Pioneer Audio Players & Recorders - Page 7 - Answered Questions & Fixed Issues

Check to see that the A/C power cord is plugged into the electrical outlet and the power on the unit is turned "On" if the receiver will not power up. Test another appliance in the same outlet to check that it is "hot." Check the household fuse box for blown fuses and tripped breakers. Reset breakers and replace blown fuses with others of the exact same rating. If you are using the remote control, check the batteries and replace them, if necessary. As a last measure, remove the power cord from the electrical outlet and then reconnect it to try and reset the system.

Yes turned on but amp error then shuts off

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.

Your Pioneer unit has gone into protect mode because of component failure. Use your multimeter to check continuity and voltages at the component level. Also check for cold solder joints.

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.

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.

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

http://audio.manualsonline.com/manuals/mfg/pioneer/vsx819hk.html 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. https://www.hifiengine.com/manual_library/pioneer/sx-251r.shtml

The connection to the receiver from the TV is faulty!

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!

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.
