Before Calling Service
A list of common symptoms is presented as follows. Before you call for service, perform
these simple checks. Some of these symptoms can be readily corrected. Note: Please
become familiar with the commercial features as described in TV Installation / Setup,
because the effects of several of these features, if they are not thoroughly understood,
might appear as faulty operation.
Symptom Possible Corrective Action
TV does not respond to commands (volume,
channel, power), or cannot be turned on if it is off,
or cannot be turned off if it is on.
Check commercial TV setup (TV installation /
setup) menu settings, including power forced on,
front keypad lockout, channel ring, volume
maximum features.
TV turns off by itself
TV automatically turns off after when no RF
signal is present.
Check Energy Saving Programmability setting
(see ESP) in TV installation / setup.

the mains socket. If there is still no power,
disconnect plug. Wait for 60 seconds and re-insert
plug. Switch on the TV again.

Check batteries.
Aim remote control handset directly at remote

Channel Change to digital channels is slow The first time a digital channel is tuned, the tuning
time will be slow as information embedded in the

tuning will be faster.
