Default Re: Freeview box with a modulator

One of my MFR200s seemed to suffer a modulator failure recently. RF passthrough continued to work, the front LEDs still behaved normally, and it would still respond to the remote control, but the modulator wouldn't transmit anything on any channel.

It turned out that the power supply was at fault, dropping to around 3V on load. So if you suddenly lose all modulated output, check the PSU first.

The original PSU is rated at 5.3V 1A, but a standard 5V 1A switched-mode PSU from CPC seems to work OK.
