My Yamaha RX-V995 receiver turns on & then powers off 2 seconds later. Do you have any suggestions for fixing this? The receiver is in perfect condition otherwise.
I suggest you run self diag. press [FM/AM] key + [Input mode] key and press the [power/standby] switch.
ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink
you'll likely have to measure the resistances of the output FETs to find a short,
Also the unit has a output from the DIAG mode. Â Connect a TV or monitor to the [monitor out] video plug on back of unit. Â for more options. Â Â
Correction: Outputs are NPN and PNP transistors not FETs.
Another thing is that the input selection board can prevent the unit from starting. Â Â
The white ribbon closest to the rear on the DVD/TV/VCR1/VCR1 Â input board to the neighbor board [input selection board, Phone,CD Tape inputs] Â
Remove one end of the ribbon Â
Overloading inputs might of blown the switchs
The unit might stay on then
If your a tech check the voltages of the PRD and PRV lines both need to be near zero. the PRD is DC voltage present on outputs (possible shorted output) Â PRV is bad voltage from supply. Â if both are near zero try the inut disconnect trick above
we did the above pressing all 2 buttons and our unit turned on but pcm appeared on the screen?????

I have the same issue with my RX-V992. I wonder if the new year causes a system problem for these Yamaha receivers? ;-)
I have the same issue. I noticed one speaker was not working so I pulled everything out and after doing that, the receiver goes on for a couple seconds and then turns off. It is working again now but there has to be a short or something some place. I now have the right speaker on the B speakers and the left speaker on the A's and everything is OK as the receiver is staying on, but something is not right. We have a large party coming over to watch the NFL Sunday and could not imagine that the stereo(we run everything through this to get the 5.1 sound) would not work!
i have the same problem hit power button clicks on and off when everything is unplugged as well what can be done ?
i have same exact problem
self diag shows dc prt = 0%. What does this mean?
My Yamaha RX-V995 was working for several years.
But now, it has this problem:
1. When I turn on the STANDBY/ON Switch, I can see the
FM stations number displayed.(Because the Input Selection
is selected as FM. )
2. After about 2 seconds, I hear a "click" noise, then the
power is turned off automatically.
During this 2 seconds, I can even change the "Input Selection" from FM to DVD.
But after 2 seconds, it turned off.
I tried many times and same problem.
Can you help me to find out what is wrong and how to fix it?
Thanks!
