Power plugs do not come to the demo what the reason is on the display, how to solve it

Mr. Anderson

The reason the Sony HCD-GRX8 does not enter demo mode could be related to the DEMO-CHANGE signal. According to the context, the DEMO-CHANGE signal input is connected to ground to select the DEMO H/L state.

To resolve the issue, check if the DEMO-CHANGE input is properly grounded. If it is not, connect it to ground to enable the demo mode.
