I need to pass on the backlog list with these games, rebuilds and purchases. I guess the lockdown and stim checks has everyone playing board games again. The eBay item you purchased has a 30 day handling time from the purchase date before shipment. That is the maximum eBay can set it at.  The way it looks that might be close to 8-10 weeks before actual shipment from the date of purchase.  Games, rebuilds and repairs are shipping almost daily.  I’m working 24/7 on these but the backlog is out there.  If you are ok with that, make the purchase. That will put your purchased item in the shipment queue from the purchase date. Thanks for understanding.
This is a repair service eBay item.
You need
to send in your broken tower for this repair or restoration.  Please send tracking information as soon as possible.  I do not have cover for weather at my front door.  So I need the tracking info to watch out for your package.
The eBay shipment delivery time is set at 30 days.   This will allow enough time, for the tower to be received, repaired and returned back to you to stay in compliance with the eBay shipment delivery time.
The Summary of This Repair Service
covers,
replacing the carousel motor
with a minty fresh motor which includes
adjusting the carousel LEDs
for correct picture alignment, cleaning the
keypad connections,
restoring the keypad label from spots, cleaning of all moving parts and
replacing old lubricants
.  Also included is cleaning and
polishing the battery contacts when possible,
removing the battery
compartment wires
and inspecting for damage and re-tinned.  Disassembling the
power switch
for cleaning with new switch lubricant added.  Cleaning the
case parts
inside and out.  Adding quick revision updates to the
circuit boards
that don’t involve component replacement.  Replacing both of the original
electrolytic capacitors
with NOS components.
After receiving the tower,
there will be a follow up message after an initial inspection to discuss the repair options if needed.  Other parts and repair time costs
may be needed.  But the point of this
‘all inclusive’ repair process
was to cover all of the most common issues in one package.  These electronic towers were issued in (8) different circuit board versions that can have a whole host of age, revision and battery corrosion related problems. Versions part numbers on the back of the board are:
7924149
001, A01, A03, B03, D01, D02, E01, E02.
The New Motors
are much quieter and spin the carousel pictures slightly faster.  That will be a huge bonus at speeding up your game on every players turn.  There has been very little, long term success, with cleaning the original motors. Even after a thorough cleaning, these old motors aren’t guaranteed to be reliable.  The original motors seem to fail or run slowly after the Dark Tower game has been put away in storage for a while.
After the updates,
repairs and cleaning have been completed, your Dark Tower will power on and complete the carousel self test and work perfectly on every turn with correct picture alignment!
Please pack the tower very well.  Some have arrived damaged from too small of a box.
Use a large enough box with plenty of room to clear all sides and lots of packing material.
There are sensitive, pins between the tower cases and Merlon tips around the castle top.

ore detailed repair information.
A Correct Dark Tower Power On Self Test consists of
installing batteries in the correct direction, power switch on, a number
ZERO
digit will be displayed in the left digit for 1 secs, then 2 red flashing dashes (–) in the display window.  The tower waits for any key on the keypad to be pressed to initiate the Self Test.  Once any key is pressed, the tower display will go blank, then it will begin the self test . The motor will power up and spin the picture carousel to the open test section.  Then, the digits
88
are displayed in the digital display window as the 3 light bulbs are being tested one at a time, from top to bottom, with an accompanied speaker beep.  The self-test is complete when a flashing
L1
is displayed.  See the paragraph below for failure details.
Level 1 – 4 and Players 1 – 4
can then be selected using the keypad.  Refer to the Dark Tower instruction manual under Chapter (3) Steps (1 & 2), pages 5 & 6.

Common Tower Power On Failures:
The tower powers on with a left digit zero then 2 flashing dashes (–).
When you press a key to initiate the self test and the display goes blank and nothing happens.  The carousel does not spin and the tower does nothing else.  The most common fault is the carousel motor failing and it needs to be cleaned or replaced.  Replacing the motor is the best remedy for long term reliability.  The new motors are extremely reliable and operate very quietly in comparison.  Cleaning the original motors can be performed, but may fail again after the tower has been sitting unused for a while.
The
tower will power on, left digit shows zero, then 2 flashing dashes (–).
You press any key on the keypad and nothing happens and the display still shows 2 flashing dashes.  That means the keypad is failing.  It needs to be cleaned or repaired as a keypad wire trace may be broken disabling one or more keypad buttons.  This item is here for just the keypad repair. http://www.ebay.com/itm/223811278905
On Power On, the tower may show a number 8 in the left digit or a number 0 in the right digit.
The tower carousel with power up with
erratic behavior
.  It may or may not spin with dim lights without having ever having to touch the keypad.  You may have to power off, pause for recommended 10 seconds, then power back on. Sometimes this works and sometimes it takes a few attempts for the tower to complete a self test.   This very annoying
Power On
problem is related to the circuit boards that were released early in the games production or your batteries are too weak.  These circuit boards need
wiring and component updates
for reliable operation.
This problem is actually mentioned as a workaround in the
Dark Tower Game Instruction Manual
under Chapter (3) Steps (1 & 2) pages 5 and 6.  Here is the
Warning
in the instruction booklet.
IMPORTANT — WHAT TO DO IF THE TOWER TEST FAILS
If your tower did not emit the above signals in the order described,
it is not functioning properly.  Try the test again but be sure to wait at least 10
seconds before turning the unit back on again.
ALWAYS OBEY THE FOLLOWING CAUTION —
WHEN TURNING
THE TOWER OFF,
WAIT AT LEAST TEN SECONDS BEFORE
TURNING IT BACK ON TO AVOID MALFUNCTIONING!

