Not only do we get to see some great repair videos, but he ALWAYS plays AWESOME music also. Classic Rock, can't beat it! :)

Good job. This one was a little bit deeper than usual. I love the great close up work that you do these days since the new camera came in. Nice.

Great video! Love how things are explained and providing reasons why you go through specific tests.

FINALLY I have a s700w with the same symptoms. and the guts look similar enough for me to use this as a guide to troubleshoot. Been looking for info sporadically since last summer, and finally stumbled upon this one. Thanks for the upload!

I had a AVR-x2200w that did the same. Right when it would say “main zone on” it would switch off. I found a manual online and found “protection disable” mode and tried it. It’s been working great for a long time. Although I should probably not run it in that mode being that if something goes wrong I may end up with fried components

That sweet music of awesome troubleshooting!

Awesome video. Exactly the problem I have on my Denon 4300h. I will not try to fix it, but will contact you to ship you the Unit. Thanks

This guy is a treasure.

wow. im not even repairing a unit and still enjoyed it. lol

Good job steve

I saw you were jumping the pins on the plug while adjusting the BIAS but, I didn't see where the multimeter was hooked up too. Probably a dumb question but I'm still learning. Could you tell me where that was? I assume it was on the channel output terminals

you do nice work on these "how to" videos, thanks.

Is there a place that repairs Marantz AV receivers on the East Coast?

My question is why did the resistors blow ? Or ANY of the other parts. Not impressed for 4 yrs. old and a High-End brand. Upon further listening to video , DO NOT let customer hook up those speakers😍 Sounds like they damaged something. Really interested to see the WHY this happened. That video will be a doozy.

I like your mind!

Really good explanation. I have the same unit mine seems like everything works well ( video, setting, internet etc) except that is no sound on any of the speakers? By any chance have you encounter something like this issue before? Thanks!!

Have a similar problem with a marantz 1504 receiver, stuck in standy, have to bypass stanby for the unit to work, that is what my technician advise me to do as he could not seem to find the fault.

Hello everyone, I'm repairing a Denon AVR-1509 amplifier, I can't find the specifications of the D534 diode anywhere, I know it's an AX52 diode, but what kind of diode is it, what specification, what specification? Please help

Nice

Do you have any video on how to change the main screen, it suffers from color wear, DENON AVR X-4300H

Hey what causes this thing to fail is it not giving proper heat Dissipation or what is federal aid or what is your opinion of Y stereo's fail like this?? Please let me know thank you

You mentioned the blue bodied resistors are flameproof. What do the green bodied resistors indicate?

Hi, I have a 4200w with the same issue. I've identified 2 or 3 resistors that have blown, but I'm having trouble working out if the transistors are OK. It seems going red to the middle and black to the outer legs works for every other transistor. Then for the ones between I go black to middle and red to outer and I get a 490 to 620 reading ( same as the others with switched leads) does this mean they're OK and just every other transistor is soldered differently or that every other transistor is broken?

Pioneer LX76 no tienes vídeo de reparación?

My DENON AVR-X4300H did this today, smoke / smell came from the middle and then I got this same problem.

Hi sir i think my denon receiver same problem. I want to send mine for repair

I've Denon 4311ci it shows DSP 01 error no audio out (analog and HDMI I/P), rest of the things working fine how to fix this? Please help me...

hello sir how much do you charge for work like that , because were i live(israel) most of the people just buy a new set and not repairing anything . thank you

I have denon avr 1200w it's gone on the protection mode checked all the transistor it's ok what can we check further please help

Hola buenas noche

Having the schematic solves half the problem.

my X2400w had this issue last night, and I'm going to attempt the repair based on this guide. For the current configuration at the end across the bias, how are you testing for 8 mv? One probe to ground, and then it looks like you've split the red probe across two alligator clips?

I need your help. My AVR 4200 is in protect mode. Can I send you my unit ?

Hello. I have a lg dvd-vhs combo vcr. The first 10-15 minutes show bad. Then it gets better. I tried many different cassettes same problem. I wonder what the problem might be. Sorry google translation

Good repair Sir. I have a Question : When making amplifier based on TDA 7294, only thermal compound is enough or mica/thermal pad should also be used?

Awesome video. I just got a non working X3300 from my parents who ordered a new AVR. This one is doing the same blinking red light. My results are almost identical to yours. I have 2 transistors that are testing bad as well as 2 of the larger resistors and 2 smaller resistors. I am going to try and order some replacement parts to try to repair this. Where do you order your parts from?

Hi, I have blink red light standby for my Denon AVR 4800. I am also in Norcal, but not sure how close to you. Would you be able to take a look at and hopefully fix it for a fee? I like my Denon but this blinking standby light is eating me up.

Did the speaker cause the problem ?

hello great video , i have similar issue , with X2700h , my reciever working sometimes 1 minute , sometime 30-40min and turn off in protect . When i go in developer mod say “DC” is displayed (DC output of the power amplifier is abnormal. If the power is turned on during this abnormality, protection is activated after around 6 seconds and the power is turned off) is it the same problem ?

I have a x3400h doing the same thing and would like to know what would a repair like this costs? Im severely disappointed because I don’t use it very much.

Hi. I got the same problem on my AVR as well. But after I replace the bad transistors and resisters, the unit stays on for about 5-10 minutes and shut off as DC protection again. And it can work probably after reboot for about 5 minutes again! What will be the potential problems?

