Unplug all your speakers and components. Then turn on, if it still locks up you have one of maybe 5 safety features hooked up that are built in to stop your amp from blowing. You will need to replace board or have some cool tech dude desolder and isolate . Look for wiring diagram for safety shut down system. Sorry but if it doesn't do it after you disconnect every thing then check each speaker with ohm meter to read factory specs.
Hi Andrew Smith, as you comment, the problem would be in the remote control
You can do a test to see if the remote control is broadcasting
You put the camera of your cell phone focusing on the emitter of the remote control, press any key on the remote and through the camera you will see that the emitting LED turns on (this happens through the cameras of the cell phones detect infrared rays, our view can not do it directly)
With this method you can check if they are emitting each key of the remote control
If you don't emit, you can try cleaning the internal contacts
Try to carefully disassemble the remote control
Separate the plate and the rubber template from the keys, clean the latter with some neutral soap, removing the grease that forms in the contact area, on the other hand, clean the plate with a cloth dampened with a glass cleaner, NO USE ALCOHOL in any case, let all parts dry and reassemble
Take the test and comment

Hola Andrew Smith, por lo que comentas, el problema estaria en el control remoto
Puedes hacer una prueba para ver si el control remoto esta emitiendo
Colocas la camara de tu celular enfocando al emisor del control remoto, presionas cualquier tecla del remoto y a traves de la camara veras que el LED emisor se enciende (esto sucedepor las camaras de los celulares detectan los rayos infrarojos, nuestra vista directamente no puede hacerlo)
Con este metodo podras comprobar si estan emitiendo cada tecla del control remoto
Siencuentras que no emiten, puedes probar limpiar los contactos internos
Trata de desarmar con mucho cuidado el control remoto
Separa la placa y la plantilla de goma de las teclas, limpia esta ultima con algun jabon neutro, sacandole la grasitud que se forma en la zona de contactos, por otro lado, limpia la placa con un pa?o humedecido con algun limpiador para vidrios, NO USES ALCOHOL en ningun caso, deja secar bien todas las partes y vuelve a armarlo
Haz la prueba y comenta

Hi Tony mucci, to connect your Yamaha EQ-70 equalizer to the RX-661, you must use two double RCA RCA cables and the Line IN connection of the EQ-70, you go to the RX-661 MD / CD-R Rec connection and the Line Out connection of the EQ-70 you go to the MD / CD-R Play of the RX-661
This equalizer will work with the analog audio signals, but not with the digital ones
I hope you can connect it
Greetings Franco Dosil
Hola Tony mucci, para conectar tu ecualizador Yamaha EQ-70 al RX-661, debes utilizar dos cables RCA RCA dobles y la conexion Line IN del EQ-70, vas a la conexion Rec de MD/CD-R del RX-661 y la conexion Line Out del EQ-70 vas a Play de MD/CD-R del RX-661
Este ecualizador va a trabajar con las se?ales de audio Analogicas, no asi con las digitales
Espero lo puedas conectar

(1)download yamaha rxv663 service manual.
(2)read p.152-154
(3)make sure your remote matches with remote ID.
how to check remote IR diode
(1)switch on mobile phone camera
(2)point it to remote IR diode.
(3)Do not take any photo & press any remote buttons.
(4)White light flash.
how to check IR receiver
(1)locate the front panel.
(2)find out IR receiver.
(3)find an analog multimeter with 0.5V selected.
(4)black probe to ground, while red one to IR pin.
(5)press any remote button.
(7)deflection occurs
"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,two0.22Ohm resistors and biasing circuit such asall 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 allpower supply circuits, including regulators andcaps.
Hi Bryan Fenwick, if your Sky + HD Box-Wifi-2TB, has a unique audio output and is an optical type (Fiber Optic), you will not be able to connect it to your Yamaha CRX-D430, because it does not have such inputs , the fiber optic connection you have, is an output of the compactera
You should buy an audio signal converter by fiber optic to audio signal, L R, with RCA
Hola Bryan Fenwick, si tu Sky+HD Box-Wifi-2TB, tiene una unica salida de audio y es tipo optica(Fibra Optica), no vas a poder conectarlo a tu Yamaha CRX-D430, por que no tiene entradas de este tipo, la conexion de fibra ptica que tiene, es una salida de la compactera
Deberas comprarte un conversor de se?al de audio por fibra optica a se?al de audio, L R, con RCA

In some old model av-amp, if the sampling freq. is 96KHz or
above, av-amp confines its playback in 2 channels only.
Check the sampling input source is 96KHz or not.
Or perform this test
(1)Download htr6130 service.
(2)Start the self-diag test
(3)follow the instructions written on p.25 to 33 to do the tests.
