6.0 TROUBLESHOOTING
Aside from faulty AC or DC power, most problems with the 1T-MX-3344 relate to
damaged/poor quality cables or incorrect signal levels.
If some inputs function correctly and others do not, interchange cables between sources
and see if the problem moves with the cables. If it moves, a bad cable or cable
connector is the probable reason for the trouble. If the problem remains with one
particular input, connect that source to a different input using the same cable and see if
the problem moves. If it does, the problem is with the source.
After trying the above suggestions should the problem still persist, contact your dealer
for additional suggestions before contacting TV One. Should the dealer’s technical
