SOURCE: factory setting

Right click on your desktop and choose properties. This will take you into the display settings. Look at the adapter settings for your display driver and the RGB settings should be in there.

SOURCE: remote control codes for naxa tv model nx -524

You neglected to post the Remote's Make and Model. However, most Univ. remotes allow you to "Scan" the TV codes one at a time. You would do this and watch for the TV to turn off. when it does, you have the code and can store it.

It could be the phase control, or it could be that the governor assembly or associated spring is missing or malfunctioning.

OS or O5 Error on Landice L-Series Treadmills


Probable Cause

An OS or O5 error on the Landice L-Series treadmills, such as the L7, L8 and L9, indicates an over speed condition and this occurs when the actual speed of the running belt is faster than the set speed. The possible causes for an overspeed, OS or O5, error are: A) User weight is over 200lbs, treadmill elevation is set between 10% and 15% grade and speed is set between .5 mph and 3 mph
B) User is pushing against treadmill belt causing it to go faster than the set speed
C) Defective lower board or misaligned speed sensor
D) Maladjusted speed potentiometer

Corrective Action

A) Gravitational force will enable the user's weight to move the treadbelt faster than the set speed. The speed sensor will pick up this increase in flywheel speed and sends this information up to the display electronics. The microprocessor will then compare the actual speed to the displayed speed, determine a runaway speed condition and shut the treadmill down. An overspeed will display in the window. This is a safety feature built into all treadmills that utilize closed loop speed circuitry. The way to address an over speed condition due to gravity is have the user decrease elevation below 10% or increase the speed.

B) Similar to the gravitational force, a user can be holding onto the handrails and pushing the running belt in such a manner where they are using the treadmill like a manual machine rather than a motorized one. User needs to set speed compatible for their actual walking or jogging speed so they are not pushing the belt.

C) It's possible a blown motor control board is the problem. This occurs more frequently with PWM drives than SCR drives. However, this problem is becoming rare due to the PWM circuitry which senses this condition and shuts itself down before the drive motor receives any DC voltage at all. This means you'll get an LS or L5 error if your PWM is blown, not an OS or O5 error. This is a safety feature on all Landice home treadmills with PWM motor control boards. The SCR motor control boards also have internal protection to prevent an over speed condition from occuring due to an internal component failure. In the rarest of cases, on home treadmills, a faulty relay board can cause an OS or O5. To verify this, using a digital voltmeter, with treadmill turned on, measure the DC voltage between the V+ and P1 on the PWM board. The reading should be between 6-7 VDC. Also measure the DC voltage between P1 and P2 on the PWM board. The reading should be between 0.5 VDC and 6-7 VDC. If either of these voltages measure zero, replace the relay board.

D) Get into Open Loop Speed mode and check the speed. Adjust pots as necessary to bring up correct speed for max and min.

Repair dc motor controls on Treadmill Lifestyler mod, 831,296462


No. this happen because had been lack of maintenance LUBE. Lube the deck belt, you must do it every week of use normally. Use 100% silicones or wax instr. manual.
2) LUBE the rollerer bearings too.
3) Test the input voltage motor, if there are Voltage the motor need repari.
4) Test the output voltage board, for input voltage motor, if there are NOT the board is faulty.

Door Switch
This can cause the washer to agitate but not go into the spin cycle. You will need to remove the door switch to check it. You will perform an ohm reading on the bottom terminals. The reading varies from manufacturers most Frigidaires is around 1500 ohms others like the whirlpool duet is checked at the main control board with the door closed should be around zero ohms. You will need to refer to the tech sheet or service manual for the proper reading.

Main Control Module / CCU
The main control unit is the circuit board located behind the console. If the door switch tests good the main control is usually the problem. Check all connections for a goood tight fit. You will need to refer to the tech sheet or service manual to check this further. The main control is easy to replace.

Motor Control Module

The motor Control Module is located inside the cabinet down near the motor. This recieves the signals from the main control module then relays this information to the motor. Check all connections sometimes a communcation problem is just a loose connection. The Motor Control Module is easy to replace. To check this further you will need to refer to your tech sheet or service manual.

Belt
The belt may have come off or broke. If you hear the motor running but nothings moving the problem is likely the belt. This is easy to check and replace.

Treamill wont move with wiehg ton belt


Drive belt may not have adequate tension, motor brushes may be worn out, tread tension may be too tight, one or more of the control devices may have failed, the power to the treadmill is inadequate.

Drive belt can be viewed with the motor cover removed. If it slips, adjust tension until static belt delfection is about 1/8 inch.

If motor halts with load and belt does not slip, adjust the tread tension by turning the track tension bolts counter clockwise 1/4 turn at a time, both adjusters evenly. If no improvement 1 full turn in, check motor and or control board.

if tread adjustment does not help, check the brushes to make sure they are not hanging up in the holder. Remove the plastic caps that retain the brush inthe motor with treadmill unplugged, If they are 1/4 inch in length or shorter- replace brushes. If the motor does not have brushes, it is an AC type motor.

If brushes are fine, check motor voltage with an analog voltmeter- AC range if you have the open frame AC type of motor where you can see the windings (no brushes) and measure voltage on theboard terminals that go to motor. They should adjust from zero to at least 80 volts via the speed control knob. If the AC motor hums a great deal, replace the motor run capacitor.

If you have the DC motor, (usually about the size of a 1 liter bottle.), Check voltage range, it should have the same voltage range as above with meter set to DC range.

If in either case the motor moves fine, but full speed on control does not yield full motor speed, check the devices, usually SCR or Triacs on the AC motor type and MOSFETS or IGBT on the DC motor types.

Spin half the speed


Hi.

Depending on the make and model, and type of washer, you may need to test and eventually replace the following parts:


On top loads:


Variable speed motor .
Motor coupler.
Transmission.
Control board.
Motor control unit (if present)


On front load :


Variable speed motor .
Motor coupler.
Control board.
Motor control unit.


On top load the problem is often transmission or variable speed motor. On front load MCU or motor.

MAH 2400 AWW flashing error code "dc"


Hi Pepsi,
"dc" means that the control board is trying to ramp up (that is, send a signal to the motor controller), but has encountered an unbalanced load and so shuts down. Specifically, "dc" means "distribute clothes".

I took this opportunity to upload a Tech and Troubleshooting manual for you. Here is the link for it. Read it carefully. You will be required to perform a "board output" test after placing the machine in "Service Mode".

I gotta tell ya, though. Based on my history with these, I highly suspect that the machine control board has failed. Let me know what you find, OK?

(And don't forget to rate this solution as "FixYA!", deal?
