Do you have static removal of some type installed on the antenna lead in
? Static can wreck a silicon chip in a hurry. I fyou know anyone who can
do a diagnostic on your radio I would sure ask them if they would. I had
a scanner get zapped once because of static on the antenna. It would not
scan trunked systems all of a sudden. I finally turned it in and got my
money back.

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???
