  ...Recently they brought it to me for repair
VCR JVC, something like that
sophisticated, with Karaoke, two inputs
for microphones and volume control
(!).                                     
  The poor fellow's symptoms were very
sad: after switching on for 10 seconds
The LED light came on - indicator Power
On,  and then switched to red -
thereforeOff. No more signs
did not give life.                        
  But one thing consoled me - plus 5 volts on
the board was supplied, otherwise the LED would have
didn't burn. It looks like standby mode is useful
thing.                                   
  It also became known that the owner of this
Miraculously, I once stuck a video cassette there,
but the tape recorder refused to output it 8(
andowner "used force."              
  Here I will deliberately leave out the insignificant
I will tell you the details of troubleshooting
only that while the smart uncle tried
remove the cassette by force
I tried to do it myself, but,
because the cassette is firmly stuck in it,
the engines stood in one place, which led
to an overload of the voltage supplying them.    
  So, the topic of our today
conversation - break resistor.  For these
I'm lucky with figs - this is the second time since
This is what I encounter.                       
  In short, when certain
parameters flowing through this summary
current, it brazenly burns out (it means
disposable :)                           
  It looks like a regular summary at 0.125
W,  only has a blue tint.  On
scheme (which is almost always missing ;)
is designated as a fuse.         
  So, this summary stood between the conclusion
one of the windings of the network transformer
and a diode bridge. Truth beyond that
supply voltage to the board
5,9,15 and 24 volts are supplied. But it's 12
volt - goes purely to power the engines.
There are three engines in total. One is in the head,
the second - spins the cassette, and the third -
carries out manipulations with the tape drive
mechanism, pushes out and swallows
cassette, etc.                            
  After I soldered this vile
break and replaced it withjumper
from thick wire (it will burn now! a
I'd better put a fuse there)
and turned on the video recorder - everything started spinning,
spun; the device began to swallow itself
and throw out the cassette, rewind
(automatically! :)... Then I
turned it off, manually removed the cassette and
set all kinematics to initial
point.  The fact is that the cassette (still
then, the owner) got stuck in the middle
the process of ejecting it, and this process is on
middle and stopped.  Which is very wrong
liked it highly intelligent
Japanese technology. After I took
pressure shafts and rollers in the initial
position, tightened the gears - everything was fine
work.                                
  So - keep in mind that in their
technology uses such sneakysummary,
which break off when overloaded, and this
has no external effect, not even
turn black!  I have a vintelator right now
spins - in series with the engine
a two-watt 47 ohm booster is included. And
nothing, the current heats up a little.  But not
turns black :) Here!                          
  Well, that's enough for today.  Good luck to you
repair! :)
