ACCESSING THE PLAYFIELD
On newer models of Let’s Bounce the underside of the playfield is split into three panels, allowing
easy access to the bottom of the playfield for maintenance purposes.
If your unit doesn’t have three visible panels underneath it, please disregard this section.

35
 1. Identify the panel you want to remove and remove 4 x M4 x10 screws and washers per
panel, as shown below

2. After removing the screws, follow the sequence below – lift, pull, then tilt – to remove the
panel

PARTS DESCRIPTION
HEADER DISPLAY
The header is a static sign illuminated by LED strip lighting.

BACKBOARD
The backboard at the rear of the game mounts the speakers, FB63 timer display, FB44 score displays,
and LED strip lamps. All components are accessible by removing the guards behind the backboard.

SPEAKERS
Two component speakers are wired to the left and right outputs from the FB106 sound board. Each
speaker pair consists of a crossover, woofer speaker and tweeter speaker.

PLAYFIELD
CAUTION: Take care when working around the playfield tiles and ensure mounting
mechanism is not damaged.

The playfield consists of 45 tiles. Each tile is a delicate assembly containing one FB205 Sensor PCB.
The FB205 is a sensitive PCB used to detect the vibration caused by a ping-pong ball hit. Extra care
should be taken when handing and cleaning so as not to damage the mounting.
Each FB205 is programmed with firmware and communicates with the FB216 using an RS485 data
bus. Ensure DIP switches on each FB205 are set so that each PCB has a unique address as defined in
the image below. Correct addressing is critical and starts as 1 and increases to 45 from left to right
and from front to back.

37
DIP SWITCH ADDRESSING
Addresses are set via DIP switches using binary coding. Patterns are shown below:
Do not use address 0.

COUNTERS
Counters will increment for each coin inserted and each ticket paid out. Counters are under
firmware control and are not directly connected to the mechanisms.

BUTTONS
Press the green SERVICE/BACK button to issue a service credit from attract mode. Press and hold the
green SERVICE/BACK button to enter temporary Free Play Mode. This will remain in place until
machine power is reset.
Press the red TEST/ENTER button to enter the operator menu from attract mode.
When in the operator menu, use four up/down/left/right buttons to navigate through the menu.

VOLUME KNOB
Use to adjust the speaker’s sound level.

COIN MECHANISM / BILL ACCEPTOR / CARD SYSTEM

Credits can be inserted via a coin mech, bill acceptor and/or card system connection. All interfaces
are located inside the front coin doors.

TICKET MECHS
Tickets won are paid out from two ticket mechs. Being a 2-player game, tickets are paid out on the
mech corresponding to the player. Player 1 tickets are paid out on ticket mech 1 and player 2 tickets
are paid out on ticket mech 2. The exception being when the “Card System” game setting is set to
ON. If a 2-player game is played by crediting only a single player position then all tickets are paid out
on that players ticket mech.

PLAYFIELD FUSES – FB214

Each tile on the playfield receives an independent power and data connection. Each tile is fused by
the FB214 PCBs which are located behind the side panel.

GAME BOARD – FB216

The FB216 is the main control board for the game. It contains the application firmware and output
drivers to control the lamps, displays and tiles.

SOUND BOARD – FB106

The FB106 is the sound driver board containing the sound files and amplifier. Volume is adjusted by
the potentiometer on the operator panel.

BALL DISPENSER
The ball dispenser is a 2-stage mechanism consisting of a ball lifter and a ball gate.
The lifter is a rotating plate to lift the ball to the ball gate. Balls are counted by the FB84 IR Sensor
PCB.
The ball gate is used to hold the balls before dispensing them to the player. Gate position is detected
by the FB165 sensor PCB.

39
POWER INLET/MAINS SWITCH
The power inlet is a standard IEC inlet socket with a mains power switch, located at the rear of the
machine. There is a main power fuse internal in this IEC socket. The fuse should be a M205, 250VAC,
8A.

WARNING: ALWAYS turn OFF mains power and unplug the game before replacing any
fuses.
ALWAYS use the correctly rated fuse.

POWER SUPPLY
The machine is powered by a 600W 12V power supply. AC input is universal 85-265VAC 47-63Hz.

LAMPS
WARNING: Always turn OFF mains power and unplug the game, before replacing any
lamps.
Always replace the lamps with the same or equivalent size, wattage and
voltage.

All button lamps are 12VDC T10 LED or equivalent.

All Playfield tile lights are FB205 PCBs.
All remaining lighting is RGB LED strip.
Contact your nearest LAI Games office for replacement LED strip to ensure color is matched.

MAINTENANCE
EXTERIOR
• Regularly dust and clean the external cabinet areas as required, using a soft water-damp
cloth and mild soap.
• Check for blown bulbs and replace as required.
• Check all LED strips are functioning and repair as required.
• Check that all playfield tiles are operating and positioned correctly. Tiles should all be at the
same level, orientation, and spacing.
• Check all foam padding on the playfield cross-beam mounts is intact with no exposed metal.
Re-glue any foam that has come loose
• Check below the playfield for stuck balls, clear out any obstructions to allow balls to roll
freely.
INTERIOR
• Regularly dust and vacuum the interior of the cabinet, taking care to remove any objects
that may have fallen.
• Check and tighten all fixing hardware and fasteners as required.
• Check the ball dispenser sensors are clear, blow out any dust from the optical sensors.
• Check the ball lifter is free to rotate and balls are free from obstruction.
• Check the balls are clean and undamaged. Discard any balls that are cracked or deformed.
