I had my replacement tv delivered yesterday. Wow! What an improvement. The picture is much better overall, not perfect, but acceptable.
I had bought a Vizio VX37 a few months back at Costco and the picture was awful. Vizio said it was defective, so I took it back and got another one. The picture was crisper but the colors were completely washed out. This seemed to be the case with all versions of this model I saw. So after reading lots of positive reviews I exhchanged that for a GV42L 42" model.
The colors were nice but the picture on it was out of focus, so I called Vizio and they sent me a replacement board with instruction to contact the service center for install. After leaving several messages with the repair center (outsourced by Vizio) over three weeks and not hearing anything back, I called Vizio and complained. They promised me a new tv would be delivered, but it would take upto 10 biz days. It was delivered yesterday within that time frame.
The picture is better all the way around. It still doesn't compare to some of the other (more expensive) tv's from other brands, but it's not too far off. At $1299 I'm happy. And I can still exchange it at Costco if I decide I want something else.
I noticed that the delivery invoice listed an "A" at the end of the model number and the description said "GV42L HDTV - Grade A." I'm assuming that this means it was gone over at the factory before it shipped and doesn't have the quality control issues I've been running into. Either way I can finally start to enjoy some movies.
