Min Yamaha rx-v1500 surround reciever er delvist stået af. Den slukker efter få sekunder. Købt i 2005.

Jeghar googlet mig til at det nok er det her som er galt:
"The audio output transistors are mounted to a large heatsink which keeps them cool during operation. They are electrically isolated from touching the heatsink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise; as the heat goes up they conduct more current and cause the protection system to activate and shut the set down (in order to avoid damage to the set)"
Det er formentlig billigt at reparere den, hvis man ved hvordan, men jeg kan ikke.
