I think the answer might be " Throw it out. Buy a new one. ", but I'll ask
anyway.
I have a Sony " Mini HiFi Component System " ( what a laugh - model FH-B411
just in case ) which has a push-button preset radio as part of its features.
Last weekend without me touching anything it went to white noise on all
bands and whatever I did couldn't get it to tune anything. Its CD player and
tape deck still work, so the main power supply and amps are working I guess.
My knowledge of electronics is a shining symbol of ignorance, and radio
communications is pure black magic to me, but I know enough to be a menace
to public safety. So I took the cover off and couldn't see anything obvious
like insects or any appreciable dust build-up ( I vacuumed the boards
anyway ). The areil connections were good. The auto-tune routine goes on as
normal but it goes straight past well known frequencies and doesn't get a
hint of anything. White noise all the way. My guess is that it has a
frequency generator inside which it uses as some sort of phase-lock thingy
to tune into stations. If this is buggered then everything else is useless.
So, as this radio is 9 years old and has been on for about 15 hours a day
since new, is it likely that the silicon has simply given up ? Does anyone
out there know if this is a common fault that is fixable ?
I'm not a cheapskate, and I would happily buy a new one except this one has
' propper ' wooden speaker boxes and sounds a lot better than any new ones I
listened to.
Thanks for any help, abuse or sloppy kisses,
Dean.
