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.

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.

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.

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.

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

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. -Petra

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.

Could be a dry soldered joint - not unusual in complex electronics but randomly heating lots of joints can cause trouble so it is best to discover the fault first, if possible. Obtain a service manual and trace the power path with a suitable multimeter.
