UNIT DOES NOT POWER UP. I CHANGED THE POWER BOARD WITH NO RESULTS. POWER BOARD 120 VOLT LIGHT IS ON. 9 VOLT DC LIGHT IS ON. PWM & TACH LIGHTS ARE NOT LIT. CONSOL DOES NOT LIGHT UP

The power supply board has gone bad.It would be more cheaper and easier to buy a new TV than to try and fix the TV that is not working.

CAMMERA DESTROYED !! MOTION LIGHTS USE 120 VOLT AC POWER
CAMERAS USE 12 VOLT DC POWER

WRONG TYPE AND AMOUNT OF POWER !!!

The SCR lower board is designed with diagnostic LED lights. The LED's are color coded according to
their specific function. Green indicates a properly operating treadmill; the green lights should always
be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a
treadmill malfunction. Here is a list of each LED and what it signifies:
MOTOR (yellow) - The MOTOR LED illuminates when dc (direct current) voltage is sent to the drive
motor. The LED gets brighter when the dc output is increased.
RLC (yellow) - The RLC (R = Reactance / L = Inductance / C = Capacitance) LED illuminates when
the filtering system is properly working. The filtering system includes the capacitor and filter choke. If
there is a short in either component then the RLC light will not come on.
DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are
functioning properly. When the LED lights, it tells us that the relay has energized and is sending high
voltage (110vac or 220vac) to the elevation motor.
AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is
delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR
LED.
+12V (green) - When the proper AC voltage is delivered to the treadmill, passes through the in-line
fuse/s, through the full wave bridge rectifier (changes AC to DC), through the transformer (steps down
DC to +12vdc) then the +12V LED lights.
This the board LED, who control the signal for Main Motor+Elevation Motor. You must see, the LED DN+ UP( both will be Lit) in any position down or Up.
2) The RELAY board is designed with diagnostic LED lights. The LED's are color coded according to
their specific function. Green indicates a properly operating treadmill; the green lights should always
be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a
treadmill malfunction. Here is a list of each LED and what it signifies:
AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is
delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR
LED.
VDC (green) - The VDC LED will light when it receives DC voltage from the DC power supply.
DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are
functioning properly. When the LED lights, it tells us that the relay has energized and is sending high
voltage (110vac or 220vac) to the elevation motor.
UPSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display
board to the elevation UP relay. This low voltage dc is what energizes the coil of the relay.
DNSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display
board to the elevation DOWN relay. This low voltage dc is what energizes the coil of the relay.
BELTSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper
display board to the belt (motor start) relay. This low voltage dc is what energizes the coil of the relay.
SPD (yellow) - The SPD LED flashes on and off (relative to speed) when the speed sensor is
operating properly.
PWM (yellow) - This LED will light when the upper board is sending a speed signal to the PWM.
Both the PWM LED and BELTSW LED must be lit for belt movement.
Finally this this Relay Board, the Each Led will be Lit, for any Relai control for DN down, or UP elevation motor. Use the contact cleaner, you can find it in R .Shack.

With this you must fix it.

Double check your brush istallation. positive side toward rotor bearing, if you put 12 vdc directly into brush pack and check with a meter at the 120 vac outlet and have low or no voltage, you may have no resistance in your rotor slip rings, excitor & main windings also need a resistance check. 12.6-16.7 ohms (rotor) 2.26-2.80 ohms (excitation) .26-.32/.28-.35 main or power windings. Note: unit running when appling 12 volts to brush pack. 2-5 second only, ( This test tells you the rotor & stotor are ok )

I think you should check the real power supply ... 120 V in and what comes out ... volts (ac - dc) and amps or what fraction of an amp.

Please compare the old with the new power supply. The new power supply should be the same volts - same kind (AC or DC) and at least the same amp rating. You can use higher amp rating but not lower - lower will burn up - literally)

Volt meter ... always set it above the suspected voltage. Batteries are always DC. Houses, buildings, etc always AC. Power supplies - could be mixed - ac in and dc out.

So if you were measuring in your home, you set the meter to 130 or higher on the AC scale. If you were doing your auto, 24 volts DC (or so).

House current, probe color doesnt make any difference. Should read about 120 Volts between the narrower (or right side/ground down orientation) or the two slots and the wider of the two shots (wide should be the neutral side - ground on the bottom). You can prove the hot side by measuring to the ground. White wire to ground = no reading. Black wire to ground = 120 volts. (The black and white are INSIDE the electric outlet. You can use either probe to do the measurement.

I hope this helps you.

If you have more question, please let me know.

it is two items in this case. The light on the PWM will light if you force the belt to move. I would start with a lower board replacement. If it works fine then you need a new console. I have seen this when people use the heart touch bars on the treadmill and get a static shock. this can ruin the console.

Vacuum works with the battery but does not work with 120 volt. Every time I plug it in it blows the internal fuse. I have replaced the fuse inside the vaccum several times and every time i plug it in it blows. What do you think it could be?
