CAUTION!! CAUTION!!
- CHIP IS
STATIC SENSITIVE. USE GROUND STRAP WHEN
INSTALLING OR HANDLING THIS I.C.!

- VIP TEST
CHIp INSTALLATION
-
-
- This test
chip functions in TOCOM 5503VIP and 5507VIP.
Unplug unit from power. Using a Phillips head
screwdriver, or a #7 TORX tool, open the unit
by removing security screw(s). Orient the
decoder so that the front panel of the unit
is facing you. Look on the right hand side of
the printed circuit board (PCB), for a 28-pin
chip, usually in a socket. The chip is
typically marked: 201-0059-003. Note the
direction in which the chip pin #1 index is
oriented.
-
- The index
mark can be a dimple in the chip, a notch, or
any other type of marking that denotes the
pin number 1 end of the chip. Orient the box
so that the pin located at the upper left
corner of the chip is pin #1 is away from
you. Looking down on the chip, pin #1 is
closest to the upper left corner. It is
critical that the replacement chip be put in
he same way as the stock chip is remove,
i.e., with the pin #1 at the upper left
corner.
-
- If the chip
is socketed, remove it by using a IC remover
tool, available at Radio-Shack, or by very
carefully placing a small screw driver under
one end of the chip and gently prying up a
small amount. Do the-same for the other end.
Repeat procedure until the chip is almost
loose. The chip can now be removed by hand.
If the chip is soldered directly to the PCB,
it will be necessary to remove the chip using
a solder sucker and solder pencil. A low-cost
tool can be purchased at Radio-Shack for this
purpose. Do not use solder wick to remove
solder unless you are willing to risk heat
damage to the original chip. Solder in a
28-pin socket, orienting the notch of the
socket same as the original chip.
-
- Once the
chip is removed, and a socket is in place,
take the new test chip from its shipping
container, and place it in the socket on the
PCB. The orientation must be the same as the
removed chip. If not, the EPROM and decoder
will be damaged when the decoder is plugged
into power. Make sure all pins are seated
securely into the socket, and that none are
bent out or underneath the IC. Return the old
chip to the shipping container to keep safe.
Test Chip Installation is now
finished.

- RESTORING
REMOTE FUNCTIONS
-
-
- Unplug unit
from power. Remove security screw(s) as
above. Orient PCB per diagram. Locate
battery. The battery is a silver colored and
shaped like a disc. It stands upright on the
PCB to the left of the test chip location.
There are three (3) legs of the battery that
are soldered to the PCB. One on each end and
one in the middle of the battery. Do one of
the following: (A) cut the center leg, or
using a small wattage (35W), (B) desolder the
center leg from the PCB. Remote control
function and channel assignment is now
restored. Reassemble case reverse
order.

- PROCEDURES
TO TURN ON ALL FUNCTIONS & CLEAR "JAMMED"
COMPUTER CHIPS WITHIN CONVERTERS. 5503VIP and
5507VIP
-
- 1. Make sure
Converter is unplugged before proceeding with
EACH step. Also: be sure you have installed
your new Chip first.
-
- 2.
Temporarily short out the battery, using a
small 6" wire with two small clips on each
end clipped to both positive and negative
leads of the battery. This will not damage
the lithium battery.
-
- 3. Now take
another 6" piece of wire, and find diode
CR-18. which is directly behind battery,
locate positive end with red/orange band. One
lead of your wire will touch the positive end
of that diode(with the band on its end) and
the other end of your wire will touch
resistor D-108 or W114 or located 1" to right
and back towards the Tuner. This will clear
all computer microprocessor chip of internal
capacitance and any stray voltages (reset
RAM). Also chips will loose any previous
programming instructions stored, so that your
unit may now accept new programming necessary
for proper operation.
-
- 4. Plug unit
in, make sure you have disconnected any wires
left, turn unit on and observe for 00 on
readout. If you have it, you are done. If
not, proceed as follows. Unplug unit first,
short out the battery temporarily again. Now
go to the front forty pin processor, locate
pin one and ground this pin to the chassis
(tuner cover). After you have done this, make
sure all wires have been removed, turn unit
back on after being plugged in, observe for
00s, if you have them, you are done. If you
do not have 00s, continue to next
step.
-
- 5. Repeat
steps in part four again, up to two more
times if necessary. Now, making sure unit is
unplugged for ALL steps, with battery shorted
out, proceed to touch a wire from pins one to
ground on same chip as in step above, then to
pin four. Repeat this back and forth two or
three times, then plug unit in, turn on, and
observe for 00s. What you have just done is
literally shaken the data stream processor's
memory loose. Now, with 00s when turned on,
you are done. If not, proceed.
-
- 6. If 00s
have not been obtained as yet, you have a
possible "frozen chip". Unplug unit, obtain a
piece of aluminum or tin foil, cut a small
piece the length of the forty pin chip and
about 1" in width, short out the battery,
touch the tin foil between pins one through
pins twenty and hold for 3 minutes. Make sure
that the 20 pins on each side do touch each
other. This will allow the chip to return to
its normal, factory program. Now remove
jumper from battery, allow unit to be
undisturbed for about 30 minutes before
plugging in and observing for 00s. If you
have them fine, if not, you may need another
box. You have just removed: Electronic serial
number, cleared data stream processors,
preprogrammed box for fresh data information
and much more.
