Possible Remedies
1.
Check for video signal to the tuner
a.
Inspect jumper cables connecting fitness equipment to the video drop. If it is visibly damaged or
disconnected, replace or reconnect. If it passes visual inspection, swap with a known good. If TV
channel now appears, the cable is the cause. Replace the jumper cable. If the channel does not appear,
perform the same check on the F connectors.
b.
Inspect the cable that runs from the patch panel at the bottom of the machine to the console. If this is
disconnected or damaged, reconnect or replace. If the cable passes visual inspection, use a known good
cable to bypass this cable. If the TV channel appears, replace the coax cable running through the
machine.
c.
Connect the machine to a known good A/V drop. If the TV channel now appears on the console, verify
the drop is good. If not, have the customer contact their A/V service technician to repair the drop.
Getting a signal strength reading can assist in diagnosing the video problem.
2.
Verify on other machines that this is a valid channel. If a channel would appear as total snow or static (as on a
channel that is has no signal), then the console will display this as a black screen for that channel. If no
changed or something may be wrong with their head end.
a.
If the lineup has changed, rescan to pick up the correct channel lineup. If other units in the facility also
have the incorrect lineup, you will need to export this new scan information to the other units.
3.
Inspect the black USB cable running from the left side of the tuner to the USB jacks on the right side of the
console. The tuner cable must be plugged into the correct jack. If it is not plugged into the outermost jack (the
one closest to you when looking at the back of the console) plug it into the correct jack.
See Diagram 3.20.1
4.
If the signal to the console is good and the TV screen has been black for more than 5-10 minutes, then the
watchdog is not able to recover the media player. If it is less than 5 minutes or so, the watchdog may still be
trying to automatically recover the system.
a.
This can be verified by looking in the Event Log. Messages that indicate a media reboot include:
Rebooting the meda , The mediaapp restart is near, i2c timeout, or The OMAP board was rebooted
because the mpaqtapp was not running, though this is not inclusive of all possible messages.
b.
Rebooting the machine will force the media player to reboot. If the TV channel appears after rebooting,
the issue was the media player. Verify all channels and operation of unit. If the channel is still black,
then verify all other components are operational.
5.
Some older versions of software can experience a bug where only one component reverts back to a different
image. If the old image is of a much older version of software, this could cause some communications problems
between the CPA and the MFE. Open the Settings menu and select Reflashing. Check the version numbers in
the CPA Reflashing and the MFE Reflashing menus to make sure they are the correct version numbers. If they
are not or say <UNKNOWN>, then this bug may have occurred. Try rebooting the unit to see if it resolves the
issue. If not, use the appropriate Reflashing menu to boot that component to the other boot image. Verify that
the new image contains the correct software versions.
6.
If the video signal can be verified up to the tuner, connect a known good signal directly into the mini-coax on the
tuner. If the channel lineup on the console has been confirmed correct, the signal is good, the unit has been
rebooted, the software is correct on all components, and the screen is still black, the tuner has likely failed.
Replace the entire console.
