I have an RX-V2400 and another RX-V I can’t remember the model number at the moment. Both have very dim VFD displays. Both have been factory reset with no change. This seems like a common issue. Lots of talk about possible bad caps but I’ve never actually heard of anyone fixing the problem. Is it just bad caps or something else? Thanks!

I have an old Yamaha RX V675 receiver which is starting to develop issues with the sound, although it doesn't quite match up with what folk normally report with these.
From cold, the sound cuts in and out. When this happens the amp is losing sync with the optical input (speaker graphic disappears from the front panel). But this is not resolved by putting the unit into pure direct mode. After a couple of minutes this resolves, although there are occasional clicks from the speakers after that.

Hi.
I have an old YAMAHA CLP-550 without sound. (Some times I can get some kind of noise or distorted sound)
I have replaced all green marked elements, but it gave me nothing.
The IC12 chip LC9116A-105 (red marked) remains under suspicion yet.

Maybe somebody came across with the same issue?
Any information will be very useful. I will be very appreciated.
Thank you.... -

Help Needed: Yamaha RX-V485 Network Issue After Firmware Update (WN9711 Error)
Hi everyone,
I'm facing an issue with my Yamaha RX-V485 receiver. During a firmware update, the process failed, and now the USB, Bluetooth, and network functionalities are not working. Occasionally, the receiver displays the error code WN9711.
I came across Yamaha Technical Bulletin No. 0103, which describes a similar issue for models like the RX-V4A, RX-V6A, and RX-A2A. According to the bulletin, the issue can be resolved by shorting soldering points (e.g., J260 for RX-V4A or...
