Picture blurred. when i turn on the camcorder the picture is brown fuzzy but yet has a brighter

Question

when i turn on the camcorder the picture is brown fuzzy but yet has a brighter spot where light is( for example if there is a light bulb in the upper right corner)then it has a brighter spot but you cannot recognizeany shapes or details. Samsung has repaired 10 months ago and it is happening all over again. They never told me what was wrong.
