Question about Yamaha RX-V2400 Receiver
I was wondering if you can tell me why the receiver turns off after 2-3 seconds, just at the time that the volume is expected to come on.
Thanks for your help. any solutions?
there are several reasons, but the most common is because a high power trasistor is shorted, most yamaha receivers use the same names for the failure signals, such as PRD, PRI, PRY
The PRI is the signal that "tells" to the microprocessor that something is wrong with the power amplifier stage. so my recommendation is that look with the ohmeter a power transistor shorted usually if one if damaged, the next one or complimentary is too, there is a small transistor between the two big ones, usually is the number is D1915, if this is damaged, USE the SAME, also look for resistors damaged, specially the low value like the big white this resistor is 2 in 1 and some times just one resistor opens.
I hope this helps
