Yamaha RX V465 turns of after few seconds

[hemant_2222]

Hi All,

This is my second unit that i have taken for repair.

The first one was also yamaha and was repaired with help of Mark, Z ( if i am not wrong )

Now, coming to this unit,

The first place i checked was for the DC offset at the output and there is approx. 2.5 to 5.0 volts at the middle pin of emitter resistor.

Also, the supply to both the STKs are +/- 24 volts instead of +/- 50v, as per the schematic. Is this the place to start with.

Please assist.

Regards,
Hemant.
