The problem is the Ic or transistor use a tester

OK, it looks from what I can tell you need a 1/4" stereo plug for the input to your speaker system. The output from the TV is either RCA jacks or maybe a 1/8" sub mini stereo jack. You can likely go to Radio Shack or an audio store and purchase a cable that has the 1/4" stereo plug on one end and a 1/8" sub mini stereo plug on the other. That cable would mute the TV internal speaker or if you do not want to mute the TV speakers you can get a cable with the 1/4" stereo plug on one end and the L and R audio, RCA (phono) plugs on the other. That would give you both. RCA plug and 1/4" plugs are pretty easy to install if can not find the correct cables. Good Luck. The Yamaha unit looks to be self powered so impedance matching or load on the TV audio amps should not be a problem.

It takes two to tango.

See the manuals for both the sub ...

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 ..
