Will try it when I reach home tonight...
To realign the LNB I need to get access to it right? What you mean is to physically align it right?
I need to get to the satellite dish itself to align right?[attachmentid=7466881][attachmentid=7466881]
Sorry for late reply.
Based on the transponder scan results, unfortunately yes, satellite dish realignment is required.
Whenever you are experiencing technical difficulties and you want Astro to send technicians to your premises to assist you on this, you need to know that:
If your Astro subscription is RM100 or below per month, Technical Service Fee of RM53 will be imposed for the Astro technical team to visit your premises each time.
If your Astro subscription is RM100 and above per month, Astro call this as "premium customer", therefore NO Technical Service Fee, meaning that they can settle your technical related problems for you, free of charge.
If your Astro subscription is RM100 and above, why not just tell Astro and let them do it for you? If your Astro bill is RM100 or below, well....... (you know the answer)
Note: I can only give you advice on realigning the satellite dish and the LNB but I will not hold responsible if any undesirable things occur.
Before you begin, tune to any of these channels: HBO 411, Astro Wah Lai Toi 311, Bloomberg 519, ABO Tayangan Hebat 130, CTI Asia 316 (it doesn't matter even if you didn't subscribe the channels)
Once you are already watching on the channels listed above, press home>Settings>STB Diagnostics. Perhaps you shall ask someone to keep an eye on "Strength %" on Tuner 1 (and also Tuner 2 if you are using PVR decoder) by telling you the signal Strength reading(s) while you're adjusting the dish/LNB. Based on your transponder scan results, the Strength % when you're watching on the channels listed above should be around 70%.
Firstly, I advise you to adjust the satellite dish first. Loosen the 2 hexagon nuts for adjusting the dish azimuth (highlighted in blue) until it is good enough to move the dish in left/right position. Do not loosen till the nut come out.
Once you notice that you are able to adjust (move) the dish in left/right position, stop loosening the nut and begin adjust the dish in left/right position, very slowly, bit by bit, while ask the one that is currently keep an eye on the Strength % your TV screen to tell you what is the current Strength % reading. Keep adjusting until the Strength % reading is minimum 80% and above. Try your very best to adjust the highest Strength % as you can. The higher the better. Of course, if you adjust until the signal Strength is 0%, just reverse back to the position you've adjusted earlier to get back the signal.
If you've tried very hard to adjust left/right position of the dish but Strength % isn't go any higher than 80%, then you may need to adjust the dish elevation by loosening the screws highlighted in red based on the picture above. As usual, loosen it until you can align the dish upwards/downwards and not letting the screws to fall out, slowly move upwards/downwards bit by bit until Strength reading is 80% and above.
The Astro satellite dish location you saw above is within Klang Valley area. The elevation reading appear on the picture is around 77 degrees as you can the scale reading on the dish holder. If you stay around Klang Valley area as well, you can take the picture as a reference for you to adjust the elevation accordingly. If you are living in other states, the elevation may be slightly higher or lower than 77 degrees (approx).
If still doesn't go above 80%, realign the LNB. Loosen the screws (highlighted in green) until it is good enough to turn the whole LNB around.
While you turn the whole LNB around, with the "astro" logo on the dish facing towards your face, take the LNB output cable port as a guide for pointing the "clock position" as it should be around 2 o' clock to 4 'o clock position. Tip: Pointing towards exactly 12 o' clock or 6 o' clock will result in complete 0% signal.
-----
If you've got the Strength reading of 80% and above, tighten all the nuts/screws very tightly while still continue to make sure the Strength % readings maintains the same and does not drop as you tighten it. Once it is done, try go to the channels that you are unable to watch previously. If you are able to watch the channels, congratulations.
However, If you get the Strength % reading of 90% and above, bravo! Thumbs up!
To make sure the issue is completely solved, do perform transponder scan again, make sure all the transponder frequencies has the Strength % of 80% and above. If you got a few ones that has the readings of slightly lower such as around 75%, well erm... it should be fine. However there are some selected frequencies where it is supposed to be no signal at all. Don't worry, this is normal.
Tips:
1) Aligning a satellite dish requires a lot of patience and time. Please don't be in a rush to align the dish.
2) Always align the dish slowly because satellite signals are sensitive. You may get strong signals easily but at the same time you can lose the signals easily. So make sure you tighten the nuts and screws very tightly after finish the dish/LNB alignment.
3) Safety comes first. Be careful especially when you're climbing up to the rooftop when aligning the dish.
4) The higher the Strength %, you won't experience rain fade that quick compared if your Strength % is lower. (Just if you don't know, rain fade is a term where you tend to lose satellite signals when it heavy rains)
5) If you adjust the dish/LNB until the signal Strength is 0%, just reverse back to the position you've adjusted earlier to get back the signal.
Hope my guide can help you to solve your signal issue.
