"My Yamaha receiver RX v575 will not power up it has a blinking red light when trying to power up "
Never press power button more than 3 times. Your amp will be locked, otherwise.
(1)Download RXV575 service manual.
(2)Read P.25 to 29 to see if protection occurs.
(3)Read P.31 and follow the diag steps.
(4)If I protect, check all power transistors,two
0.22Ohm resistors and biasing circuit such as
all components connected to Q2022 of front L channel, on P.108.
(5)If dc protect, check if DC comes out from speaker terminal, opening metal cover required.
(6)If thermal protect, replace a thermal sensor.
(7)If power supply problem, ps prt, check all
power supply circuits, including regulators and
caps.

SOURCE: Yamaha Receiver RX-V630 not working (resets itself immediately)

This maybe an easy one. Have you unhooked all the wires going in to the stereo. "SP wires" means you have wires to the speakers are touching and the stereo is shutting down to avoid overloading. Hope this helps...

SOURCE: Yamaha RX-V596 Receive turns off after pressing Power

Sometimes the receivers turn off if the speakers are shorted in order to protect the AMP circuit. So try this - 1. Disconnect all cables (speakers), inputs from Tape Deck, VCR and other input devices), sub-woofers, rear speakers all. Except the AC power cord. Then turn it ON and see if it stays on. If it still has the same problem, then most probably your power circuit inside the receiver has a problem - like a shorted Capacitor or diode etc. Based on how technical you can be and what resources and time you want to spend, this is repairable. But based on the price of a receivers these days, it is not worth. Good Luck!

SOURCE: Yamaha RX-V995 receiver turns on & then powers off 2 seconds late

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,

No HDMI video using RX-V575 Yamaha Receiver with Panasonic TV C-P60ST30


Michael, I still think it is a connection problem. Try disconnecting the HDMI and see if you get the video. If no, it is a connection problem. Check the connections carefully.

No on-screen display of the unit even if the proper source is selected on the tv. It worked the first days and then it disappeared.


thats needs a technician to follow the voltages and maybe find out if there are damaged components.
