Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
TV's always make a clicking sound as the Main Power relay turns
on. If you are asking why it then doesn't turn on, it can be many
things. The processor monitors a number of circuits and if
something is amiss, it turns off. The most common failure is the
high-voltage circuit and if the set is any where near 10 years old, I'd
plan on replacing the flyback transformer as well as anything else it
damaged while failing.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope Ya Fix It!
