My original remote is not working. I bought a universal remote and it doesn't work either. Can't get a remote to work on the tv


Hello
The remote sensor inside the circuit board of your TV is faulty. It is the component that receives the infrared signals of the remote control. If this component go faulty, no remote control will go with the TV. This component can be located on the front panel board of the TV just behind the infrared sensor window at the front. You have to open your TV to locate this component. It is a three terminal component, look brownish black in colour. The sample picture of it has attached here. It is very cheap to buy, and can be bought from most of the electronic sparepart shops at your town. If you have a concept of soldering and resoldering, you can replace this component yourself at home OK.

Tv picture is getting too big for the screen. Can the picture size be reduced?


Hi, well this is most likely a Aspect Ratio issue, this can be set via the TV's Menu. You simply need to adjust this aspect ratio, to suit you viewing requirements.
It is all explained how to do this in your user manual, link provided below. http://www.devicemanuals.com/guide/Television/Symphonic/Symphonic-ST420FF-20-TV-Owner's-Manual-T0RVek16az.html
