    I post a query under the title Faint display on Aiwa Tuner

    The same was on the Aiwa Z9300 or a similar model.

    Thanks to Edd's 73's, among others, he was able to solve his problem with the Aiwa tuner display.

    I have a very similar equipment, the Aiwa Z-D8100M, to which the display of the GE-Z9100 graphics equalizer does not work.
    Also a very low 60hz hum is heard from the speakers
    I would like to know if there is also a solution for this problem, thanks.

    I soldered a couple of new capacitors into the ECB. It helped but it was still a bit faint.

    Thanks for answering.
    I forgot to clarify that the 50 HZ hum appears when the equipment graphic equalizer module is connected, code GE-Z9100M, if it is disconnected the hum disappears and the equipment works correctly.
    In the equalizer module does not work the display, it is completely off, but the part of the keyboard that selects the equalization if it works.