problem.
Symptoms include:
The tower may eventually power on, but you might have to turn it off, pause 10 secs.,  and back on a number of times to get the tower to finally complete the
self-test.
This problem is actually mentioned as a workaround in the
Dark Tower Game Instruction Manual
under Chapter (3) Steps (1 & 2) pages 5 and 6.

Circuit Board Updates
related to this problem can result in
$15
in additional parts.
These major updates were included with the later released
D01, D02
and
E01, E02
Version
circuit boards.  The Dark Tower circuit boards with version
D01
,
D02
and
E01, E02
will still need a small circuit update that’s included in the initial auction.
All circuit board components are checked for age related issues.
The electrolytic
capacitors are now replaced as part of the service.
LED Digit Display Replacement or Upgrade:
If your display is missing one of the lines(segments) the display can be replaced with a
new custom built display
. The new displays are very bright and can be seen in a bright room with no problem.  These new, brighter displays are available in
original sized
.36″ or l
arger
.56″
at $25
.  Pictures of the display size comparison can be seen here.

Keypad Repairs.
The aging keypads are finally dying out from oxidation.
Have it restored to better than new condition.  Your keypad is carefully disassembled and cleaned.  New foil traces are added to restore functionality.  Then, reassembled and fully tested for reliable operation.  The keypad restoration adds a
new, very light touch in pressing each key.
No more having to
dig in a fingernail
to press a key.
This is not a keypad replacement with other keypad parts off eBay.  This restoration reuses all original parts at an additional
$25
.
*** NEW UPDATES *** The keypad label is now cleaned of the annoying spots as part of the rebuild.  Look at the 2nd picture to see the difference.
Replacement Front Lens.
A custom replacement part is available for your Dark Tower if yours is missing the front lens.   This front lens part uses the same bottom slot in the case and pin at the top like the the original lens does.
Each front lens part is hand made using smoked Lexan that is custom bent to fit the curve in the front.   On the inside of the lens, it has black tape applied to create the viewing area similar to the original lens at
$25.
Battery Compartment Corrosion.
If the metal contacts are corroded to a point that they need removal and the zinc plating is still usable, reconditioning will be needed by removing and polishing for
$25
.  If the zinc is corroded beyond polishing and the base steel metal is still usable, the contacts will be removed cleaned, sandblasted, filled with silver solder if needed, then zinc/tin electroplated with a blue chromate dip for an
$25
.  With the final option being, where the base metal of the battery contacts are too damaged they are replaced with custom stainless steel contacts at
$25
.   The orange corrosion is cleaned up as bestest as possible.
The Battery Compartment Power Switches
are always disassembled and cleaned for reliable operation.  New switch lubricant is added.  The switch contacts are another factor in glitchy power problems from oxidation.
New Battery Compartment Power Cables and Connectors
may need to be replaced in battery corrosion towers at an additional
$10.
The speaker/motor connector with wires at
$5
.
Carousel Picture Cell Alignment
is always checked. The alignment LEDS are adjusted on each tower.  Units with revision circuit board updates or new motor replacement are custom installed and adjusted.
Carousel Motors
are removed and replaced with a new motor.  The old motors are being replaced as a standard procedure.  The original motors are an old design that are very unbalanced.  This unbalance creates a noticeable vibration when the carousel turns and is easily heard.  The newly designed, replacement motors with new wiring are installed.  The new motors operate at
slightly faster
than original motor speed and are
super quiet
as the carousel turns.
Tower Case Pins
replacement is available. These 4 pins keeps the outer case in place so the carousel doesn’t rub against it. This also keeps the front lens in place so it stops falling off.  Replacing the pins are an additional
$10.  The Tower cap pins are replaced when needed for $5.
PCB Foil Repairs
Heavy
potassium hydroxide
and related gases
can permeate the tower case from severely depleted batteries left in the tower.  These gases destroy the PCB traces and coat and oxidize exposed metal. These dark spots can be seen behind the green PCB masking and no longer make any contact at those locations.  Basically, the corrosion has dissolved the metal in the PCB foils and cut traces causing the tower to fail.  These damaged PCB traces appear bubbly and darker underneath the green masking.  This happens from leaving the tower powered on while the batteries drain and then leak and the gases cause corrosion damage.  These damaged traces are repaired and reinforced with wire strands or
Soder-Wick
as a permanent and durable repair.
Pricing will vary based on work needed.
Please pack the tower very, very well!  Some have arrived damaged from too small of a box.
Use a large enough box with plenty of room to clear all sides and lots of packing material.
There are sensitive pins between the tower cases and the merlon tips on the top.
