I have a SD DVR40 Hughes brand, and about a week ago A service person was out, informed us our brand was going out, and needed upgrading since then I have been sent a replacement , However My unit I have that is going out is a year 2004 the one sent was a 2003 and found out it was defected, then sent another one year 2002, the problem is rainbow effects in the writing and the wording is very blurred. Hard to read. I was reading in some of the posts that this is a common problem. How can I fix it?
Any and all advice I would REALLY like. and Hurry
