The User Manual says this is a result of the power being removed while the unit is still on. In order to reset this you need to:
1. Unplug the unit
2. Press and hold the the power key
3 While holding the power key, plug the unit back in.

This clears the units memory so you loose and settings you have set but the unit works again.

Hope this helps.

Hi, I have a Harmon Kardon Model No. AVR 325 that keeps clipping. When I push the power button the display turns off like a second after I push power. Seems like its a easy fix. Nothing if fried visually...


it sounds like Amp burned, but not all burn parts you can see, you have to measure them by DMM. I guess at least one AMP transistor shorted. you can check SPK terminals by DMM DC, it can be easy to find different with other one

Just bought yamaha rx-v467 reciever, it worked for 2 mins then it trips out, wired all surround sound correctly. now unit only turns on for 2 secs then turns off. it does it 3 times and then you have to...


This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic. 1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

I have an Onkyo TX-DS747 & everytime I turn the receiver on the speaker outputs a switch keeps turning on & off for about an hr before it rectify it's self. Is there a way to correct this issue??...


What it sounds like you are describing is the protection relay turning on then imediately turning off for the time period mentioned. That would indicate a possible short in the circuitry. Probably a capacitor that is intermittant or even a transistor about ready to fail. This is probably not something you can look for if you are not an electronic tech. Find a reputable shop and get it fixed before it quits and does more damage. Let me know how you make out.

My Denon AVR-1507 keeps automatically turning off every time I turn it on. Then the standby button blinks red. Is there a quick fix to reset the microprocessor?


Hi


Thanks for using FixYa. Store these instructions in a safe place. After reading, store these instructions along with the warranty card in a safe place. Whenever the power operation button is in the STANDBY state, the unit is still connected to AC line voltage. Please be sure to turn off the power operation button or unplug the cord when you leave home for, say, a vacation. Note that the illustrations in these instructions may differ from the actual unit for explanation purposes. Please click on this link for further reference---

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

I have a Pioneer XC-F10 Stereo CD Tuner. I keep trying to turn it on and it keeps turning off immediately...?


I Have managed to solve my instant turning off fault. As its been mentioned before, this is a demo mode fault, heres what I did...

Leave the Unit in standby, and press and hold the "system menu" button you should see the words "demo mode" flash up on the display briefly, at this point press the "set" button to enter demo mode selection finally press the "+" or "-" button to turn the demo mode off.

You have to be quick with the remote buttons when getting into the demo mode, might take a few trys.

I'm not sure if this will fix everyones fault, but certainly helped with mine. Good Luck.

Onkyo TX-SR805


When you turn up the volume, the amp works harder and generates more heat. There is a small transistor attached to the heat sink that detects the excessive heat and shuts down the amp before there is damage. There is a circuit inside that should detect the increased volume and turn on the fans. Either this detection circuit is defective or the fan driver transistor is defective. This unit may need to see a servicer. In the meantime, you can provide additional air flow to keep the heatsinks working efficiently. Realize that this is a short term "fix" and you should really get this repaired ASAP to prevent permanent damage to the amp components.

Whenever I turn receiver on, it turns off almost immediately


The amplifier blew out (probably shorted and damaged when wire was loose, and gave out under load). It won't be cheap to repair....
