Yes turned on but amp error then shuts off

Pioneer... | Answered on Nov 29, 2020

The diagram that I looked at real fast did not have a lot of detail. There are filter circuits in that unit to keep the sub woofer channel in a specific range and there are circuits called op amps that drive those filters. You could have a bad filter component or a failed OP amp. IT will take special equipment to find and replace the bad part. IT could be a weak soldering connection also.

A lot of audio and studio equipment is SMT now and is not easy to work on. It could be a CPU or any of a number of issues with finals, capacitors etc.

It will probably be easier to wire the sound bar to the "Audio Out"" on the TV, the DVD player to the HDMI on the TV then change the settings in the TV.
On the back of most TV's there are 'Phono Jack' connectors and newer TV's have a 'Digital Out' that uses an Optical cable to transfer the sound. Use one of these to connect the sound bar and usually anything you play through the TV will play through the sound bar.
Depending on your TV, the settings to switch to the sound bar will be in the Sound or Audio section.

Hi, Try pushing the "Advanced Surround" and "Enter" buttons together for about 3 seconds.

For me on vsx 1016 txv it was ENTER and DVR/VCR2 for 2 seconds. Blue power power button lit up. Then it went back to MCACC flashing amber. So probably blown amp.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. /

Is it hot? You can't reset reality with a switch.

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.

Just guessing - for a considerable time amplifier output stages have often used encapsulated modules rather than discrete components. Like everything else these arrive in different qualities.

High quality amplifiers tend to use higher quality output modules - the best have built in overload protection and thermal shutdown and I expect that could be what is happening, something inside the amp is cooking and when it becomes too warm it shuts down.

I suggest you take it to the repair shop before the problem becomes really expensive.

Did you fix it? I have the exact same problem

Pioneer Audio... | Answered on Aug 13, 2020

It's in the manual. Page 12.

Resetting the Main Unit
Use this procedure to reset all the receiver's settings to the factory default. Use the front panel controls to do this.
1 Switch the receiver into standby.
2 While holding down the BAND button, press and hold the STANDBY/ON button for about two seconds.
3 When you see RESET? appear in the display, press AUTO SURROUND/STREAM DIRECT.
OK? shows in the display.
4 Press STEREO/A.L.C to confirm.
OK appears in the display to indicate that the receiver has been reset to the factory settings.

There might be a fuse either in the rear panel or inside the case that might be worth checking. Manuals can be downloaded from the link below, though the best advice I can offer is entrust the diagnosis and fault to a professional.

Pioneer Audio... | Answered on Jun 19, 2020

I sounds like you may have a problem in either one of the Regulator circuits, or, one of the Power Amplifier outputs. If the protect circuit detects DC or Low Impedance on one or more of the speaker lines, it will not fire up the high power section of the power supply. Further troubleshooting will require some working knowledge of power amp and power supply circuits. I've got a .pdf copy of the Service Manual if that will help you.
Please let me know what your level of troubleshooting ability is, and whether the manual will help you.

It would go into protection mode to stop damaging other components...... until the fault is rectified it will not stop going into protection mode!

Usually this is caused by a short in the wiring, get this tested!

Power supply issue

The shaft on the motor is not lined up with the turntable or gear. Adjust the motor (if possible) so it’s properly aligned. Also, clean motor shaft with rubbing alcohol.

That all depends what is wrong with it, which you never share.
