I have a mitsubishi m vr-700 receiver and I had someone hook up the five speakers up to it last night. It was working fine. This morning I turned it on and no sound. how do I fix this?

I bought a Mitsubishi M-VR700, which produced no audio from the speakers, but with headphones, a tiny bit of audio was detectable with the volume control on max. This solution was posted on FixYa by Mojorisin65 some time ago: Facing the receiver directly behind the MITS logo & power button is a vertical board with a large IC on it, try flexing the board near the IC while turning the reciever on & off or changing input modes, there is a cold solder joint on this board which I haven't found yet. I understand this is a common problem with the MITS M-VR700-900, Onkyo TXDS-575, & Integra DTR5 or DTR5.1 ( all made by Onkyo).
I gently flexed the board as described, and Boom, all the audio was back as it should be. I suspect Mojorisin65 is correct about the cold solder joints, but with SMT components, it could be very difficult to find. I may very well be on one or more of the 48 pins on the large IC. This IC gets rather warm during operation, which may explain why some units may work until it heats up. The chip gets warm and 'twists' enough to lift the bad pin(s) from the circuit board. In an attempt to deal with this symptom, I superglued a TO-220 heat sink to the top of the IC (don't let it touch the case of C-716). The heat sink is dissipating a fair bit of heat, and so far, this 'fix' seems to be doing the trick. RJD 10.18.11

I have an Onkyo TX-SR701 that won't turn on

The fuses are the first look, Then make sure that the speakers are connected properly and the wires are not shorting together. It sounds more like a power supply problem or logic controller problem if the unit will not fire up and as such unless you are into electronics then a repair center is the next option and most likely the quickest.

Let me be more specific on our problem. We installed the reciever according to directions. The 2 questions are: first, we have Dish Network. Isn't it possible to watch tv with the Yamaha reciever off with...

Look towards the back of the manual. You go into setup. Choose HDMI. Then there is another setting that you have to activate. The receiver must be set to the HDMI input that you want, before the receiver is turned off. I just installed my receiver last night and followed that procedure. Works great.

No sound from any source from speakers

check your connections again and ensure you have the audio going out. With many tv's you need to change a setting in the menu, double check that as well.

Yamaha HTR-130 5.1 reciever Not Turning On

If you are not into repairing electronics then the best bet is to
replace the unit.

What is happening is there are capacitors that have swelled

and need replacing .

I had a similar problem with the same brand and it can be fixed

but the cost would be greater than just replacing the unit .

Rx-dp15b reciever turns on, then immediately goes into standby

Just worked on a Sony with a similiar problem. I replaced the Power Amp Drivers. They were labeled as IC's on the circuit board. They were relatively inexprensive, around $33 total. This fixed required knowledge in using a Soldering Iron and Desoldering Wick. Also I had a schematic of the circuit board which can be purchased on the internet. Hope this works for you. It might be best to just have a tech look at it, if you have no electronics knowledge.

Usb sound card (m -audio)

All usb devices require power, by pulling it out first, sounds to me you've short-circuited it. Buy another.
