    CA600 Yamaha amp LED/BULB help please

    Hi all

    Have replaced output devices for one of the channels & amp now working, but a previous explorer has decided to rip out the power on indicator LED/BULB.

    Not a clue what type it is, or even where it's connected.

    Can anyone help.

      It is a 12v 60ma Lamp, connects to pins 5 & 6 on power switch board.

                  Connected to pins 5 & 6 of the main on/off switch PCB, which are the top 2 tags.

                  Used a pilot light bulb from an old VCR deck as I'm fairly sure they were 12V.

                      if by pilot you mean the post lamp that sticks up into the tape and detects the start/end leaders then perfect - if you can find them anymore!

                          Hi STJ,yes from the old Ferguson 3V29 model VCR machines that were very popular once upon a time in the UK.

                              TOSHIBA DLP 52HM95 How to reset timer module on bulb
                              by repair-it
                              I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

                              Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...

                              LUMIMAN Smart Bulb IC ID?
                              by ezenia
                              Hi,

                              I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.

                              In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting...

                              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...

                              Replacing incandescent bulb on Pioneer LD player with led. Need help :)
                              by JimBanville
                              I have a pioneer dvl-909 LD/dvd player from 1998. It has a light on the front panel that lights up when you play a dvd. I removed the bulb and it appears to be a tiny incandescent bulb. Its measures "open"/dead and the bulb is black like it's blown. The socket it fits into measures 5v. I've looked up the schematics and there's no indication of the amperage. I don't want to spend any money on new parts, but I have a pack of like 100, 3v, 20ma LEDs and I have various resistors.
                              Is there a way for me to determine the amperage going to the old dead bulb with my multimeter?
                              ...

                              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...
