Troubleshooting 3.22- P80 Poor Quality Video Single Unit Only
Description
Television signal is present, but picture quality is consistently or inconsistently poor across all available channels.
Possible Causes
1.
Loose or damaged coaxial cable
2.
Poor television signal to the machine
3.
Incorrect region setting in channel settings
Possible Remedies
1.
Check for good video signal to the tuner.
a.
Inspect jumper cable 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 jumper cable.
If a 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.
d.
Verify signal strength with signal meter.
2.
As above, verify condition and connections of coax cables as well as verify quality of signal to that drop. Verify
signal strength with signal meter.
3.
Enter the Settings Menu. Select System Settings, then TV Settings. Verify that unit is set for United States.
