Image get pixels that can no see anymore

I buy this VAVA projector 1 year and 4 moths years before and now I have this problem (check the picture) anyone can help me?



I have the same problem but not as bad. Their going to tell you , you only had a one year warranty. Person i spoke to told me this is a reoccurring problem then told me to go through Amazon to get it replaced. Yeah right,Amazon said to go through the manufacturer told me take them to small claims court . Still using it but i know its going to get like yours just a matter of time . CACA
