In Germany, you can get it from Segor:
Because of their pretty high "Mindestbestellwert", people often buy more
chips then actually needed to fix their FF cards. So it might be a good
idea to ask/search on vdr-portal or offer the spare ones there.

Usually, you won't even need an oszilloscope to detect failure of the
LNBP on the Rev1.3. With a dead chip, the LNB supply voltage is missing
or way to low in almost all cases.
If VDR is tuned to a transponder with vertical polarization, you should
see 13V supply on the connector. With horizontal polarization, it should
