets connected to the cable. Some of the sets make use of the set top box
but others, up until now, could be connected directly to the cable using the TV
set’s internal QAM (cable) tuner. By the
end of April, the QAM tuner will not be compatible with the cable signal so a
special digital adapter, provided free by the company, will be required for
each cable-connected TV set if it does not use a set top box.
For
most people, setting up the digital adapter is very easy by following the
directions that come in the shipping box.
However, some have found that no matter what they do they can’t get the
adapter to work. In most cases the root
problem is in the quality of the cable signal running throughout the house to
the TV sets. The digital signal is not
as robust as the old analog signal. A bad
cable or a cable of inferior quality could pass the analog signal and the only
issue was a less than perfect picture.
Digital signals are prone to the “cliff effect.” Essentially this means you have a perfect
picture or none at all. So if the signal
in the cable is not adequate, the TV set will display nothing.
There
are some fixes for this situation. First
make sure your cable runs are as short as possible. Invest in higher quality
coaxial cable for use within your house. The cable guy may be able to help you. Keep the number of cable splitters to a
minimum as each one will weaken the signal passing through it.
If
all else fails call the cable company.
It is in their best interest that you are a happy customer.
