Hello, My name is Michael glad you managed to fix it, i have Denon AVR-2312 which is dead, i have checked the voltages there is 5.2 volts coming from the SMPS to the HDMI board, i have seen 5v going to the input of all the DC to DC converter IC but there is no output, i have the schematic of the same, would appreciate if you could guide me on this.

I am glad to have read your article. I just took possession of a Marantz SR5005 receiver with the same board, same power problem. The 1.6A fused on 1st attempt. I noted that the SMPS Board was not clean. Some staining. Took out most diodes and Zener diodes and found some IN4007 faulty just like you described. Cleaned up the board, got most parts online, arrived but the TOP256 came as a PG version (7 pin), my error. Now, I wasn't so sure if the TOP258MG can be reused cos it looked ok. What is your opinion? Tqvm for your advice.

hi.
My Denon 2311 actually has an issue with the POWER. Searching the net, I came across this!!!
We discovered that Large Capacitor is blown, exploded!! Maybe the IC next to that, some other neighboring Diodes etc too..
What Model / Capacity is that Capacitor, does that have a name, number?
Is that costly? As well as that IC - Top258MG?
Thanks again!
Warm regards,
George

Hi Raj,
I have same issue on AVR-2311. My case is zener diode MTZJ22B were broken instead. But I can find same device in Singapore. Do you have any idea how to find these devices? I couldn't find it in Sim Lim.

Sorry for late reply.. Tied up with Covid measures at office. You mean IC: TOP258MG? I bought it locally in Singapore. You shall try at aliexpress.

Hi Raj,

Thank you so much for the article. I am based in South Africa and my AVR is experiencing the same problem and we do not have parts suppliers this side. I need the IC. Do you know where I can order this part for my AVR?

Your assistance will be higly appreciated

I have DENON AVR 1311 Red light blinks when switching on the amplifier and after 3 attempts it will go green and start working.

What could be the reason. and how it can be fixed.

Thanks
