Why does the TV picture sometimes freeze or break up into blocks?
There is a number of possible causes for intermittent freezing and so-called “macro-blocking” (pixelisation) of the TV picture. First of all, there may be a fault in the broadcast chain. Such faults are temporary and usually of brief duration, so no corrective action is called for. Secondly, reception of satellite-TV programmes can be affected by adverse weather conditions. The digibox is able to minimise such effects, but will not be successful if the weather is really bad. In this case, the only thing to do is to wait until the weather improves. A larger dish and accurate alignment can minimise such problems. Finally, if the problem occurs in good weather and is common to all channels, it is probable that the cause is poor installation (incorrect dish-alignment, faulty LNB or faulty cabling). Check the whole installation thoroughly. Very occasionally, the fault might lie inside the Digibox itself…..
