ENTERTAINMENT TROUBLESHOOTING
Verify that your TV is Matrix brand equipment. Compare your TV to the TVs in Figures A and B. Compare your controller to Figure C. If your equipment looks different contact Matrix or the manufacturer of your TV equipment if known.
For Matrix produced and mounted equipment you can use the information outlined in this section to help with any connection and power issues you may have. If you have questions that are specific to the TV alone (settings, programming, menu options, etc) please see the entertainment owner’s manual.
PICTURE FUZZY OR UNCLEAR
Using a verified good piece of coax cable, remove the console back cover and hook the coax directly to the TV jack.  This bypasses internal connections for your machine.
Check your internal cables and fittings inside your machine at the console and below the motor cover. Make sure you have no damage (kinks, cuts etc) and no stray wires or poor fittings on the ends of the cables. Fittings should look clean  connector and no stray aluminium strands touching the centre conductor. Replace or repair any suspected cables.
If no damage can be found on cables, fittings, or connectors begin replacing cables and connectors with known good parts until the damaged part is found.
TV WILL NOT TURN ON
If you have no picture at all, check to see if you have any status lights on your controller (controller light is next to power button).  The status light should be red when off or in standby mode, and green when the TV is powered on.
Remove the console back (Figure A) and check the electrical connections for the TV
After you have verified all connections are secure and problem still exists verify power at the outlet. If outlet is not outputting 120 volts, check  room power.
If internal electrical connections are good,, and the outlet is outputting 120 Volts, the issue is likely with the TV, contact Matrix.
CONTROLLER ISSUES
If you have a status light on the controller but the On/Off button gives no response, disconnect and then reconnect the power to the treadmill from the wall. Attempt to turn on the TV again using the On/Off button.
If TV still does not power on, remove the console back  and check the controller connections at the console.
If the TV does not power on after the controller connections are reset, the issue it is likely with the TV itself, contact Matrix.
