Avoid Magnavox.
Seiki TV's are made by the company Seiki Digital. The company is owned by Tsinghua Tongfang Company, a Chinese company.
Sounds like the LCD display panel has gone bad.
Phillips
There are a wide variety of companies that manufacture 26 inch LCD televisions. Magnavox, Vizio, Sharp, and Samsung, for example, each manufacture this product.
lcd watever
led is better than lcd tv
I just called Seiki about the same issue (I have a 32" LCD). They indicated that the TV was "designed" to default to the 4:3 aspect ratio if you're getting the signal via an indoor antenna or a coax cable plugged into the wall. Very dumb, IMHO!
Most people like LCD better because it has better graphics and sound.
LCD, simply because LEDs suck.
No most people consider lcd tvs better than plasma tvs. Plasma tvs are harder to fix than lcd tvs. Lcd tvs also have a clearer picture than plasma tvs do.
HD is way better.
Although you can connect TV to PC via DVI to HDMI cable, the picture quality is not guaranteed. This is not recommended by manufacturer.
