Elfelejtettem megköszönni , de most bepótolom. Nagyon szépen köszönöm a javítást!!! Ez is tökéletes lett , mint eddig minden.
Ezt is szívesen, mi lesz a sorsa eladás-megtartás mert az előlapot lehet cserélni újra szokott lenni egy ismerősöm ezzel foglalkozik, most 350-es nincs neki, ezek mind újak dobozos és nagyon olcsó. Én is köszönöm a munkát.
@@HIFISTEREOLaca Valószínüleg előbb-utóbb eladás lesz a vége, de még nem most. Ha lenne hozzá olcsón előlap, arra még beruháznék szívesen. Mert most már tényleg olyan mintha új lenne.
A Philips erősítővel sikerült valamit kezdeni?
So clever. My Yamaha model is RX-V377X. The light does not turn on. I could used your assistance to repair my AVR.
Hello. Some supply voltage is missing, therefore the device is disabled, this is the most likely and the voltages must be checked after the service manual. But sometimes a contact error or a soldering error also happens, you have to check it carefully.
You have done a very good job. How you have repaired the DSP board? What you have replaced?
Thank you for liking this amp, maybe it was wet or stored in a damp place because there were signs of oxidation in many places and a lot of soldering needed to be repaired, especially where it oxidized. According to the service manual, the voltages must be measured, I don't know what is wrong with your amplifier?

I have an RX-V340 with no sound issue, and an RX-V371 with internal short-circuit on 3,3V supply pin. Both boards are looking good, no signs of oxidation. I will try to re-done all solderings to the 340 unit. For the other one need a new DSP processor.
I have this model bought in 2002, same dust inside. I have no courage to clean up but I'll try some day.
Good luck for that
Hi! Good job! A lot of work. The result is great. Beautiful amp. The sound in stereo mode without subwoofer is good?
Thanks.
Witam świetna robota 🤝👏👏👏👍👍👋👋jakiego silikonu urzywałes do konserwacji pcb?
Kontakt Chemie SILICONE 72

i have this model, is powering off after 1.5 sec
maby have any solution?
This can be due to a lot of soldering or ribbon cable oxidation, but mainly the power supply should look for the fault mainly capacitive losing capacitor, service manual should be downloaded and then voltages measured. These Yamaha home theater amplifiers have a type of fault directly at the incoming part of the mains cable, a 22nf / 630V foil capacitor is usually capacitive to voltage, but yours turns on and turns off after a few seconds because it has no voltage.
Which no longer turns on is the fault of the 22nf / 630V foil capacitor. Sorry but I wrote with a compiler but the point is understandable.
Can't find this capacitor 22nf,630v
@@rafaelyusufov9325 Yes, I have already written this, there is no 22nf / 630V capacitor in the RX-V350, so this error may not be in your device, in that case the amplifier would not be plugged in anymore, but these were the same and had to be replaced and improved, . the RX-V450 is already in. The voltages in your amplifier need to be blown away because they are not somewhere, but in the worst case, the STK power amplifier IC can also be a rare case.
