Hi fellow members. Happy 2025. I have some SMD carbon resistors to replace on the Filter board but I don't know the package size to order. Anyone have any resistor replacement experience with this Yamaha small PA system? Thanks!

I have a Yamaha Stagepas 300 PA system with the left channel out. There are separate power inputs to each Power Amplifier. I repaired the left channel amplifier so both work. However, I still have no left channel output to speaker. Both speakers are good. I have a multimeter and an old Radio Shack signal tracer for troubleshooting and that's it. I checked all voltage inputs to both amps and they match. Don't know how to proceed to check or trace signals or voltages at amp outputs BEFORE they go to speakers. Any help appreciated. Thanks in advance, Dave -

Hi everyone,
Looking for some advice or opinions on what to do with a monitor issue I’ve run into. Apologies in advance is this crossovers a few forum categories.
I have a Dell U3425WE, which I've recently replaced with another model. That said, the original unit is still fully functional in terms of the display — it works perfectly over HDMI and DisplayPort. However, the USB-C and Thunderbolt 4 ports have stopped functioning correctly. The Issue:- The 90W Thunderbolt 4 port (circled in the photo) no longer charges or powers any device, including laptops or MacBooks.

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... -
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.
At first I thought it was either a speaker relay or the DSP, but I don't think...
