Yamaha RX-E810 repair #2

First a failure occur and then after repair a 2nd issue will come. Look at this obscure situation on this Video. I must say I've sometimes things like that but this is not normal. Please subscribe. Be a part of this obscure situation and the bad. Have fun to watch and Thank you for watching! weakbit

I repair the power-supply and then the receiver worked for 3 times but then incidentally the µController newer worked in case there is stopping the 16MHz oscillator and the 32kHz Clock for the watch is also not running. VCC 5V is available on Pin 62 & Pin 16 at IC200. Pin13 XTALout and Pin15 XTALin is no oscillation anymore - so what can I do with this defect?

Hello man! Tank you for your great video! I have exactly the same problem with the same unit. I changed capacitor C8 which looses capacitance (22 nanofarred 630 volts) and it turned on. I was really happy (just like you on this video). Then I turned the unit off and connected the loudspeakers. After that, I turned it on again and synthnized a radio station. Everything was perfect for 2 minutes. Then it suddenly turned off with a click sound. Probably there is some kind of protection that activates when speakers are connected. Definitely we need to find the solution to this problem since it is a great unit! Fernando from Mallorca.

The problem seems to be that capacitor C8 (the one I mentioned in my previous post) looses capacitance and cuts the negative power of this main supply unit. Investigate on that and let me know!

Normalis the C8 defect and this supply the flipflip.

Tradu text folosind camera foto greetings from Romania. i have watched your videos hundreds of times....my yamaha 810 won't turn on. I changed the 22uf capacitor but nothing. I don't have a k3850 and I can't find a close equivalent. I made contact between the relay pins on the 230 volt side and the surprise starts after I press the start button. I removed the relay, measured it and the coil is broken. I listened to music like this for hours at a moderate volume and it still works. My question for you is: after measuring the relay power point why do I have 10.4 volts only for 2 seconds when I press the start button then 0 volts? I specify that it still works very well, only that it must be removed from the power socket. I am waiting for an answer. Greetings
