Dead DVB-S module? Advice please..

[KrisW]

Hi,

At some point over the last week, my VU+Duo 2 stopped tuning on DVB-S. I don’t believe this is anything to do with the recent FreeSat renumbering, as I am unable to tune any service on any satellite.

Signal finder shows 0 dB for both Tuner A and Tuner B, and all indicators are zero. This leads me to believe there’s a hardware problem, not a dish misalignment or damaged cable - I have not called an installer out to test the dish yet, though. (DVB-T is still working perfectly, so if there’s a fault, it’s between the dish and the main system board).

Is there any way I diagnose if this is a dead tuner card?

Heavy rainfall in your area? Water in cable?

Check box in another location to see if it works there + F connectors are tight

Thanks.. It’s been unusually dry here, so probably not water ingress. I’ll bring the box to a neighbour’s house and try on their dish, but I

If it’s the module, what are my chances of getting a replacement tuner?

Try phoning the sponsor's shop. You can also post in the classifieds just in case someone has one to sell.

There are some postings on the Internet on repairing the tuners if you want to try that. Be aware it might also be Power Supply on receiver. I have a solo se but only the hybrid c/t tuner.

Please make sure you test on a universal LNB, not wideband outputs for Sky Q.

why reparing the tuners of a duo2 ? .They are interchangable .Cost 60 euro max

PS : Could be simply the condensors who are faulty

Hopefully it is just a faulty LNB. Testing at neighbours place is a good test to rule out his dish, lnb, cables.

Test at the neighbours gave 16 dB SNR and signal lock; whereas I’m seeing zero. LNB/dish it is.

Thanks for the advice!
