Hi there....I have a VU+ Duo and it has run fine for a couple of years....it was all setup by my supplier.

Recently it has been dropping some of the channels and so I tried to fiddle with some of the tuner settings and am now getting nothing :(

Here are the settings I am using....hopefully I am doing something wrong in here that someone can help me with?

Hmm, wondering if my tuner might be faulty?

Your LNB is almost certainly the problem.  Originally my dish had exactly the same Sharp Dual-Throat LNB as you have there, originally installed by Sky.  Some channels started dropping out during sunny days only to return at night.  Eventually, it got much worse and I had almost no reception during the day.  As you have found, MySky continues to work, but it seems they have a wider tuning range than Vu+ Duo, hence can cope with more LO drift.  A Sky Tech. I know told me that thousands of those particular LNBs have had to be replaced all around the country.

Replacing the Sharp LNB fixed it for me, and that was 3 years ago now.

Hey grant, thanks for the input. Anyone know of any technicians who could come test and if required replace?

I'm not a satellite tech. but managed to do the replacement myself.  If you look at the Signal Meter and Quality % displays given by your Vu+ Duo, you will be able to rotate the new LNB for the best Skew.  So long as you don't alter the dish pan or tilt, you should be fine.  A new LNB only costs about $40, which will be cheaper than calling out a tech.

Ok might give it a shot. Any recommendations on LNB to replace with? What worked for you?

I would suggest one of these because it has a 10.75GHz LO, the same as the Sharp, and it has excellent performance:

When I replaced my LNB, they only had the 11.3GHz version, so that is what I used.  It means you need to change the setting in your Vu+ Duo, whereas if you use the one above, no changes are needed.

Depending on your dish, you may need a mounting bracket as well:
