  • Lowrey LX510 Going Blank

    My Lowrey LX510 starts loosing playing some of the stops that are set, then progresses to latching the last notes it will recognize, then progresses to loosing all the set tabs and the display, then the first couple of times went into a reset, but the last time wouldn't reset by itself / with the reset button / or by cycling power. This has happened 3 times, after playing it for the first time about an hour (auto reset), the second time after about 40 minutes (auto reset) and the third time after about 40 minutes (wouldn't reset). The last time it happened as the church service was to start, and it had reset itself by the time the service was over.
    Any ideas of what may correct this issue?

    I'd suspect the power supply, and also internal connectors. The organ is 20+ years old, but it's fundamentally Japanese in terms of its components etc (Kawai own Lowrey and virtually everything inside comes from them) so its power supply should be OK, but we are hearing of problems with Yamahas of similar age, so it's a possibility. This is probably a job for a professional. He'd need to check out all the voltages coming from the power supply and trace them to make sure they're getting to the right places. He'd also check for problems with electrolytic capacitors.

    Internal connectors are always worth checking, as they can oxidise or tarnish. Unplugging, cleaning and reseating all the internal plugs and sockets can cure many ills but it's not a universal panacea. It's a job that, if done carefully, can be done by the owner.

    If it's a problem with the main board, I have a nasty feeling that the problem may be terminal, as there are, as far as I'm aware, few spares available for older models.

    With a complex organ like this, it's often time to call in the professionals.

      Thank you. I had to work connectors on a D500 until it died. Getting a professional to where I am will be hard so will try the connections route first. Organ was built in 1995, how long are components typically available after manufacture?

        Main boards will often be supported for around 10 years, maybe a little longer for some makes. Regular components like capacitors etc should always be available. Things like ribbon cables and other custom parts - maybe a few years after production stops.

          Wiping the connector connections solved the problem. It also caused Bb to be lost on the pedals, but this ended up being the spring of the contact coming off the rubber seat it sat on to make the contact when the pedal raised it. While I was at it I took Rodddiehl's recommendations in the Lowrey Majesty Pedals post here and cleaned up the pedal contacts so that they made consistent contact when pressed. Thanks for the help.

            Good to hear that you've got it all sorted! :)
