    Tivoli Music System+ no backlight on display resolved

    Just had a Tivoli Music System+ without any led backlight display it turned out to be a variable 100k pot had gone open circuit on the variable leg on the pot!
    I haven't seen any information out there on the internet regarding these units so thought it would help others in there search for resolving it!
    The hot glue over time I guess which was all over it before I pulled it out had caused the issue with time.
    The unit uses 3V leds behind the lcd display to illuminate it together with a photoelectric sensor to adjust the light output for the light intensity of the leds. This 100k resistor was part of this circuit for the photoelectric sensor.
    See the attached picture where the 100k resistor has been removed. I have circled the position of the 100k resistor for anyone interested on the pcb's.
    Good luck with your repair
