Need to clean and resoldering works.Cold solder issues - each
component is soldered into small
holes on the printed circuit board which in turn connects said
component to the
other components. Due to time, heat, use, some solder joints would be
cracked
or loose. It is possible that the cold solder is still minimally
connected
(hanging by a thread). When the receiver turns on heat would be
generated which would
be sufficient to further loosen up the solder joint to the point it no
longer
provides electrical contact. Jarring the unit creates movement inside
enough to
re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly
probable that there are no defective components. As you have surmised, it is
possibly a loose connection, solder joints are "connections"
except that molten soldering lead is used to attach/connect the component to
the board, "loose connection" in this sense is equal to "cold
solder".
Again on the assumption of no defective parts, then seeking a more
experienced
buddy for the soldering might be to your advantage. This is of course
in
addition to the possible electrical hazards when repairing....If i have
helped,please click to rate.It is the only way i get paid for my work...
Good luck:
