Intermittent Buzz from relay on IF I/O board in P3 any fix ?

[Clifford Hynds]

Hi,

Intermittent Buzz from relay on IF I/O board in P3 any fix ?

I have completely re-soldered the board and checked it as the current
schematic and all seems ok,

Sometimes it will buzz continuously other times intermittently, really
annoying. and the display jumps at the same time.

Any ideas?
