Possible Display Issues

eSpinner Models 7140 and 7200

A. Touch Screen related issues

Symptom: The touch screen does not recognize a touch on the screen or the touch points are out of alignment.
Troubleshooting:

I. Clean the surface of the screen with a damp cloth (do not use a cleaning agent that contains ammonium

and do not spray directly onto the display) to get rid of any kind of settlement. Also pay attention if there is
anything stuck between the plastic front cover and the actual touch screen.

II. If you can access the service menu using the touch screen, select the button that says “recalibrate” while

in the “Calibration and Setup” menu (Fig.1) to start the touch screen calibration process.

Fig. 1

III. If you can NOT access the service menu using the touch screen follow the instructions in document

number 637-1004 and try to recalibrate the touch screen this way. It might take some tries before this
works. Be patient and use a stopwatch for this procedure. You have to be very precise.

B. Power related issues (black screen).

Symptom: The complete screen does not turn on and stays black (Fig. 2).
Troubleshooting:

I. Remove the display and post and disconnect the power connector. Measure if you get 12V out of the red

and black cable that routs through the neck.

II. If you do not get 12V check the cabling for damage and see if the green light on the power supply (hidden

in the base of the front section of the frame) is lit.

III. Check the cable that routes into the display (black and red) and plugs into the mother board if there is any

damage and check for continuity.

IV. Verify that the connector inside the neck itself is making a solid connection. Bend the pins inside the

connector if needed to ensure a solid connection and proper power flow. Perform a vibration test (snap
your finger a couple of times onto the connector while the unit is turned on) to see if the connection is
solid and won’t fail later on when the unit is reassembled again.

Parts reference: 740-6971 Main Power Cable (red and black cable that connects to the mother board on one end
and to the power cable that comes up from the power supply in the base of the unit).
740-6985 Internal Power Supply (the red and black cable inside the neck that connects to the
power cable coming out of the display is hard wired into the internal power supply).

C. RPM related issues (Cadence)

Symptom: The unit goes over into the cool down mode after three minutes because it does not recognize

any movement on the pedals. Also see document number 635-4149.

Troubleshooting:

I. Align the sensor and check if it points in the right direction and/or bring it closer to the flywheel (Fig. 3).

II. Check the continuity on the sensor and extension cable (opens and closes the circuit when the

magnet comes by).

III. Check if you get RPMs on the display (go into the video model/Instructor mode on the screen,

disconnect the sensor connection inside the neck and quickly tap/shorten the two pins inside the
connector a couple of times to simulate a signal).

Parts reference: 740-6987 RPM Sensor, 740-6986 RPM Extension Cable (connects to the RPM sensor on one
end and to the RPM cable that comes out of the display), 740-6964 Display RPM cable
(connects to the RPM extension cable on one end and to the display mother board).
