    Yamaha Bluray players

    Got two Yamaha blueray players to check (they were going to e-waste), the other don't start at all (bulged caps in the PSU) and the upper one starts but the display is very dim. Which one is better unit?Click image for larger version

    Well start with replacing all the bulging caps, inspect the rest of the caps, they should be absolutely flat, a flat one can be bad too but any bulge or leak out the bottom and it's bad for sure. A lot of times a bad cap/s is the only problem, replace and try it.

      If the question is asked which one is better, higher class and more expensive, then this is the A1060 model.

        The dim display could be caused by weak capacitor/s on the powerboard. This is where a capacitor meter would be handy, some multimeters can test capacitors if equipped with that function. The display could also just be wore out.

          Need to chech the PSU, the other (non-powering) unit has one bulged cap. The display is not certainly not worn out, as these were used almost never. Blu ray is an obsolete format in a school auditorium.

            Well replace that one cap, might be the whole problem. Electrolytic caps may last a long time but 10 years is an average lifespan, so replacing all of them would probably not be overkill.

                    No bulged caps in the unit with the dim display. All voltages are ok.

                      You rather have the brightness of the display reduced; you can turn it on using the remote control and pressing the “DIMMER” button.

                          That's a possibility, I see the remotes on ebay U.S. for about 10-15 dollars but that's pretty far from Finland, maybe you have some nearby.

                            I have a remote, but it does not have the dimmer button. Maybe it's for the other unit? BDP122 is the model. Works with the A1020.
                            A1060 has no -25V voltage to the display unit, 12 and 5 volts are ok.

                              On the original remote control from (A1060) there is a DIMMER button

                                I'm not clear which one has the dim display, you mentioned the top one so I thought it was the A1020 with the dim display.

                                  The A1060 is not powering on, I measured the PSU and others are ok but the -24V to the front panel is missing. Hard to do anything without the PSU schematic.

                                      Dark one is the dead board from the A1060, white is the working from the A1020.

                                        Try something simple, sometimes heating the electrolytic caps will bring a marginal/bad cap back into specs and the device will work if only for a bit. Heat all the electrolytic caps with a hairdryer for a couple minutes and try the player, don't wait til it cools off, try to work it while they're still hot. Check the solder joints on the bottom, make sure none are bad, search for images of bad joints if needed.

                                          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...

                                          Yamaha RX V675 sound issues
                                          by jjne
                                          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...

                                          YAMAHA CLP-550 without of sound

                                          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.

                                          But it is custom YAMAHA's chip, and I can't find any information about it.
                                          Maybe somebody came across with the same issue?
                                          Any information will be very useful. I will be very appreciated.
                                          Thank you....

                                          Greetings!

                                          It has been very long time that I opened up my garage again because I got something that I could not stop myself and this time I have a Yamaha RX-A1020 super powerful (at least from inside structure 😉 ) AV receiver. When this unit came to me this Saturday it was full of dust and what not but the standby LED blinked when pressed and power relay clicked once but no display. It worked 3 times after normal reset like other Yamaha receivers and then again it had to be unplugged to get his behavior back. I opened everything and cleaned it up and...

                                          My friends Yamaha RXv-485 receiver has stopped communicating on network and Bluetooth, we decided to make a firmware update from USB stick but after a while it comes up with the message "unknown".... Its the latest 1.87 version we are trying to load and it seems like the is no firmware in it at the moment as it does not state the old version ?

                                          Any ideas how to resolve this issue?​
