Question about Pioneer VSX-515 Receiver

5 Answers

Won't power on

My VSX-515 is less than one year old, and suddenly stopped turning on at all. The unit was always surge protected, and there are no blown fuses on the inside. I believe that the AC outlet might responsible, as it briefly had a device that drew more power than a normal CD-player, DVD, etc. It there any easy way to rectify the situation?

Our VSX-515-S quit suddenly while playing when it was turned up quite loud. The power would not come back on. I disconnected it, and opened it up. No fuses were blown, but there was no voltage in the power supply. When I pressed the on button, I could hear a very faint click, but no power. I even took some parts out and replaced them.

I went on line and bought a service manual download for $7.95.

Within 5 minutes, I found where the service manual said if there was a DC overload, the power would cut off. To reset, press the ENTER + ADVANCED SURROUND key simultaneously and hold for 3 seconds.

I did this and the power came back on. It even remembered the last FM station it was tuned to. Problem s.olved

Where these units appear to no power, the fluro display doesn't light up yet there is power : the VSX-515K suffer from dry soldered joints on the PCB in the power supply/relay circuits.

Getting Rapairs For This Unit may not be an option, I went to pioneer site for support and this particular model wasn't listed. There was a support box that allowed u to search for a service center but did not have the 515 model listed only newer updated models which means they may not be offering replacement parts or service for that unit.If u do get the unit repaired , u must look at the environment thatn,u have your receiver in, remember receivers generate lots of heat and need space to vent that heat otherwise the parts inside generating the heat will overheat and stop working.

If its less then a year old, take the unit with the bill of sale to an authorized repair depot. Most recivers like this have a 1 to 2 year warranty

Pioneer VSX-818V receiver. less than 3 years old. Getting no sound out of speakers all of a sudden. Signal to TV is ok just no sound. What component drives the sound out to the speakers? The sound stopped,...


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

My VSX 515 jumps from CD to AM unexpected and this happens at irregular intervals, is there anything I can do.


I'd suspect another infrared transmitter in the vicinity. Try blocking the 'eye' on the receiver and completely hide all the remotes you know about and see if it stops.

A bad relay won't pick and release itself. You need to find the cause.

Here's the Service manual.

All of a sudden none of the buttons work, we can't change any channels and it will only turn on. The TV is less than a year old, is plugged into a power strip (so there won't be a power surge), and was...


Not all power strips prevent power surge, only those that specify on their packaging or imprinted on them, that they are "surge protectors". Also, even these will have lost their surge protection once they have been hit either by lightning or a strong power surge. You would have to check with the manufacturer on how much of a hit they can withstand. Was there a thunderstorm in your area recently? Are you using a remote to try to change the channels? If so, try the buttons on the tv itself. Also try unplugging, waiting 15 or more seconds, plug it back in, directly to the wall socket. See if that resets it. If you still can't get it to change channels call the manufacturer of the tv, it may be a known problem and they may be able to help.

The unit wont power up it is stopped at the first power relay. iT SEEMS THE POWER RELAY IS BAD. cAN IT BE FIXED


If the power relay clicks, this means that the coil is good but the relay contacts may be dirty (contacts need to be cleaned or the relay replaced).

If the relay does not click, then it might be a bad fuse, a bad relay coil or a faulty relay drive circuitry, no power to the relay drive circuit, possibly an internal overload or a short somewhere in the unit which causes the unit to stay off to protect itself from further damage that might occur if it had turned on.

Speakers for pioneer vsx 1018


I think you're making this way more complex than it is.

This unit should have no trouble with any reputable speaker. Don't read too much into short term impedance readings as long as you run only one speaker per channel. Every speaker has a dip somewhere in its frequency range and the Pioneer will probably protect itself and the speaker should impedance or current get too out of whack. This is a high end unit and has plenty of clean power to feed any speakers out there.

I'd buy it if I didn't already have a 6-year old predecessor (VSX-T36TX) that I paid twice as much for and has only 5 amplified channels, less features and lower power output. ;-(

Good luck and happy listening!

If there is no power at all, then try bypassing surge protector, check power cable, and check if power cord is fused.

If unit has power but does not start, then it is on protection.

Protect mode will kicking whenever a fault is detected.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Pioneer VSX 915 powe off


Had a power surge last night and got the same problem. Unit wont power on and has a blinking blue light on standby button. I found the solution from the service manual for a similar model.

Hold down ENTER and ADVANCED SURROUND buttons.

This resets the DC overvoltage sensor and bingo the unit comes back to life again.

UPS issues with bad power


First, most of the UPS sensitivity can be adjusted. Setting a higher sensitivity will make the UPS compensable much faster if the current goes to high to too low thus always providing a good power quality to the equipments. For example, on a BackUPS RS the low level can be configured from 94V to 104V and the high level from 126V to 136V. An entry-level UPS such as the APC BackUPS ES will switch to battery mode as soon as the power goes out of the sensitivity range. On the other hand, a high-end UPS for workstation like the APC BackUPS RS has a feature called Automatic Voltage Regulation (AVR) that compensate at some extent without requiring the battery; this makes the battery last longer before needing to be replaced.

Second, most of the UPS have "Battery Protected" and "Surge only" outlets. Make sure that the computers are connected to the "Battery Protected". The "Surge only" outlets will only protect from parasites or surges like a thunder storm. They should be used for less important stuff like a desk lamp or devices with high demand peek such as a laser printer.

Third, the use of a power bar connected to the "Battery Protected" side should not have any impact as long as it is not overloading the UPS. Personnaly, I have a power bar connected to both my UPS.
