I purchased a tv and I had problem with it switching off on it's own.. it makes a screeching noise and switches off and back on while watching.. this issue was within 30days... we took the tv back to makro nd they sent it to supplier to asses, supplier comes back with no issue report and that we should pick the tv up from makro.. I refuse to take this faulty tv as they are not sitting and watching the tv to pick up this fault .. what can I do as makro says they can only exchange and give us new tv if the supplier approves while supplier mentioned that makro will decide what they want to do..
