It is unfortunate but "off angle" viewing will compromise the picture especially on larger TV's and LCD. Off angle viewing can come from the vertical axis or the horizontal, as you described. This is clearly illustrated with a laptop computer. Adjust the screen forward and back (vertical plane) and you will see very clearly that you get the brightest picture in a very small amount of range of the screen. Likewise, viewing from the side compromises picture as well.
I also don't believe that the delay is indicative of any problems.

Hello, I just posted this to another user's question, and you might find it useful, too.
I have a pile of these in my shop. Unfortunately and usually, a backlight lamp is bad, and the inverter board is damaged when it goes out. The backlight lamps are sealed inside the panel, so the usual method of repair is to replace the panel.
If you turn the lights off in the room, then turn the tv on, you will probably see a momentary flash of light from the backlight trying to start up. The lamps can be replaced, but the option is not really cost effective given the amount of time it takes to replace them/very delicate nature of the lamps/availability of the lamps/cost of the lamps. Replacement panels might be available, but you'd have to use a TV shop for reference or call Sanyo directly.
These units also have a history of power supply heat damage, so if you don't see the momentary flash, it could be the power supply. But the momentary flash is the dead giveaway.
I hope this helps you...

I have researched this problem and it is so common we that own this piece of junk ought to form a class action suit and sue. It is caused by a bad part or bad connections to a part called a backlight inverter. It seems the LCD needs a higher voltage than supplied by the 12vdc power pack so this part re-chops the DC voltage to generate the LCD requirement.
The date of manufacture is on the back of these TVs and all the problems seem to be from those made in 2006 to 2008
