    I sure hope someone can give me some help!

    I own a "vintage" SONY XE-700 graphic equalizer which I absolutely LOVE. Unfortunately after having it installed recently in my car, the display has some lights which stay on constantly.

    My online search for a replacement display (Sony part# SON180857511)have come up empty, because but they are now discontinued.

    Can anyone repair this unit, or does any repair facility have a spare display laying around gathering dust???
    Or maybe how to "fix" this problem?

    Any help appreciated!

    Hi Gary and welcome to Electronics Point :)

    I can't find a service manual for this product for free download. There are dozens of hits for CDP-XE-700 which is a home audio CD player, but not for the XE-700. There is one available at http://www.abebooks.com/Sony-Stereo-Graphic-Equalizer-XE-700-Service/10103412726/bd for USD 20. If you buy it, scan it, and upload it to a file sharing site, we may be able to help.

    The problem could be caused by a failed display but it might also be a failed driver IC, which might be easier to replace. If you can take some photos of the circuitry around the display and upload them attached to a post, we may be able to tell something from them.

    Kris,

    That's AWESOME! I am in the process of purchasing the manual from the AbeBooks seller. (Asking if they accept PayPal)

    The only problem I see? When it comes to ELECTRONICS, I'm "dumb as a rock"! LOL That's the whole reason behind searching out smart people on this forum.

    I truly appreciate your willingness to help. It goes to show that there are still terrific people out there!

    I will be in touch, my friend.
