What is that the smell of burnt electornics called?

[bleed-22]

I propose the term "electro-fry".

As in "I smell electro-fry."

There has to be a term everyone agrees on. Not the usual stumbling...
"You know that smell when electronic equipment goes bad or takes a
power hit."


Ideas?

I refer to that smell as "applied empericism".

I don't know, but I have actually seen the high-voltage transformer in
some older Samsung (I think) manuals referred to as the "fryback"
transformer.

Or.... in a early 1990's Panasonic Industrial Video Camera manual they had
an
"AutoFUC#us" PCB ;-0
never could locate that board

I've seen this in a service manual that was (understood to be) translated to
Brazilian Portuguese. Duh and LOL at the same time.

I've got a Technics SA-500 receiver open on the bench. On the p.s. section
of the board it has silk-screened: "REGURATOR."

BTW, (I should make a new thread?) if anyone has a schematic for this one,
there's a transistor -- Q-751, a C1398-- on the tuner section of this one
which is shorted. I'm thinking it's a voltage 'regurator' for the section,
but seems pretty 'hefty' for the purpose. Any ideas as to why that one
would fry? Everything around it looks good. The amp section works fine,
but the tuner (both AM & FM) started getting intermittant before it went out
completely. I'm hoping there's nothing downstream that's gone south, but
need to order the part before I can find out(?).

Hi!

"Expensive". Well, usually.

Apparently the transistor went bad on its own. Replaced
w/NTE152...everything's back...been burning it in for the last couple hours
and seems fine. I carefully monitored the temperatures in the section
before buttoning it back up...nothing smoked or even got hot.

I did notice almost *no* heat sink compound on the original--just a 'wet
spot--where the transistor clamped to the heatsink. I liberally goo-ed it
and wiped off the excess before installing the assembly. Hopefully it's now
good for another 30 years or so.

now you see that was your problem!
the smoke escaped out of the original
part and failed to operate afterwards!
didn't any one ever tell you that you
can not let the smoke out!

Couldn't have had much smoke in there...never saw it come out....

Sometimes it's expensive (at the customer's home)

Sometimes it's OOPS (at the shop)

Luckily we don't get too much OOPS.

That would be ``GAK``

 

[Bob Kos]

It's smoke. The perverbial colorless gas that operates all things
electronic. As you probably already know, once it leaks out of a sealed
electronic system, the system fails. If it becomes overheated, it will turn
white in color and become visible to the naked eye. Not to be confused with
black smoke. That's the plastic cabinet burning....

It's actually called "magic smoke." As Bob Kos mentioned, it's what makes
electronics work. Once you let the magic smoke out, you have troubles.

Thanks...as explained--fixed it. Dunno for sure what it does, or why it
died, but works fine now.
