Tune fail? 2xDVB-S2 tuners

[paul1098]

I'd previously set my box up without any issues except for the HDD cable detailed elsewhere.

Thought I'd try an external HDD while waiting for cable but seem to have a new issue of Error 'Tune Fail' box coming on the screen.

When the box is hard restarted everything seems ok. TV screen shows bbc1. As soon as I go into epg & then go back I lose the channel & get the error box & 'tune fail.

If I soft restart the box I get bbc1 showing but error 'tune fail' box up as well. picture goes as soon as epg is entered.

Tuner A is the one that fails, I've swoped cables from B & I still have the same issue.

If I disable tuner A then I have no problems with the picture or epg.

Hardware issue or software / ABM issue?


I've seen another thread on this with comments about sat finder & have repeated them below.

Reseat the tuners and at the same time switch them around, then repeat the exercise.
Could be the tuner is not fully seated ... But switching them should rectify that possibility.
Just make sure you touch the metal frame before doing the work ... Just to make sure there is no chance of zapping anything

Changed them around & now it only sees one tuner when booted back up. Looks like it is a duff tuner.

So contact your supplier and get a replacement ... Has happened to me in the past ... My dealer just shipped a new tuner and returned the duff one.

Just done that.
