Troubleshooting

If the TV does not operate as usual or appears to be faulty please read carefully this section. Many
operational issues can be resolved by users.
It is also advisable to unplug the TV form the AC socket on the wall for 60 seconds or more, then reconnect
and start again. This simple procedure helps in restoring stable conditions for electric circuits and firmware of
the unit.
Please contact Manufacturer Customer Care if the problem is unresolved or you have other concerns.

An electrical appliance may be affecting TV set. Turn off any

Insert the power plug of the TV set into another power outlet.
If using an external antenna, check the direction, position and
connection of the antenna.
Adjust the direction of your antenna or reset or fine tune the
channel.

"Click" sound can be caused when the temperature of the television

contract, which makes the sound. This is normal and the TV is OK.
