"I accidentally touched a speaker wire to the metal spikes on the bottom of my speaker. " This action makes +B voltage (positive voltage) short to ground. You may assume 2 power transistors mounted on a large heat sink are defective. Now try to remenber which speaker terminals was accidentially shorted. Then check this terminal or you should check all power transistors mounted on the heat sink, by measuring the collector and emitter resistance. Normal value is Mega ohms and all white 3 pins resistor with 0.22ohm should also be checked if they are open( infinity resistance).I have tried to reset it several times to no avail. Of course, due to defective power transistors. Is my receiver done? Yes. I wrote detailed troubleshooting steps used in onkyo service dept. a year ago, just find it out in my answers.210cda21-872d-438d-949c-2196ccf76712.jpg

“Hi, Onkyo TX SR 705 have a super cap for memory presets ou eeprom?? ”
Yes, it may have a 5.5V cap with 0.1F for memory to use .When the power is down and it loose the presets, whats the problem?? Tks
Don't worry, it will be charged up when the amp is On. The longer the time it is on, the longer the time it charged.For your case, replace the cap mentioned above can fix the problem. I will post the photo later.

After checking the onkyo TX-SR705 service manual, however, I did not find any capacitor of 5.5V 0.1F on the schematics. The EEPROM is powered by a polar capacitor. See photo.

Step of repairing
(1)Download the onkyo TX-SR 705 service manual.
(2)Find out the EEPROM located at Main Microprocessor Unit.
(3)Replace the capacitors of epprom
(4)If the problem doesn't solve, copy
all data form the old EEPROM by a SPI EPPOM reader.
(5)Buy a new SAME MODEL EEPROM and copy the old data to
the new one.
(6)remove the old defective one from the circuit board
(7)put the new one with data copied to the circuit board.7abf1fe5-29df-4e3d-98b4-8e2ba153ec59.jpg

Hello Hasnul, for what you comment, it is very possible that the integrated circuit has been burned, that works with the Front System A output and you have to replace it, the Front System B output, works with another integrated amplifier circuit, which is working well
If you have technical knowledge, I send you the link to download the Service Manual of your Onkio and know which integrated circuit to replace
But, I suggest you look for a specialized technical service
I hope you can solve the problem, comment the results
Greetings Franco Dosil

Hola Hasnul, por lo que comentas, es muy posible que se haya quemado el circuito integrado, que trabaja con la salida Front Sistema A y tengas que reemplazarlo, la salida Front Sistema B, trabaja con otro Circuito integrado amplificador, que esta trabajando bien
Si tienes conocimientos tecnicos, te envio el link para que descargues el Manual de Servicio de tu Onkio y sepas que circuito integrado reemplazar
Sino, te sugiero busques un servicio tecnico especializado
Espero que puedas resolver el problema, comenta los resultados
Saludos Franco Dosil

Hello Scott, to be able to guide you, in wiring so that you can have everything in your home theater system, you should comment that equpos you have
I can suggest a generic connection to have the sound of each source in Tu Onkyo
You have to connect the equipment that has HDMI output, in the corresponding entries in your Onkyo, accounts with only three inputs, if you have more than three equipment with HDMI, you can connect it to an HDMI input on the TV
If you have other equipment that does not have an HDMI output, you should connect it to the remaining inputs of the Onkyo, according to its type
Then, you connect an HDMI-HDMI cable from the HDMI output of the Onkyo, to the HDMI 1 input, of the TuTV Insignia
And you also have to have a Fiber Optic cable, connected from the digital audio output of the TV (it is located on the side panel of connections) to the Fiber Optic input (Digital In) n ° 1 of the Onkyo, this connection allows you to listen to the sound on the Onkyo of everything you are looking for on the Internet, eg Netflix, YouTube, etc.
In this way you would already have everything connected in the Onkio and you could enjoy the sound of the Home Cinema System
I hope you manage to interconnect everything and you can enjoy a good sound and an excellent image
I send you the links of the user manuals of TV Insignia and Onkyo, in case you need more information
Greetings Franco Dosil

Hola Scott, para poder guiarte, en cableado para que puedas tener todo en tu sistema de cine en casa, deberias comentar que equipos tienes
te puedo sugerir una conexi?n gen?rica para tener el sonido de cada fuente en Tu Onkyo
Tienes que conectar los equipos que tengan salida HDMI, en las entradas correspondientes en tu Onkyo, cuentas solamente con tres entradas, si tienes mas de tres equipos con HDMI, puedes conectarlo a una entrada de HDMI en el televisor
Si tienes otros equipos que no tengan salida HDMI, los deber?s conectar en las entradas restantes del Onkyo, de a cuerdo a su tipo
Luego, conectas un cable HDMI-HDMI desde la salida HDMI del Onkyo, hasta la entrada HDMI 1, del tu TV Insignia
Y tambi?n tienes que tener un cable de Fibra ?ptica, conectado desde la salida de audio digital del televisor (se encuentra en el panel lateral de conexiones) hasta la entrada de Fibra ?ptica (Digital In) n°1 del Onkyo, esta conexi?n te permite escuchar el sonido en el Onkyo de todo lo que buscas en Internet, ejemplo Netflix, YouTube, etc
De esta manera ya tendr?as conectado todo en el Onkyo y podr?s disfrutar del sonido del Sistema de Cine en Casa
espero que logres interconectar todo y puedas disfrutar de un buen sonido y una excelente imagen
Te env?o los link de los manuales de usuario del TV Insignia y del Onkyo, por si necesitas mas informacion
