Red Blinking Power Indicator Denon Receiver AVR-488 - shuts off - won't stay on etc.FIX! 

Hey! Glad the fix worked for you on a different model.

YAY! Glad it worked for you.

I have the "red light blinking" issue with my AVR-1603 as well. Do you mean you replaced parts in yours to fix it? Which parts? Or did you just do the reset?

that's what I said in my comment I would take it in if my issue didn't solve .

Thanks for your comments!

Thank you!!! I was so disappointed I hadda go out tomorrow on my day off and buy all these supplies to fix my stereo. But your power button trick WORKED!!!

Did it fix it?

No update

+London Pinball No go. Replaced the two regulators and it did not solve the problem. This receiver may hit the river soon. The research continues...

+London Pinball Thankyou for updating us with your results! :) (I have the same issue)

+Zoloft, Montreal I never solved the problem and instead tossed the unit from a very tall building. No more problem!

Some times the output transistors go bad it can cause this too. I repaired a few with this problem

u can test them with a meter if u get volts in not out that your bad chip.

Glad this helped!

Jay G. What did they say the problem was n is it fixed and how

I paid $300 and a capacitor was shot on one channel. And oddly the other channels had loose capacitors too. I heard on one youtube site that these receivers had poor solder joints. Well after 17 years, I guess my solder joints cracked! But I'm a up and running now blowing the house down!

Jay G. Hood job. I am from london and bought one from a guy near my house. I bought a marantz sr6008 av. I saw it working at his house. When i brought it back to my house.. it turns on then off after few seconds. Seller wouldn't provide refund. I dont make much money and can't afford to get it fixed. Hate my life

Probably a capacitor or resistor came loose from a solder joint in transport. Easy fix if you can find someone that works on electronics. I'd recommend my man but he is in Dallas! Sorry to hear this but save your pounds, you can fix someday!

Jay G. Thanks jay.. you are a good man 👍🙄

Good Idea. .I paid already twice about $800 for a Denon Amplifier, and now the second one is dead too... So, this time it will be a normal cheaper brand...

Buy Marantz

A demon I mean a denon service tech who wanted to make $200 + dollars for this simple repair . 😂

Bill Flemming Good idea!

Bill Flemming Hi; If you are referring to the electrolytic capacitor(s) on the voltage regulator inputs, I would check them to make sure they have greater than 35 volt working voltage rating (marked on side of electrolytic capacitors), and for reverse installation. The tricky one is the electrolytic capacitor connected to the minus (-) 15 volt (7915) regulator. On this one, the positive (+) side goes to ground, and the minus (-) side goes to the regulator input (pin #2). This is how a polarized electrolytic capacitor is connected for negative voltages. Good luck.

Ralph Bonser Not sure why part of the text has a strikethrough. It is applicable. Thanks.

You must be in St. Louis?

databits Yes I am. My brother used to shop at Gateway in the 70's. Great place.

I have one of the popular X1200W models that has the blinking light. You have given me a good starting point to troubleshoot the error.

@@databits Same here....I was crushed to hear that Gateway Electronics has closed. :-(

Same. It’s so sad.

+anasazi09 - this is explained in the video, there aren't two smaller ones on the right

Francisco Goitia - Glad it worked for you!

I don't recall seeing any corrosion, just some black or brown discoloration on the circuit board.

Tom Elliott ... I have an 1801i recently picked up @ a thrift store for $ 14.99 . I reset mine using ( after going friggin nuts with all the buttons and videos), by pressing...Memory+ Mode+Power...At the same time,but release the power button 1st, when it changes on screen, release the mode/ memory buttons...mine says "Auto Preset"..blinks a few times then says ,"Completed". Check it out if you haven't figured it out yet. Peace...

Hey man same problem but avr-3801 don’t look the same. You think you could help me out

I don't know. Having been a consumer electronic repair tech. 40 or so years, when you have a foreign object fall into an uncovered, unprotected receiver (or anything for that matter) it can cause almost as much damage as a severe, direct lightning strike, providing it was powered up at the time. Unless you saw where the wire landed & saw anything spark, smoke, etc., it may have caused the same type of chain reaction damage a lightning hit can do. Basically, that means getting ahold of a ''good'' schematic diagram that shows the proper voltages in particular areas or circuits of the receiver so you can take voltage readings (you do have a good volt/ohm meter? I use a digital & analog both when troubleshooting) in areas the wire landed. If yours is completely dead (no blinking light), I'd check all the fuses you can find 1st. You might get lucky, find a blown 1, replace it & you're off & running again. I'd do that before trying to get that schematic. Otherwise, it's ''good'' schematic time. I've got an AVR-1609 that's blinking & I've just let it be for 2 or 3 years until I saw some helpful tips on here. Although I've read a lot of negative comments on here about it being made in China or other things, I really want to fix mine. It was a ''machine''. Not only was the sound quality was excellent, the video circuitry in this thing cleaned & sharpened up the picture on my TV (I still have the old CRT TVs) so much, I couldn't believe it. After having worked on so many ''shut down'' situations over the years, I've learned they're a real pill to work on since nearly any component in any circuit can cause a piece of equipment to go into shut down. I truly wish you all the luck in the world in your repair conquest. Hopefully, a popped fuse will get you going. Again, good luck & take care.

aamir khan start by looking at recycling center

Francisco Goitia I use my finger in the video to point to the transistors. Best I can do.

probsn - Yes, I am in St. Louis - can you message me?

Bri G. In my model, they are voltage regulators. In some models, they are indeed diodes.

If they have the numbers ''7815 or 7915'' on them, they should be 15 volt, 1amp voltage regulators. The 7815 being a 15 volt, 1amp positive voltage output regulator & the 7915 being a 15 volt, 1amp negative voltage output regulator. After having replaced so many 78'' '' & 79'' '' voltage regulators in the possibly 100s of satellite receivers & other types of equipment over the years, I became very familiar with these components. 1 thing to take note of or be aware of is, the pin out, or placement of the pins on these. The pin out is not the same with the with the 79's as it is with the 78's. If you're just replacing them in a circuit board, you shouldn't have to worry about this issue. If you're building a project, be aware of the pinout & pay attention to the way you wire them. They're very handy little parts to keep around. They're wonderful little voltage providers for projects or ideas you're experimenting with.

Time to purchase a new receiver?

I'm was thinking. .. but now it hasn't done t since so its still bumping on about 3 years strong.. well see thou hopefully doesn't mess up now, knock on wood aha . Cheers

No other suggestions other than what I include in this video. This was my only experience with a Denon. Good luck!

Okay thanks.

I do not, sorry!

Joshua's Recordings Probably not, but you can try it. Be sure to order exact replacement parts.

databits Never mind. It turns out that when I brought it home the speaker terminals got went. Now that I gave it a day to dry out it works perfectly!

databits good video you got here sir. I have the same problem with my pre-owned Kenwood Avoid surround receiver VVR-414 I bought. Do you know what reset method I could use before going through replacing parts? Thank you sir.

Joshua's Recordings I had similar problem: when replacing cables (unit was switched on) one of the cables disconnected from the speaker was lying on the floor and made a short cut circuit. I guess this red button regime is like a safe mode. Thanks!
