Re: no tv channel

It has been a number of years since I worked on the FV series of Sony. I
used to work in Sony warranty service.

On the Sony 20FV12, if I remember correctly, the IF and tuner are separate
modules. They are also very critical to work on. As for the cost of these
modules, they are a lot more expensive than $32 !!!

In his case, the fault can be a number of other things. But, these modules
can not be ruled out.

Why would one ask for an estimate based on the age of the set? Why not get
an estimate regardless?

Since the IF module is integrated into the tuner, there is not much reason a
person with reasonable electronics knowledge and decent soldering skills
could not attempt this repair. If the set gets no signal when switched to
the tuner, and the audio/video switches over ok, it is unlikely that the
problem is in the video select circuit. If the supply voltages are at the
tuner, it would be reasonable to replace it.

Sure, as I stated in another post, having the right equipment and knowledge
would allow a more certain diagnosis, but many techs would not even bother
to inject IF and would just change the tuner.

A DIYer could take a $32 gamble, replace the tuner,and if it does not fix it
not have lost as much as an estimate charge. He could then maybe even trade
the tuner for a real estimate. I'd likely take that deal.
