TV tuner replacement advice ?

[[email protected]]

Aloha ,

We purchased a 29inch Toshiba flat screen tv with a undisclosed
fault .

Occasionally when switching channels the audio track is lost and
replaced with static
Then , after about 20 seconds (always exactly the same) , the audio
track is picked up again .

Finding that we do not watch TV anymore it has been decided to sell
the TV . But We will not pass it on in this condition , it was
annoying to us as the buyer and we want to pass it on in better
condition than we found it .

We have read mention that the TV controller unit (the part inside the
case that has the aerial connection for the TV) is replaceable with
many other versions of the same .. this is encouraging .

But is the replacement of the Tuner really quite straight forward?

And does the TV tuning fault as described indeed refer to the function
of the TV tuner ?

cheers

That sounds like you are describing the RF tuner component.

You didn't explicitly state this but if I can assume ONLY the audio
is the problem, i.e. the video is fine, I doubt that the RF tuner is
your problem.

The tuner module could cause your symptom but I won't advise that it is
the only component that can do this.
Since I do not know what a Flat Screen TV really is it's hard to tell you
the degree of difficulty replacing items inside.

How about a model number??? Is the set a digital tv? If so, the
sound could possibly go out without affecting the picture. Frankly,
it doesn't seem like the tuner if the picture stays ok as that is
usually much more sensitive to any type of tuner problem.

Is there an AFC automatic frequency control switch? If so try switching
it off to see if the set changes channels faster.

The actual tuner will be a small metal box with the RF connector attached,
there should be a tag on it having appropiate part number, if in doubt
contact Toshiba America - Hawai'i division for assistance. Give tham
complete informatin regarding make, model, and chassis number (All available
from the back cover of the set). Mahalo!

Yes its just a Audio lag .. and only sometimes .. the picture loads
AoK but we gat a static noise for about 20seconds then the set seems
to find its audio signal and the sound is correct again .

The static is allways the same event in sounding and duration , and
the TV allways finds the audio signal after 20seconds , but only say 1
time out of ten does this happen .

Its just a std CRT TV really ,, i shound't have mentioned the flat
screen except i guess if it were not a flat screen we would prob chuck
it away without second thought .

Nope not digital , just std TV .

Nope couldnt see one .. know what you mean tho .

The channel switching is good in speed , its just 1 time out of ten
(varies in frequency according to i dont know what) it will not tune
to the audio track . Video will load up 100% but the Audio will load
as static for 20sec or so and then the TV allways loads the clear
audio track .

Have you ever replaced the RF unit with a version from another
different make/model set ?
We have found the Sony tuners to be the best for signal pick up around
these parts..
