Poor Quality Video - One Channel or Limited Channels
Description
One or a limited number channels on a unit has poor reception or no reception.
Possible Causes
1 Loose or damaged coaxial cable.
2 Poor television signal to the machine.
3 Incorrect channel scan lineup.
Possible Remedies
1 Check for good video signal to the tuner.
2 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 the 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.
3 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.
4 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.
5 Verify signal strength with signal meter.
6 As above, verify condition and connections of coax cables as well as verify quality of signal to that
drop. Verify signal strength using a signal meter.
7 Rescan channels on that unit. This is less likely to be the problem if the channel is coming in poorly
since if the console is looking at the wrong channel number entirely, this should manifest as a black TV
screen rather than poor video quality.
