6.0 TROUBLESHOOTING
If either or both of the LM-702HD Dual 7” LCD Monitors do not appear to be functioning
properly, be certain that the source and any other device connected to the unit is
functioning correctly by connecting each device currently connected to the LM-702HD to
another monitor. (In other words, bypass the individual LM-702HD to insure that the
problem is not with the source device.) If the signal is present under those conditions,
make certain that power is present to the LM-702HD. If it is, check all cables for
damage. Cables should be undamaged, as short as possible and should be premium
quality.
Note: It is strongly recommended that you use premium cables in order to achieve
maximum distance cable runs and the best performance possible.
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 staff
be unable to assist you, contact TV One via our support website:

support team will respond within a short period of time.
