There is a known problem and outstanding AD (airworthiness directive) regarding some Honeywell transponders: http://www.tdatacorp.com/iaprch/06-19-04.htm

If you're not quick enough in changing the code, the unit drops into SBY. It would come back on-line as soon as they (quickly) dialed 7700 which I imagine they did after the collision.
(Disclaimer: I fon't know if this particular airplane had this model XPDR.)

Do not believe everything in the media, whatever their nationality.
