ViewSonic NextVision N3760W 37" LCD TV

I just brought a brand new ViewSonic LCD TV with built-in HD tunner. It came with problems that the HD tunner has to change channel from high number to low number, or it will not show the TV program. Say you want to watch channel 5, if you were at channel 4, move up to 5, the TV shows no program. But if you move up to channel 7, then move down to 5, TV will show the program. It also often drop out the programs, while our other HDTVs made by Toshiba, Samsung, Screpter all working fine, this TV suddenly stop showing the TV progam and display "no signal".
It is DOA, means it like this when we get it.

I called ViewSonic for replacement. They asked for my credit card number to setup an advance replacement. I gave them my credit card number. But they shipped me a refurbished unit that was returned and repaired in the past.

I paid a new TV price, ViewSonic wants me to accept their refurbished TV. I called their support, and talked to their manager. The manager told me that actually they had changed their policy again, since they shipped the refurbished TV to me. They no longer send out replacement any more. When you have a DOA, they will only repair it now.

I had experience with Viewsonic repair in the past. One LCD monitor we sent last year for repair took over four months came back. Another Viewsonic HD12 HD tuner sent for repair got lost, after six months, they sent me a replacement. I am not sure I will buy another Viewsonic product any more.
