20 Most Recent Yamaha DSP-AX1 10-Channel Amplifier - Page 2 Questions & Answers

Hello amos78

First, perform a visual inspection at the back of the unit and verify that speaker wires are not loose or shorting out with another connection. Find the impedance selector switch and verify that it is set to the proper position according to your speakers' impedance. It has to be all the way up or down, never in the middle. (Warning: Do not move the impedance selector while the receiver is powered. Make sure power is OFF on in standby, otherwise receiver will be damaged). Try power ON.

If these actions do not cure the problem, disconnect all speakers and try power ON again.
If the unit powers on, it is possible that one or more of your speakers or wires are damaged.
If none of the above actions fixes the problem, it is very possible that the receiver's internal circuitry is damaged.

Hope this helps you. Let me know.

apply a good contact cleaner in this button and press it many times.confirm good connection between amplifier output and speaker b.connect speaker A insted of speaker B if it is working the problem will be in cabel and speaker B if not the problem in your amp output stage.

disconnect the cabel of left channel from your amp disconnect the cabel of right channel and put it in place of left channel if the problem goen your problem is in left speaker itself (cabel or speaker).if the problem excit the problem will be in amplifier output stage

Just throw it away and buy a new one.

If your amp is less than 5 years old you maybe able to get it fixed for free at http://www.domgen.com check it out we have all our contents covered. This is better than your normal home insurance. Don't matter you could claim 100 times and never loose out. check it out! Also don't 4get to leave me feedback cheers raverbaby01

does the speaker relays work?

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 ..
