Hi all,
I have a icf-sw77 that has been working fine for years. I lost AM
receive
last night. FM works fine and I checked different antennas, jacks,
power
and everything else I could think of.
I came home from work and tried it again. I can scan through the band
and
toggle freq. no problem. I did see it come back a couple times for a
split
second and then go dead again.
Has anyone had this problem before?
I called sony and they said.
repair flat rate = $130.00
exchange = $383.00
I would like to trouble shoot it before sending if anyone has any
ideas on
this???
It seems to be in the jog dial area. When I push in the dial hard it
gets
intermitent.
I did get a rapair cost quote of $130.00 from Sony.
Problems like that are often caused by one or more bad solder joints. If
you know how to open the case of your SW-77, you might be able to locate
the specific area on the circuit board which is most sensitive to being
pushed with an insulted tool like a tooth pick or plastic stick. If you
do find a suspect area, look carefully at the solder joints with a
magnifying glass for evidence of cracks or a dull appearance to the
solder, which should be shinny.
There is also the possibility of a loose connection with one of the
wiring connectors, especially the ones on the ends of ribbon cables. Try
wiggling them to see if the problem goes away.
BTW- Has the radio ever been dropped? This could have damaged a circuit
board or caused something to become loose.
I will give it shot! thanks
It is still doing the same thing. I looked all over in there for cold solder
joints around the jog dial but I don't see anything. I have had the radio
for 3 years working fine and I have never dropped it. Man I really don't
want to drop $130.00 on this radio as I spent enough just to get it.
The best way to cut your losses is to sell the radio as is to someone
that wants it for spare parts or can fix it. Then use the sales money to
buy a good used one.
