As what I observe according to your transponder scan results, you are receiving below average satellite signal strength from Measat 3a satellite (number 13 until 18, frequency 12xxx MHz) as well as other satellites. By right, you should receive all transponder frequencies with the signal strength of above 80%. Anything below than that, either you will easily lose signal when it rains compared if your signal is 80% and above, or pixelation or sudden black screen will occur.
In this case, satellite dish alignment will be the solution, if you can reach to your satellite dish easily (DO IT AT YOUR OWN RISK). Otherwise, tell Astro to arrange a technician to your premise to solve the issue for you. The Technical Service Fees will be as below:
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.
You may increase your subscription to RM100 and above then the next day you call for technical service.
After they came to solve your issues, you may want to downgrade to below RM100 subscription. The downgrading fee with GST still less than RM53.
