ROLAND SYSTEM 1M LED DEMO VEGAS MODE NOT WORKING

[wleader]

Hello all
I have a Roland system 1m that I purched from a person on Reverb My Roland system 1m led demo or what people call it (vegas mode) is not turning on I reset it to go on in 2 minuets but it does not work can you help ps this is the process i took LED DEMO: Hold down the [LPF TYPE] and turn the [SELECT] knob. Specifies the time (minute) until the LED DEMO is shown (PITCH ENV (IN) jack lit means +10). If this is set to “–,“ the LED DEMO is not shown. I set the 1m to all different times 1-9 does not turn on please help. I think led demo mode is broke I tried doing a factory reset nothing is working I love the green lights lol