I brought Denon avr 1804 receiver not working( red light blinking) I Changed the two regulater icies 7915 and 7815.when the turn on receiver then suddenly come noice and smoke that changed regulater area. Now again red blinking 😔 Want to do.

I have a x4500 where the subwoofer pre out stays silent because of a lightning strike. Everything else works fine though and device powers on. Any idea on what I could try? I don't want to throw it away quiet yet.

Hi. I got a chance to buy used Denon AVR-S930H Receiver (what price worth to buy? I'm worry if Denon won't keep up with Yamaha even with Atmos-DTS-X features. Features are good but more important is sound quality. Should i stick with Yamaha and look for newer models? Will Onkyo do better job too compared to Denon? I heard Denon's are cheaper and less reliable compared to Yamaha and Onkyo. Any opinion? Thanks.

Hi @NorCal715 and happy new 2021!! I have a problem with my AVR-S940H and maybe you can help me. Everything work fine except the analog tuner (AM/FM). I tried all of the steps but nothing solve the issue (factory reset, firmware update, reconnect fm/am antenna, unplug/plug speakers, source seletct in Zone2, etc..) The specific problem is.... the automatic serch is in loop, never detect any station (AM/FM), if I put manualy station, I can't ear nothing. No radio station, no static noise, nothing. Im lost, you have any idea? Tks. Btw. I have the service manual but the tuner section is very poor for diagnostics.

I have an x4500h which turns on but ok the screen the outputspeakers do not show and there is no sound output from the receiver, help I'm stuck

I used your video to test and repair a Denon avr-x1300w. it was almost identical problem. I am just a novice hobbiest. Can you tell me why when I get to the bias adjustment, it is reading 187mv when other channels are reading 2.4-2.8? I replaced D2390 65 P, B1560 65 P, qty 2 - 4.7ohm and qty 2 - .47ohm resistors. The unit powers on now! only thing different I can see on the parts I replaced is the D2390 has a 54 P instead of 65 P, same with the B1560 has a 54 P instead of a 65 P. Will that cause the bias to be so far off?

A real tech is like ihens teeth ! l ran this avr on one channel like a banana ......plug came out and a terrible smell ensured followed by protection warning that isn't going away . What say you sir is it a [denon avr 2000 over driven ,] look for a bbq transistors or ic in the output or chuck it ?

Does it really matter if the numbers on last line on transistors like 79 Y, 4N Y are different on replacement transistor..? i found a replacement transistor B2650 15 P instead of D2560 4N Y . Is it Ok to use it?

Hey can you help me with my avr-x4200w

I have the same problem with my denon avr-785, do you can help me?

Hi Norcal715 I have a Denon 2311CI, makes a noise a left channel, what a can be?

This video should be titled "Denon receivers are junk, don't buy them". I bought a S540BT just over two years ago and this started happening. Apparently, this is super common with these POSs. And this crap thing didn't even put out decent sound.

Hotel California! Yeah. Fantastic video. Thank you. I see you are NorCal. Me2. I am looking to purchase the exact same amp on Craigslist. Would you be willing to repair mine please? Ping me and I will contact you for the unit.

can you help me fix my 4200?

What is the reason that would have caused this problem?

Hi Norcal. I have a Denon AVRS 930H Receiver. It has same issue that the power light comes on and shuts down the unit in 3-5 seconds. It would be helpful, if you can guide me to repair it. I have good soldering skills and have soldered some stuff before. I am living in India. I imported this unit from US. So I have been using a Stepdown Transformer from 220V to 110V.

Where are you located and what do you charge?

Can you repair mine, Where are you located,

Do u do repairs

But once you open up a Denon receiver you open up a can of worms because there are a million and one jacks that you have to disconnect and 30 million screws and you don't have any access to the bottom so you have to take everything out of the case in order to service it just like all the modern receivers these companies have screwed the service techs it's not like the vintage equipment you can open up the bottom and get access to the circuit board all this new stuff you got to rip it completely apart in order to service it and then if you get a service contract with these people they want you to do it for peanuts that's why a lot of technicians don't want to do service contracts with these companies because they want you to do it for next to nothing there and then when people complain that they don't have their equipment back it's because the companies have not sent the parts and the parts have not been made yet and I think it's the technicians fault want to new receiver goes down 9 times out of 10 when you bring it to the technician to be fixed the technician is waiting for the parts and the reason why he's waiting for the parts it's because the company has not produced them yet you tried to tell the customer that and the customer doesn't want to hear it they want their stuff now and then when I usually do with that turn around when I tell them I'll put it back together I'll hand it to you and then you go fight with the company the only thing I can do is order the parts if the parts are not available I have to wait until they are you call up the company and you yell at them don't yell at me yell at them

To hell with all of that! I thought this guy was going to show an easy fix. I am NOT about to take my receiver apart and attempt to do anything with it internally because, I'm not a technician and I don't have the testing equipment that's needed, nor the knowledge to do it. I'll take it to a certified repair shop and get an estimate. If it costs too much, then I'll just buy a new one. This guy is obviously a tech geek, a professional who has the experience and the knowledge to repair electronics. It's not for the novice, so I'll leave it to a professional who knows what they're doing. A person can't learn to perform a brain or a heart surgery from watching KZfaq videos! You'll have to go to Med school and study for numerous years to become a medical specialist.

I have a AVR-X4700H that i got in 2020 that has the same rlinking red light
