The ABC would like to advise that upgrade works will be undertaken between 2am and 4am on Thursday 21 August on the Perth metropolitan digital television service. These works are designed to resolve problems some viewers are experiencing when watching ABC1 on LCN 21.
The changes may affect reception on some set top boxes and PC tuners using PID selection. In these cases, viewers may need to simply power their equipment off and back on, although for some viewers, a channel rescan may be required.
The ABC apologises for the inconvenience.
