What channel is it and when they tune in that channel, is the picture nice and clear or is it grainy and snowy before the screen goes blue? On some sets, if the signal is weak, the picture will go blue. This is called Blue Screen and is there so you do not see very poor, grainy and snowy pictures. Some sets will have an option in the menu to turn the blue screen off.

Tv won't change from chanel to chanel

Do a hard reset to this set and check first. To make it hard reset, unplug the set from AC mains wall socket, and re-plug it back after 10 minutes or so.If this do not help you, check and replace its main system memory IC.

Audio and Video Front Inputs are available

for a quick connection of a VCR, to playback

video from a camera or attach a gaming

to tune these inputs.

(or accessory device) to the Video (yellow)

Input located on the FRONT of

the TV.

2 For Stereo Devices: Connect the audio

cable (red and white) from the Audio

Left and Right Outputs on the Camera

to a Stereo to Mono adapter. Then plug

the single end of the adapter to the

Audio In (white) jack on the FRONT

of the television.

For Mono Devices: Connect one end

of the audio cable from the Audio Out

jack on the device to the Audio In
(white) jack on the FRONT of the television

3 Turn the TV and the accessory device


4 Press the AV button on the remote

control to tune the TV to the side input

jacks. "Front" will appear on the TV


5 Press the PLAY  button on the

accessory device to view playback, or

to access the accessory device (camera,

Repeatedly pressing the AV button on the

If it is it could have a dry joint on it or perhaps dirt in it. You can clean it with Servisol switch cleaner.
