Very ugly repair! SMD caps should be replaced by SMD caps. The through hole caps you used are also "aluminium" type and electrolitic. They don't loose power but capacity (here in microFarads). However, this gave me an idea and I'll try it on my ONKYO TX-NR616.

No, that's wrong. If you want to have the same problem again in a few years, then replace the SMD components with SMD components. In the meantime, google planned obsolescence. Unfortunately, you have no idea.

​@@RepairUpgrade, let me show the obvious here: 1. The SMD caps you removed are the same type as those you placed: electrolitic polarized capacitor in an aluminum capsule. The ONLY difference is the way the component is fixed on the circuit board: SMD goes on the surface, hence the SMD - Surface Mounted Device, those you use are through hole components, classic way to mount them. Both types have specs as capacity (microFarads in this case), working voltage (from 3.3 to 63 Vdc for these sizes) and maximum working temperature, usually 85°C or 105°C). 2. The problem in these ONKYOs is the design flaw regarding the heat dissipation. These receivers will get very hot even if playing quietly or in standby. So, the electrolytic caps will eventually fail, no matter the type used: SMD/through hole, or even older tantalum type. 3. The repair shown here is unsafe and ugly. Dangerous because those long wires might twist or touch any part of the circuit nearby. Short-circuits and sparks everywhere! Since these caps are for filtering/decoupling the terminals are connected to ground and any of the powerlines in that device and this is dangerous. Also, the way you removed the failed caps by twisting and pulling instead of desoldering can damage the solder pads and circuit traces. So, who is wrong here?

very detailed & useful video Thank you!. I used your info to understand why my reciever shuts down - The reason shows up as VOLTAGE. History: I radomly get static noise out of any channels especially when there is no I/P signal & the volume is above 20. One day the Static noise came too high & it has since gone to Protection mode and shutsdown. The intresting thing is that if i reset the receiver it would come back good for a few days and then the static reappears back(not restricted to any particular channel). I also lost a Tweeter due to this issue. Any idea where could the fault lie at ?

Wie messe ich mit der Einzeltriggerung ein 1maliges Ereignis ?: Nur Ch1 ist eingeschaltet und man hat zwischen Probe und Masse einen 1kOhm Widerstand, der zu nahezu Massepotenzial führt. Nun schließt man dazu eine 1.5V Batterie von Hand parallel. Ich möchte dieses 1malige Ereignis mit einem Triggerpegel bei 1.2V und der steigenden Flankentriggerung erfassen. Eigentlich ganz einfach, aber mir gelingt es nicht, weil die Triggerkonfiguration immer wieder nach AUTO oder NORMAL aus EINZELN herausspringt und ich das Ereignis nicht aufzeichnen kann. Es muss doch möglich sein dieses Ereignis auch im Bereich von usec aufzuzeichen, wobei man dann das natürliche Prellen bei der Kontaktierung mitmessen können sollte. Haben die Geräte hier einen Fehler oder ist die sehr dürftige Funktionsbeschreibung daran Schuld, es nicht ausführen zu können. Ich stehe davor das Gerät zurückzugeben.

Instead of opening up the receiver and soldering in the power supply cables, buy fans with USB power supply and plug them into either the USB power on the back of the receiver or an AC to USB transformer plug. Then just place the fans on top of the receiver. That is easiest and cheapest, plus it doesn't void your warranty.

Unfortunately, I didn't find any Service Manual in the net for my model and I can't find the correct capacitor to exchange and see if it fixes. Do you have the manual or someone else from a similar model or any other tip to handle this?

Hi. Ich hoffe, dass du noch aktiv bist :) Ich habe ein Problem mit meinem Onkyo AV-Receiver TX-NR636. Das Problem ist, dass ich mit meiner ps4 pro und ps5 erst Bild/Ton über hdmi bekomme, sobald ich den Quellenanschluss teste. Vorher bekomme ich gar kein Bild/Ton oder komische Bildfehler. Danach kann ich ca. 2,5 Stunden spielen und dann kommt es zu Bildfehlern und das Signal verschwindet komplett, bis ich wieder den Quellenanschluss teste. Dann kann ich wieder 15 Minuten spielen und danach verschwindet das Signal wieder. Bin mit meinem Latein am Ende und hoffe du kannst mir helfen. Lg

Hallo, wenn der Fehler im laufenden Betrieb auftreten würde, hätte ich auf ein Überhitzungsproblem getippt. Das hättest du einfach testen können, in dem du den Receiver ohne Gehäuse betreibst. Wenn der Fehler ohne Gehäuse nicht mehr auftritt, dann ist der Grund die Abwärme, die nicht abgeleitet werden kann. Du könntest das Problem dann mit einem Lüfter beheben … In deinem Fall gehe ich von einem (bereits) beschädigten Bauelement z.B. IC aus. versuche mal den Fehler auszulesen. Ich habe hierzu ein eigenes Video erstellt. Unmittelbar nach dem Start. Dann wenn das Gerät funktioniert und dann sobald die Fehler auftreten. Und dann Vergleichst du die Ergebnisse. Mit etwas Glück erhältst du Hinweis auf den defekten IC, der betroffen ist.

If I would to order the same capacitors would it work, or would I have to hunt down the wiring diagram to check ? I can solder, but from an electronics standpoint, that's about my limit.
