My RX V640 is 5 years old..no problems...no

theb best way to do this is to connect the DVR to the vhs unit and the vhs unit to the tv using red white and yellow for both connections. usually composite video 1,2,3 or 4. DO NOT involve the AVR at all, as it will cause your video and audio to be out of sync.The video will not be as sharp, until you play it threw an up-converting dvd or AVR.

When I turn on my Yamaha RX-V657 without the speaker wire connected, it only stays on for one second and then turns off. No error is displayed on the screen. Is this normal?

you forgot to see the AVR works prefectly using speakers 8,6 or 4 Ohms Z, selected to right ohms the switch. does it? if yes he below is moot, why do that. it there is sound source running, and loud and you have no speakers there, that can damage some amps. so don't do that, some AVR have no error code, protection lamp just relay clicks your AVR is really old a sea of RCA jacks on the rear. there is no need to run any amp ever, lacking a set of speakers. 7.1, does have rules here, no sure me miniumum rules. may be 2 are required min. (the selected set A or B) what I do is read the manual first . found it googled in 1second flat. page 88 The protection circuitry has been activated. Make sure all speaker wire connections on this unit and on all speakers are secure and that the wire for each connection does not touch anything other than its respective connection Check that the impedance selector setting is correct ok I have repaired amps (AVR and others back to 1960s) the protects circuits trip 1 or 3 ways or both (tech facts)
  1. over currant the PA (power amps at speaker jacks)
  2. or imbalanced driver transistor pair (push pull or class A)
  3. or overvoltages there. now.
so if it has way 3, and he source is full volume and heavy metal band then it trips. no speakers due to output is way too high. an amp that can do 1000w peak can do 90v peak to a speaker. yours is 95watts RMS each , peak is not stated. nor is protects stated in absolute terms. free https://www.manualslib.com/manual/340487/Yamaha-Rx-V657.html?page=18#manual answer 1,. turn off all sources and volume down to run no speakers. also it told you power off to connect. speakers. when you do not power on the surge in the PC can be huge so it tells not to do that.

How do I reset the protection circuitry on Yamaha RX-A820?

press and hold the 'tone control' and 'info' buttons and press power. This will release the protect. The first thing that show on the display will be the protect code to tell you why it shut down. If it turns right back off, then you most likely have a short in the amp that will need to be repaired.
