Hi,
my DVB-S FF card broke down those days. I think it's the tuner of the card, because it can't lock to a frequency: ----- Output of femon ----- using '/dev/dvb/adapter0/frontend0' FE: Philips TDA8083 DVB-S (SAT) status 01 | signal 6363 | snr 1919 | ber 080484c0 | unc bfc2d9f8 | ----- End of output -----
Additional I've a DVB-S budget card in the system. So is it possible to use the Tuner of the buget card and use the broken FF card only as display device and tell the system not to use the broken tuner?
Thanks and greets Patrick

You could insert the lines
if (IsPrimrayDevice()) return false;
at the beginning of cDvbDevice::ProvidesSource().

Cool. Works great (except for some distortions for the first two seconds when switching the channels, but this is ok for me :-) [I still use VDR 1.5.18]
Thanks a lot Patrick
I and some of my friends had same problem with ff card (rev.1.3) after 5-6 years. And replaced LNBP chip (located near bigest capacitor), now everything work as used to be. Total cost of repair was 10 euros ;)
cedo
P.S. It dosen't meen that you have the same problem as I, but you could try.

Ah cool. I've also a rev. 1.3 so I will try to do the same :-) Can you give me the part-number of that chip. Where did you get it?
So This is the power supply for the LNB and creates the different voltages and frequencies telling which band and H/V is required. Can I test the actual output with an oszilloscope? You know which signals must be there when in low/high-band and H/V?
Greets and thank you Patrick
I've get it from http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=497-834... About the oszilloscope and signals, sorry but I don't know... Hope that you will fix your card soon, cedo

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.

Yes, exactly.

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.
Cheers, Christian

Ah ok :-) so I'll see what i can do :-)

Ok my Voltage was 0V when it should be 13V and a sawtooth like voltage aroud 14V-19V
Thanks Patrick
