posted by baravelli on Feb 09, 2008
the tape inserts,moves down, starts to feed, as if to play-then stops and ejects cassette
I have the top cover off so I can see the action-
the unit may have been dropped???
it was working ok-
i shipped it to a customer last week but it didn't work when it got there

GuruThese old Quasars (matshushita made) have underdesigned power
supplies. The electrolytic caps on the output voltages need high
voltage ratings. Does it make a high pitch sing? Your unit
is running out of power when it gets to the most difficult part of its
loading sequence. Try replacing all those caps. Some guy at
Matsushita (Panasonic, Magnavox, Quasar) designed many many VCR's and
it took him about 10 years to learn that electrolytic caps don't work
too good at the high frequencies that switching power supplies have
gone to.
