Switching from HDMI2 watching computer back to HDMI1 to TV channels I have no picture coming on the TV. Why ?


Look if there is a FIRMWARE update for your model of TV and the SAORVIEW.

Many a times, the TV lock in with the frequency and will not release until the proper reset command arrives.

Try switching to a different resolution on the computer before you switch HDMI port

Could tv star t1020 box cause reduced vertical picture


The box may be causing this, many now have adjustments in their menu for centering and height and even width of the image.

It of course can be a problem in the set but that would show even with the box removed.

TV will not work with good remote.


Sounds like the IR pickup has gone bad or the supply voltages feeding it are opened. Sometimes cleaning the screen with windex it tends to drip inside as it follows the picture tube down into the set . Most of the time replacing the IR cures your problem. Good luck
