Is there a way to test in circuit if a chip is broken or not using a
multimer or some_other_instrument_lot_cheaper_than_osciloscope ?
Measuring temperature of chip while it has been working for a while
should be indicative, but how?


Some chips run surprisingly hot, so unless it gets hot enough to split the
casing there's no guarantee this indicates a fault.

All the test gear in the world won't tell you if a chip is faulty if you
don't know what its supposed to do - and none of us do either because you
didn't tell us!
