Trouble Checks

Warranty

Noisy stereo reception

• May be a weak station. Use AUDIO button to change STEREO/SAP

function to MONO mode instead of STEREO.

No picture, no sound but power light is on

• Maybe someone changed CABLE/AIR function to wrong position.

• Maybe a vacant channel is tuned.

• For Channels 90, 91, and 92, make sure the component

connected to those INPUT jacks is turned on in order to see

picture.

• If watching VCR (connected only through antenna input),

make sure TV is tuned to channel 3 or 4 – same as CH 3/CH 4

switch on VCR. Also check to make sure TV/VCR switch on

VCR is in correct position.

Sound okay, picture poor

• Check antenna connections.

• Try adjusting SHARPNESS function to improve weak signals.

Can’t get two channels for picture-in-picture

• One channel must come through ANT A or B connector and the

other channel must come through the INPUT 1 or 2 jacks.

• If using the VCR1 or VCR2•LD button, make sure it is programmed

to select the proper video input channel as described on page

24.

• Check position of TV/VCR switch on VCR.

• If using an S-VHS component, make sure its regular VIDEO cable

is connected to INPUT 1 VIDEO jack on TV.

No picture while using picture-in-picture, with S-VHS VCR

or camcorder

• If you have an S-VHS VCR or camcorder connected, you must

also connect a cable from the VCR’s VIDEO OUT jack to the

TV’s corresponding VIDEO INPUT 1 jack in addition to the S-VHS

cable.

Small picture does not have color

• The small picture will not have color if the large picture signal

does not have the color burst reference. All color signals and

some black-and-white signals are sent with color burst. Try

changing the channel of the big picture.

Black Box appears on the screen:
