plays for short time and goes off

文本:

-My yamaha keyboard plays for shot time and stops to produce sound even when power is on. To make it sound a gain I had to hit one of the speakers wire on one of the transistor. That left speaker as well doesnot work. This has been disturbing for the last 2 weeks. What could be the problem and how do I fix it?
