Question about SansuiM1315 TV

1 Answer

TV Will not fire up.

The set, a Sansui Colour TV, Model No SV2918 -74cm, was working fine until ,the top right hand corner of the screen pulled in and caused a distorted picture about 10cm inwardly.About half an hour later the set suddenly blacked out. I replaced the the horizontal output transistor and switched the set on. No raster/no sound ,static felt on screen and nothing else.When the set is switched bsck on again, pilot light comes on for a fraction of a second and dies out.No raster/ no sound, but a faint hum is heard through the loud speakers, no static on the screen. I replaced IC 801, MC44608 being the power supply still nothing. Please can you help me? Thank you.

Don't know the model from the information you give, so can only give general advice, but you can try looking for OSD or On Screen Display or On Screen settings on the TV's menu.

i need more info?
The video1 is the input channel ,the auto is the sound and video system the tv uses to identify the signal(you have a multi system tv) {multi system (pal,ntsc,secam etc) if it is in auto mode you dont need to worry about it , the tv wil identify the system automaticaly and set the apropriate setings by itself.

You could press av on tv or on remote to switch between av1 /av2 /tv program etc, make sure the ant / dvd / cable etc is conected and on while selecting / pressing av button.
