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.
6
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.
7
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.
8
Verify signal strength with signal meter.
9
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.
10
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.
