Question about Sport & Outdoor - Others

Open Question

Hi, I've purchased and have just completed the assembly of a Schwinn 840 treadmill. After powering up the unit, the screen shows a message stating "Safety Key / Lock Out." When pressing buttons on the console, I hear beeps but nothing happens. Have tried recycling power to the unit with no effect. Grateful for any support that can be provided to get the treadmill out of this "lock out" mode.

SOURCE: Inspiron 530S Power Save Mode Loop

First you need to make sure that there are no other removable devices plug on the system, like usb, external hard drives, then if that will work try to go to the bios, press f2 when you see the dell logo, and go to the system setup, go to the boot device configuration and make sure that removable device is not the first boot device, if it is the first one choose hard disk and then second boot device ad cd rom/dvd rom and then disable the 3rd boot and the fourth boot device. Make sure to save the changes. And restart the system again. Once the computer is back and running try to go to and check the bios, download if there is a bios update for the system.

SOURCE: Blank Screen

First, confirm that it is the screen itself. Connect the video output to a known working monitor and then power on your Thinkpad. if the known working monitor behaves the same way you can rule out the laptop's monitor as the source of the problem. This may be the BGA, Ball Grid Assembly, leadless soldering problem related to video chips on the motherboard, but first test the monitors.

SOURCE: wont turn on... balck screen

Hi, I just learned here that you have to do TWO things to get it to turn on. One, make sure the slider is in the On position. Then press and hold the play button (top one on the wheel) for 3 seconds. Worked for me, when previously the only way I could get it to turn on was to hook it up to a power source (wall or USB), which sounds slightly different than you. Hope it works anyway!

SOURCE: My grandson was using the

It is possible that the electric motor that moves the incline has gotten jammed from the continuous pushing of the up button. These inclines have limit switches on them. To stop the motor from running in these situations. It also has a limit switch on the bottom to stop it from going too far down. You can check this switch to make sure that it is not making. Or the lower switch could be malfunctioning. This would not let the incline come back down. You also might try to unplug the treadmill over night and see if the electronics will reset. I hope that this helps you!

After using the a40 only a few times, the pedal crank assembly shifted to the left so that the crank arm on the left side scrapes against the plastic casing.

E-2 message on schwin 420

You may be able to reset the main board by detaching the ribbon connector, then reattaching it. Unscrew the four screws that hold the display panel, and you will see a ribbon connector and a round connector. Gently squeeze the tab in the center of the ribbon connector and pull it off. Wait a couple of minutes, then reattach the connector by gently pushing it into the socket. The display should show a boot-up process and then the normal blank screen with the prompt to select user. If the E2 error returns, repeat the process. If this procedure does not reset the board, you will need to contact Schwinn about possibly replacing the board. You can contact them by going to ( and select the "email us" link or call the 800 number.

Schwinn 820 treadmill quit working in the middle of walk shows L-5 on screen. what is problem?

Loss signal: 3 possible areas that can be causing the problem speed sensor , motor control Board ( MCB ) or the drive motor. Unplug unit remove motor shroud then plug in unit now on the MCB their should be L E D s lights should be on. One of the L E D s should speed on other P W M . Start your treadmill you see the PWM light flickering thus the upper console and cable connections are good now it will go back L S. Reset your treadmill then manually start pushing the running belt now the speed light should be flickering if it does then the peed sensor is good if not flickering then replace sensor. If we have a good speed sensor then I would check the Drive Motor this done unplugging the unit the disconnect the two leads coming from the motor to MCB then by using a fully charge 18v drill battery connecting the leads to the motor should move it at approx; 1 mph then Your MCB is defective and need to be replaced. if no belt movement you for the most part will have worn brushes or open windings in the motor , I would open the brush compartment and inspect the brushes if they are less than 3/8" in length replace them this should the motor issue. Good Luck
