Hi guy's sorry to reserect this old message I changed my QF3 about 2 month ago and ever since I can't comunicate with my HDD it has power as I can here it spining and I have 5v anyideas as to what else could need changing. the hdd works in a external usb any ideas what else I could have blown when I reversed my dom. :(. As I say I've got everything working but not the HDD.
Thanks
Maybe you can check the power on each connector when the HDD is in a working place. Then check every connector in the AZBox.
I could not help more but as a information - my tuner only work without diseq for about a month. It looks that there is a slow death as a reaction of my wrong connection. I also have no idea where the problem could be.
anyone who bought too many of the parts of them got any left over ,,, rs comp out of stock

Does anyone have an idea where the power for diseq on tuner is set or should be. I can't tune to channels on the AB on my multiswitch - and I have a new tuner but it doesn't work anymore. So the problem must be a power problem on this part like I had with hdd et.al. AA is working normal.

AZBox tuner module have only one LNBA IN & other Line OUT "Master" for Loop Through, that it's routed on LNBA input (controlled with MI input pin with D3 diode inversion protection) on standby mode ...
and has an internal oscillator for generate a tone bursts (22 kHz square wave) and modulation that can be controlled from ENT pin input (start/stop oscillator) ... and from EXTM pin input (External analogic modulation) ... for designers who want to implement the DiSEqC protocols.
This is a photo of the DVB-S2 tuner module:

This is datasheet of ST-IC LNBP20A: Attachment 51441
So you have to check ... if the EXTM pin input is used ... or ... if the module DNBU24512ICC is capable of generate directly DiSEqC signal on LNB output (controlled by CPU with his I2C data-bus) ... for find the problem !
I do not see other possibilities !

Hi arcibald
Thank you very much. I have to check this. I'm using this kind of monoblockl. At the moment I'm on holliday but I'll check it in a week.
One question occured to me, where is the power entry for the tuner modul and how high is it. Are there more than one entry to the tuner?
Because I bought a new second tuner and it has the same effect with not being able to tune diseqc AB there must be a problem on the main board.
Strange things happened - I upgraded to SPaze 2.1 and now the tuner is working normal. There was a problem with naming in astra but I can't tell if this was my problem.
