Hi Patrick, In Germany, you can get it from Segor: http://www.segor.de/suche.shtml?foto=0&Q=LNBP16&M=1 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. > So This is the power supply for the LNB and creates the different voltages > and frequencies telling which band and H/V is required. Yes, exactly. > Can I test the actual output with an oszilloscope? You know which signals > must be there when in low/high-band and H/V? 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 be 18V.
