My polaris seems to have what has been described here as the "bad S+H
capacitor permanently detuned scale problem ".... this appeared when
i got it back from a repair shop. Could something that they did
there 'blow' the caps? such as soldering an additional battery to the
main board to supposedly save the memory when it was taken out of the
unit? would this have temporarily doubled the voltage in the system?
The tech claims that the "program is corrupted" referring to the
programmed sounds,explaining why they sound out of tune . but he cant
apparently reload the sounds, the unit wont take the new cassette
feed data. ( or else it does but that is simply NOT the problem )
he doesnt say muchabout the capacitors.. but I dont think he knows
for sure... Ive tried to tell him about the S+H caps, but its as if
they dont want to listen to what other people say. But the unit played
OK for tuning when i brought it in.... any ideas on what would cause
the caps to fail if supposedly only a slider and LED were replaced.?
last i heard they just want to give me my money back along with a
disfunctional unit (the place is a large 'factory authorized 'music
equip. outfit for a lot of southern New England.} I wonder what has
happenned.
