do it!

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

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.

hi, i had a problem with my sony unit that might be similar to yours (worth checking anyway). If the input is good and the output is missing or not there, If you can disconnect the output from the unit then check for an output from the unit . Sometime you have to remove a unit from the circuit and then check it out. If this is O.K., you have something in the rest of the circuit loading it down. But at this point you know this part is working O.K. You might find your answer somewhere down the rest of the circuit. hope this will help.

1. The power cord is not completely insered. 2. the impedance selector switch on the rear panel is not fully set to the upper or lower end - (set it when the unit is in the standby mode) other then that, you will have to call for a service.

I expect there is either a power supply issue or one of the amplifiers has failed causing over current to turn it off as a protection to the power supply.

"Opening" ... Please explain what you mean.

Yes if it has a suitable speaker connection available and is nominally 8 ohms impedance Speaker and AV.

Being from 1985 or there abouts, it probably needs some TLC at a Yamaha service centre. May need new capacitors and resolder dry joints for age related issues.

WD-40 ... Very dangerous as it not only flammable when wet but is bad for electrical contacts as it leaves a residue behind that does not conduct electricity very well. Check speaker connections first.

(francais) hello in my issue the probleme was a little resistor r027 it's in this red zone and very ugly. easy to find. a friend was unsolded the resistor and weld a little wire after wash with isopropanole alcool. the resistor test the tension when we plug usb thing. less the resistor the usb ports don't work. you can buy r027 for 2 euros for 100 pieces.... or 2 euros for 5 10 pieces (funny).

Follow the procedure as given in following link. RX-V6A ' ENJOYING IN MULTIPLE ROOMS (ZONES) (yamaha.com)

Question edited for clarity, full make model (what it is)'. Question moved to Yamaha Audio. It may be sympathetic vibration and is coming from something nearby. Put it on a folded towel or sit in the floor to test it. https://www.google.com/search?q=YST-FSW050+bad+vibration ..

You must repair the amplifier first. Take it to an authorised Yamaha service centre.

Visit 00_HTR-5750_U_EN.book (yamaha.com) and see page 59 (Troubleshooting).

Visit YAMAHA P-155 P-155S P-155B SM Service Manual download, schematics, eeprom, repair info for electronics experts (elektrotanya.com) for service manual. Check the pre-amplifier and power amplifier section.

You can't do this. The SpeakerCraft is a standalone amplifier. The Yamaha is a Receiver and has its own amplifier. Putting amplified sound into a data input is not recommended and will cause component damage and overload 'clipping'. https://www.google.com/search?q=SpeakerCraft+BB275 https://www.google.com/search?q=Yamaha+5.1+receiver I deleted the two answers from AI Answer Bots as they are not doing you any favours suggesting it can be done in their waffling answers! ..

Thanks for the compliments Gilbert. You have tried the reset so a Yamaha audio tech is the answer. This link will find you one close to where you live. There is probably a glass fuse on the power board, but you have to find out WHY the fuse blew? It is worth fixing in my opinion. https://www.google.com/search?q=yamaha+audio+repairs+near+me It does have a thermal fuse https://www.google.com/search?q=yamaha+rx-v663bl+no+power+on ..

Question edited for clarity and all the typos. The Yamaha receiver has to have a sound source and the speaker wires connect the two together. Receivers often have a a switch for Speaker set 1 and Speaker set 2, so you can send the music to two different rooms. Make sure you are on the correct set. These are supposed to be standalone television speakers by the looks of it connected to what they call an 'AV Processing Unit', I would guess more commonly called a Surround Sound Theatre System. Expensive speakers at $900. https://assets.kef.com/uploads/files/en/series_pdf/T301_T301c.pdf https://www.google.com/search?q=kef+t301+no+sound+from+speakers https://www.google.com/search?q=kef+t301 ..
