No Sat Signal

[any-mgzt]

I have no satellite signal, neither tuners will lock on at all. started with tuner 2 not getting Horizontal signals, its not the LNB as my Sly receiver works fine and shows good signal on both tuners.

I have measured the open circuit voltage on both tuners Tuner 1 Vert 13.5V Hor 18.5V, Tuner 2 Vert 0.0V Hor 18.5, so tuner 2 is clearly not working for Vertical polarization transponders.

But I cannot get a signal with tuner 1 either.

All I have done is change the fan, as the existing fan would not allways start and the unit was getting quite hot, to change the fan you have to remove the PSU and hard drive, all went well and everything connected correctly.

Worked fine for a couple of hours and then nothing at all??

recheck your sat setting on box did you,strangely enough i lost signal on one tuner and checked feeds on other box worked and tuner b does not.

If you just have 28.2 dish then mode should be set to single.

i see he has diseqc,are they setup ok /recheck settings.

I am no exspert but if all was fine before you fitted the fan i would back track my assumption is the box was ok after for a while therefore as it has heated up something is not seated correctly.
i would re seat your psu and check connections as with exspansion many things can happen.
if still not working remove tuner 2 and see if it makes a differance.

dont think you can remove tuners on these boxes so dont try,duo2 yes as it has swappable tuners.

Tuners on the Duo are soldered to the mainboard exactly like the Solo2, from the pictures i cant understand also why you have Diseqc A/B selected on both tuners with the exact same satellites.

Your setting should be Simple - Single Satellite - Astra 28.2? east on both tuners if that is you only have a fixed dish
