It's okay now, i assume?

mine is 571,722,725, 830.. what is wrong? should call cs fix this issue?

It appears that you are unable to receive channels from the satellite transponder frequency of 12396MHz. The HD channels you mentioned are all from the same 12396MHz, which includes 709, 571, 722, 725, 637 and 830.

If Astro assign a technician to visit your premise to fix the technical problem after you tell them about this, the service fee will be RM65. Of course, you can adjust the satellite dish by yourself, provided if you are know how and confident enough.

To double confirm whether is it your satellite dish problem, you can check signal % reading by doing these steps (If you explain to Astro about the issue you encounter, they will advise you the same thing as below):
On your Astro remote control, press "home", and then "Settings" > "STB Diagnostics"
Press right arrow button to select "Tuner" tab, and then press the green button on your Astro remote to start Transponder Scan. Select "Yes, continue" to start the scan. Once it starts, it will show this:

You should get all 29 frequencies that stated as "Locked", and with the "Strength" reading of at least 70% and above, or recommended 80% and above (just like the screenshot above), except:

17. 10812MHz
19. 19111MHz
21. 19113MHz
28. 19120MHz

where these 4 transponders/frequencies at this numbering sequence aren't supposed to have signal (as of 15 April 2018), so it is normal that it is shown Unlocked and the Strength reading is 0%.
Other than these 4, you should able to get ALL frequencies. If any one of the frequency reading you get less than 70% or shown as "Unlocked", then satellite dish realignment is required, or check your cable condition. In your case, if 12396MHz is shown as Unlocked, and Strength reading is 0%, then..... you know the problem.

You know how to align the dish? Do note that I will not hold responsible if any undesirable cases occur (e.g. you adjust till the point you lose signal, or signal becomes worse than it is, etc.)
But actually, Astro's satellite signal is very strong and it is considered very easy to adjust, so it shouldn't be a big issue.

But then, do check the condition of the cable and the connector port. If it seems okay, then proceed to align the dish.

1) I recommend you tune any of these channels before begin aligning your dish, which are 411, 391, 702, 701, 327, 413. It doesn't matter whether you subscribed to it or not.
2) Once you tuned to any of those channels, go home>Settings>STB Diagnostics, and then go "Tuner" tab.

3) Ask someone to monitor the Strength % reading on Tuner 1 for you while aligning the dish. (unless you can see the Strength reading on your TV screen while adjusting your dish by your ownself)

Before you begin, perhaps you can start it easy by turning the LNB skew. If turning the LNB skew doesn't increases the Strength % reading, then only you align the dish. Just loosen the nut a little bit, enough for the dish can be moved will do. Don't need to loosen it until entire nut comes out (unless you want to dismantle your dish, lol). And then, align the dish by moving it left/right/top/bottom position slowly, move bit by bit. Satellite signal are sensitive, as either you get signal easily, or lose signal easily. So don't need to move too much at once, but in case you really lose the signal entirely (Strength 0%) while aligning, you can adjust it back one, don't worry.

Do try your best to make Strength reading goes as high as possible while aligning. Let say you adjust until 80%, do continue align, and then it shows 85%, continue align again, suddenly it drops to 70%, so you align back to the position you get 85% earlier. (Just like doing manual focus on your DSLR camera). Once you get highest reading possible, make sure the Strength reading maintains and does not drop while you are screwing all the nuts tightly. Done, and congrats, you are now an Astro installer/technician. Haha 

Remember, safety first (if your dish is installed at your home's rooftop).

Congrats... So what's the Strength reading you got now?
And, do you find it easy to adjust?

Haha mine 99%😄
