Why my Receiver shut down? Need help!

[titogap]

Hi, I have an Onkyo TX-SR705 from about six months and working perfect, until begin to shut down(protect mode). This action is at random, sometimes work perfect and sometimes I can't see my movies or play with my ps3. I have connected the PS3 through hdmi, a cd player through digital. All my equipment connected to a battery surge protector. It's the receiver or some source of my equipment? Can somebody help me? I begin to pulling my hair and to beating my head against the wall.

I appreciate your comments and help that you can bring to me.

9 times out of 10 the problem is a short in the speaker wiring.
Check your connections for a stray strand of wire.
If you don't find anything; disconnect all the speaker connection at the receiver end and check to see if the problem still persists. If it does, then it's most likely a problem with the receiver.

I had the same thing happen to me two months ago on my Onkyo 805. I checked all the speaker wire (which is always a good suggestion, because it is 90% the cause of why a reciever will go into protect mode.) But if your speaker wires are all fine (which mine were). I found after I sent my Onkyo to the Regional Service center (at my expense of 80.00) that the *05 series are suffereing alot of broken recievers because of bad solder joints. In fact this is the main cause of the recievers going into protect mode according to the lead tech at Onkyo whom I talked to. So if you are using banana plugs or don't have any stray wires, the bad news is that you'll have to ship the reciever to Onkyo to get it fixed. But they fixed mine pretty quick (five weeks) and they also repaired other issues that I read online that I brought up to the lead tech. (i.e. upgrading capicitor from 1/4 watt to 1 watt on display that many have reported shorting out). Sorry to hear of your problem it is a pain in the butt.

I knew these problems would start showing up. The EEC banned lead in solder. Now no solder with lead is used. About two years after manufacture, and sometimes before, lead free solder sprouts whiskers and causes shorts on circuit boards. This is going to become an epidemic now with all gear manufactured in the last two years. It is now just over two years since lead free solder started being used exclusively. Expect an epidemic of this.

Any real solutions to this whisker issue with reformulated solder?

No there are not. This issue goes back to the early days of radio. In the first world war there was severe problems with the communications equipment because of this issue. The British MOD commissioned a study of the problem. The solution was to add a little lead to the solder.

This has served the world just fine, until an EEC commission poked its nose in and banned lead as part of their ridiculous RoHS regulations.

I should qualify the remark slightly. There is the solution if using pure silver solder. However that puts electronic gear out of the reach of the average consumer, and certainly precludes budget receivers. Most high end gear now uses pure silver solder, and that is just one of the reasons for their high cost.

Silver lining - it provides a valid reason to give to your significant other when you want to upgrade. After all, what true AH keeps gear for longer than two years?

Just for the record, it is a resistor. For Onkyo owners who read this thread and might be worried, just put your display setting at low. High setting is extremely bright, due to choice of resistor. There are detailed, step by step, photographed instructions at the 805 thread at AVS if you want to replace them yourself.

Sorry, Matthew, but I'm glad you got squared away. If at least for now.

Hey guys you are a great team. I checked all connections and are perfectly. All the speakers are connected with new banana plugs and spade connectors. I appreciate your comments.

I will send my receiver to the service. I have a service station near in my city.

Are we certain this is the result of new solder? I have found many electronics pre-EEC banned with poor soldering. Engineers can find way to use any kind of solder as long as they know what the requirements are. Plus many electronic devices don't need as long of a life anymore.

If there are soldering issues it is likely a product of bad engineering or manufacturing not simply the type of solder used.

I have yet to see statistics that prove products have a higher failure rate than before. But if you have some please link them.

Frankly I think this is probably not always the case in most of the 05s. Some of them probably suffered from this defect, but I doubt it's as widespread as it seems.

Have you ever tried using lead free solder? I have, and its terrible stuff. I would never use it on anything I would want to last. I have a lot of gear that is very old and still working. That is the way it should be. I buy gear for the long haul.

Oops yoru right Jostenmeat, it is resistor, for some reason I always say capicitor, but you are correct. Sorry for any confusion. I will try and edit my original post.

Dang can't edit it, sorry to anyone who was confused.

Isiberian, I was just converying what the lead tech at the Colorodo Regional service center told me. He said they were hugely backlogged with 05's because of bad solder jobs and resistors that need to be upgraded from 1/4watt to 1 watt to solve the display failure that was happening also.
