- TROUBLESHOOTING
TiPS FOR TEST CHIPS
-
- 1. The most
common cause of test device not functioning
properly is from poor soldering or a bad
connection during installation. Inspect
connections before applying power to the
unit. Solder connections should be shiny and
smooth. If connections are dull and/or rough,
it could be a "cold solder
joint".
-
- 2. The
second most common cause of test device not
functioning, is that the device is not
installed in accordance with the instructions
supplied. Some test chips do not align pin 1
of test device with pin 1 of unit under test
(Zenith ZF-1). Follow instructions "...to the
letter". Be careful not to bend pins under
chip when installing.
-
-
- Do NOT try
to "second guess" the instructions. Sometimes
we substitute different brand test boards or
chips. If they are "physically different"
than the supplied schematic, we'll typically
included an additional schematic showing key
points, wires, etc.
-
- Do NOT try
to install with other than the recommended
and supplied schematics diagrams. Do not try
to "fake it". Models number have to be
exact...just not close. 8600 means 8600 NOT
8602 or 8610.
-
-
- 3. If
installing the test device "piggyback" onto
another chip, make sure that the pins of the
test device are in contact with that of the
"host" chip. Clean pins of host IC and solder
on a socket first. Then plug the test chip
into the socket.
-
- 4. Double
check all work. A mistake in wiring may cause
the test device to be damaged, and perhaps
the box. Check your work carefully before the
box is powered up.
-
- 5. Once
installed correctly, if unit fails to work,
make sure that it is connected to a signal
that is compatible with that of the unit
under test. I.E., a Zenith box will not work
with a Jerrold type signal.
-
- 7. Sometimes
the cable box/descrambler itself, is
defective. If the box worked before you
installed the test chip, and you suspect your
installation as faulty, remove and reinstall
test chip. test chip CANNOT resurrect a dead
box if it has "physical damage", i.e., been
dropped, spilt beer on (oooh, waste of
beer!), set on fire, etc.
-
- S. To
protect pins of test chips which are removed
and replaced often, install test chip first
into high quality socket.
-
- 9. Test
chips, typically, will allow reception of all
channels that the box is capable of
receiving. This means that PPV or Premium
channels may or may not be enabled for
testing. Sometimes a second outboard
descrambler, using a different scrambling
method is required. Some test chips will
reprogram the apparent locations of some or
all channels. The box will still decode all
channels, however, they may not all be in
sequence. This is not a problem, it's just
the way the test chip works.
-
- 10. If the
box still does not operate, you must now
determine whether (1) the box is at fault (2)
the test chip or module is at fault (3) you
have done a bad job of installing or (4) a
combination of (1) through (3). If the box
operates on all but a few premium channels,
the cable company may be using a different
descrambler to decode those channels. If this
is the case, the installation is OK and the
test chip is operating correctly.
-
- If not, then
remove the test chip and return the box to
its original condition. You may have to
bridge cuts made on the PCB or re-install
jumpers, etc. The easy way to do this is to
follow the installation instructions for
installing the chip, only do it in reverse.
Start at the end of the instructions and
remove instead of installing, uncut instead
of cut etc.
-
- 11. Once box
is returned to original condition, connect
cable company cable TV, and power-up box. The
box should operate as normal. I.E., you
should be able to receive some sort of
programming. If nothing happens, double check
the work you just performed. If the box has
been returned to normal condition, it should
work same as it did before you began work. If
it does not, the box may be defective, Or YOU
may not have programming going into the box.
-
- If the box
received channels before the installation of
the test chip, but does not work now, you
either have not returned the box to original
operating condition or have damaged the box
during the initial installation. If you have
incorrectly installed the test chip or module
the first time, you may have damaged either
the box or the test chip / module or
both.
-
- 12. If box
works normally now, i.e., receives some
channels, the box is OK. Now follow the
instructions to the letter, and reinstall the
test chip or module. Be sure to follow the
instructions exactly. The majority of
installation problems can be traced to
improper installation. Very rarely, the chip
or module will be bad.
-
- 13. If after
re-installing the chip / module in a working
box, it STILL does not work, contact us for
return authorization (RMA number) to replace
the module or chip. We have the facilities to
check the chip or module for damage.
-
- If the chip
or module is defective from manufacture, we
will repair, reprogram or replace it at NO
CHARGE to you. Chip returned without RMA
numbers are subject to being returned without
explanation (refused). Call or e-mail us
first. Sometime we can answer a simple
question and save you some money
(postage).
-
-
- EXCEPTIONS:
If the chip or module has been installed
incorrectly, or has been damaged in any
manner by the person installing the module or
chip, i.e., static damage, missing chip legs,
internally damaged (burned-out) from being
installed "backwards", cut traces on PCB
boards, missing parts, dropped kicked,
stomped on, labels or ID number(s) removed,
somebody else's sale (not our parts), obvious
physical damage, burn marks from overheating,
added wires or other electronic parts, sanded
off numbers, or other damage inflicted by the
installer, it will not be replaced, but will
be returned to you.
-
- Chip or
modules damaged in transit and not insured
will be returned. Package the returned item
at least as well as we sent it. Warranty on
chips or modules returned to us, but NOT
PURCHASED from Extreme Media, for repair or
replacement, will not be honored.
