Bring your decoder to your neighbour and check if it works? Otherwise get/borrow another decoder replace with yours try and see if you still have the same problem.

This is just to check if your decoder function properly not or the cable link to your unit is giving you problem.

No need to get angry la. The RM50 is for the service technician to come over to trouble shoot the problem. The fee is the techinician's salary.

If you really wanna save that RM50, then you have to do the trouble shooting yourself. That's to check the decoder and cable which already mentioned earlier. If the decoder and cable is working normal, then quite likely it is the connection point to your unit, if so you can save RM50 and complaint to the management to solve the problem for you.

Cheapest way is to cancel your astro and subscribe a new acc.
