Boeing confirmed to ZDNet Australia this afternoon that the issue does exist, but said that it has not delivered any planes suffering the fault.
"Blanking of the Phase 3 Display Units (DUs) has been reported during airline EMI (electromagnetic interference) certification testing of wireless broadband systems (Wi-Fi) on various Next-Generation 737 aeroplanes," Boeing told ZDNet Australia in a statement.
"Boeing has deferred the activation of wireless systems that interface with passenger devices that could potentially interfere with the DU 3 displays," it added.

A senior Boeing engineer stressed to ZDNet Australia that the levels of EMI required to affect a pilot's screen exceeds the levels produced by the normal operation of normal levels of Wi-Fi use.
"Boeing and Honeywell have concluded that actual EMI levels experienced during a flight where there is normal operation of a Wi-Fi system will not cause any blanking of a Phase 3 display. This is not a safety issue with currently operating 737s and 777s," a Boeing engineer said.

So this is a problem with
wifi delivery systems (aka, "in-flight wifi"), not wifi devices that just happen to have their radios on, and does not happen at normal operating levels. There's nothing a
passenger can do to cause or stop this. It can only happen if the in-flight wifi is misconfigured and then turned on.
Or in other words, it's a red herring.
