Question about Sansui Televison & Video
After a few minutes when I turn the tv on, it changes the source to tv channnel1. then I try to press the source button to return to hdmi or video and it is like someone is holding the down button, so it goes by itself on all the sources. if I press ok on one of them as it goes down automatically then I returns after a second to source tv channel 1.

SOURCE: TV changes channels itself
Have you checked to see if any of the front panel buttons are depressed and stuck??? this is a big problem these days?? I have also found the infared remote sensor to be bad on some sets that do crazy things all by them selfs.. A funny storry once i had was a customer called me after her mother called some goast finders as her maggy projection set would go on all by itself andf the channels would change and the volume would go up and down all by its self. funny thing I had a set just like thast in the shop at the time with the same problem and I scoped out the output pulse from the infared reciver on the set and that was putting out noise on the data line and caused the set to eratacly do all sorts of weird stuff. get the point?? its a stck button or the remote sensor is bad.

first place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

you will have to program the tv to cable for it to work then it should start changing the channels and if that doesn't work then you might have a bigger problem with the tv

Usually sets that are "possessed" in this way have defective "tact" switches. Replace all switches and that should take care of the problem.
