Please answer question in post 19. This was asked after you had said: "then do a blind scan and can then access all the channels"

What happens when you tune to the ETBG channel?

My diagnosis is that you are not receiving the 11778 transponder.
Not sure how you are "blind scanning", but your tests prove the failure to tune. If the receiver works fine at your place, and not at your friends, then the tuner/receiver is fine.
Think of it this way:
Network scan
Q. What do you have in your suitcase?
A. Here is a list of what I should have.
Normal scan
Q. What do you have in your suitcase?
A. Lets open it and check. I have x,y,z
Sometimes people do not pack what they have on their list. Your mate is only getting 548 out of 900+ channels.
LNB is probably not switching between high/low. It may need to be replaced.

Hi Abu,
Thanks for the explanation and diagnosis.
The blind scan is being rub from the menu in service searching with default prompts.
I'm still puzzled as to when he does a blind scan then all channels appear in the list and are watchable. If there is a fault with lnb then I wouldn't be able to pick up the channels ?
I do believe it's not the receiver. It may well be the lnb but I wonder if its a cable problem too?
Anyway my next plan is to suggest he replaces the lnb. Thanks again.

You are assuming they are watchable. He has probably got the network scan option enabled when scanning.
Get him to try all 900+ channels to be certain.
When he does a blind scan it goes through 4 phases of determining horizontal and vertical transponders and then it starts the actual scan where you see the channels being scanned.
Following this he is able to see all 900+ channels.
I will try and get you screen shots later.
As mentioned I only get tuner lock after running ABM....
Strange.

Seeing a channel in your list is not the same as being able to view it. Try taking out your signal wire, you can still see the channel, but not view it.
ABM does not complete if it gets a tune failed. If you enable 15 providers and get a tune issue on last one, nothing is done.All the 14 successful providers are not written.
You are not getting tune issue AFTER running ABM, you get it WHILE running ABM.
Until you sort signal issue out, you can run LraiZer's plugin. It will work while on any 28.2 service. It only tunes to 11778 service if you are not on a 28.2 service.

Sorry i'm not getting this at all. I run a blind scan as shown In Screenshots and the channels clear.
But when ABM run i get tuner lock. I suppose a lnb replacement may sort it but can't see any correlation between ABM failure and lnb.
As a result I don't know where the root cause of the problem is.

There are option on your scan setup which are not shown. If any of those say anything about network scan, this is the "Here is a list of what I should have."
Let us leave ABM to one side. Why does a normal scan (not blindscan) of 11778 frequency fail?

It is the frequency that Sky receivers use. You can double check the engineer's menu if you do not believe me.
There are no "proper" viewable channels, this is why it is not listed in the xml file and not listed as a predefined transponder. ETBG should be there if you scanned and was found succesfully. You already tried to scan it before.
Anyway, we are going round and round in circles. You insist it is finding all channels AND they are VIEWABLE. (Viewable = you can select them and watch the channel without getting a tune failed message).
You insist that AFTER ABM has run, the channels are no longer selectable. I have tried to explain you are getting this WHILE ABM tries to run. As it cannot lock onto the frequency it needs, it fails and does nothing, so can't be the culprit. "While" is not the same as "after". I have tried to explain receiver works at your place, so it cannot be a receiver issue.
I don't think I can help any further.

If blindscan works and abm doesn't it means the lnb is knackered. Local oscillator is off frequency. ABM looks for channels where they are supposed to be. Blindscan looks everywhere so finds them even when they are in the wrong place.
Do a blind scan and post the lamedb file.

Ok, cheers guys for feedback.
Seriously i don't know whats going on.
Abu, I'm not saying I don't believe as i don't understand what's going on. Clearly it must be the lnb as that is the common denominator in all this process of elimination.

can you manually scan the ABM frequency and show us the screen shot?
if your dish is slightly of alighnment it maybe possible to scan in hundreds of channels but not possible to read all the information from 11778 successfully, just one error in the data will fail the process, i've seen it before.

hello All,
Just to put some closure on this.
Frequency scan of 11778 on the OSMINI produced 0 channels. Swapped out lnb and rescanned - all ok!
Also reran ABM and no tuner lock.
Thanks for everyone's feedback on this post especially Abu who continually preserved with the diagnosis with utmost patience.
