Hi everyone I have a home audio video system of Samsung company. Now it is not working properly. The picture is seen first, then the sound is heard, and sound quality is also not correct. When I increase the volume it gets decreased and vice versa. I do not know where is the main problem as I do not know anything technical about audio video systems. It is no longer under warranty. I want to repair it on my own. Please tell me how to repair this problem in steps as soon as possible.
