No guarantees... you can try this to see if it can help solve your problem....

1) Switch off power to the old Astro decoder box, not standby.

2) Remove the smartcard. Use a clean cotton cloth and slightly wet it with clean water. Then clean the smartcard SIM area as shown in circle from picture below (click spoilers)...

3) Also, inserting the smartcard in the wrong direction can cause problem so make sure its correctly inserted. IF the SIM area is bottom when you remove it, then re-insert back the smartcard in the same direction with SIM area at bottom.

I have 3 decoders, 2 old Astro box and 1 Byond box. My Dad sometimes have the same "service is currently not available" problem so I removed the smartcard, cleaned it with special "Contact 90" chemical (Made In Germany) which dissolves oil and dirt and also dries quickly without corroding the surface. After cleaning it, no more problem. I did it twice in about 2 years ! Warning... never clean with alcohol, kerosene or any normal cleaning chemical that can dissolve or "attack" the plastic smartcard !!!

If you have already tried cleaning the smartcard before and found that it did NOT help, then "maybe" your old Astro box got internal problem.

I am not sure if your Astro box is spoilt or not BUT if you are willing to risk wasting your RM 100, then you can try buying the old Astro box from others... search for Astro dealers or TV/HiFi shops in your area because I believe there are shops that do sell your old Astro box (new unit). You can also find people selling it in Lowyat.net too... example... "http://forum.lowyat.net/index.php?showtopic=2479296&hl=astro+decoder+for+sale... I don't know this person so I am not responsible for any risks.

When you decide to buy, try to find a newer model for the old Astro box as shown in sample picture below (click spoilers)...

Also, please don't blame me if you wasted your money after buying the old Astro box from others and then found that the same problem still exist !! Remember, its your decision because I am just giving my suggestion only.

Note: I believe that you already know that the smartcards can be used on any old Astro box... BUT for the new Byond box smartcard, it is locked and cannot be used on other Byond box or old Astro box (no sharing).
