The Sharp 88UN,
Is an LCD TV,
It's not LED,
Nor is it DLP.
It's a CCFL backlit LCD TV,
The HZ on it are 240,
And if you agree, let's go play Fallout 3.
As for the input switch delay, yes it does take 2-3 seconds sometimes to switch between PS3 and cable TV, or non HD channels to HD channels...but man...are you saying that's a legit "issue"?
That's like saying, "Man, I coulda been 2 minutes earlier to work this morning but I had to put on stupid clothes again today...

"
Hey, I put on my 3D, 20X, UV, FLIR sunglasses earlier today to see if I had any radioactive thermal horizontal/vertical cross banding on my TV and hold crap, I do! There was also dust on my TV and that is not acceptable, which is why i'm returning it asap for a new TV. This time im gonna cover my TV in couch cover plastic before anything can come in contact with it, and have a high priest bless the TV to ward off will-o-wisps, which of course everybody knows are the main cause of clouding and poor black levels...
