Get a better translator. Sounds life bad solder job on board. Check buttons wire connections and where they hook up. If it'd the display which I Dont think it is try checking those wires. Good luck.

Power on problem

Sounds like a defective switch.
To check it, with the power cord unplugged from the wall outlet or power strip, use an ohm meter to take a resistance reading across the switch when you press it to the "on" position. If the reading drops to zero, its a good swithch; if you get a high reading- the switch is bad. You may want to press the switch on and off several times while taking the reading to see if you can reproduce the fault. It may even be a loose solder connection to the switch.
Please make sure you run this test while there is no voltage power going into the stereo because serious electrocution and death can occur.

Power won't stay on, keeps turning itself off after only 2-3 seconds

it is either a short on one of your speaker lines or it could also be that one of your PCI's have blown.

My AV receiver turns off a couple of seconds after I turn it on. I did what the manual said, unplugged the power source and removed all of the speakers but it continues to do the same thing. Anything else...

you may have a bad Earth power 110 V AC cable connection which makes such hum / buzz even nothing connected..
Check the connections between components and make sure they are secure before proceeding to the next Step. Sometimes, loose connections can cause a hum.
  • Separate the audio cables from the power cables; electromagnetic interference from the power cables can cause stereo hum. Use cable ties to secure the audio cables away from the power cables.
  • Plug in a surge protector to the outlet, and then plug all the components into that surge protector
  • Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
  • 5 Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

    Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
    connect the ground wire to a screw on the electrical outlet.

    Avr-5700 One of my channels is crackling. I was told some kind of reset would help.

    You can reset your reciever by completing three simple steps

    1.Switch off the unit using the main unit's power switch

    2.Hold the following DIRECT button and STEREO button, and
    turn the main unit's power switch on.

    3.Check that the entire display is flashing with an interval of

    about 1 second, and release your fingers from the 2 buttons
    and the microprocessor will be initialized.
    If step 3 does not work start over and attempt again. Be aware this will reset all setting to factory defaults. Hopefully this helps.

    well, if it powers up, youve still have hope// check and see if you can see a fuse holder at back of stereo... or go to a radio shack or electronis place and get whats called 'contact cleaner' ( may go by a different name, make SURE you know that the salesperson knows what your talking dont have to buy the pricey stuff, but dont get the cheapest either.) then UNPLUG stereo, make sure its not hot ( dont have it on for a long time before working on it) then pull out the knobs on the front ( the volume,left/right,etc) spray a LITTLE bit into the stereo where the plugs go.dont drench it, a little goes a long way) after spreying it in, turn the knob back and forth so it gets to all the points.... make SURE its dry before plugging it back in, you can tell if you see any moisture where you sprayed.( another reason, not to spray much) i usually let my stereo and tvs dry over night before trying them.while your waiting, may as well take a cloth and clean the face, get any cruddies off... good luck
