i'm new to the forum and have joined because of a similar problem that we face here.
THe 45" model with separate box and bottom speaker is called LC45G1M in singapore and malaysia.
i bought mine about 2 weeks ago.
singapore does not have HDTV on cable. the signals are analogue.
my 45" displayed very prominent clayfacing on both regular cable as well as on DVD. Watching the british open golf last week gave everyone a headache as the greens and the fairways appeared as a green blotch. faces looked like one they were done by those makeup artists at the funeral parlour. there was no detail in the images. worse than my bro-in-laws low-end plasma tv.
I called my supplier who promptly sent 2 technicians by with hi end component cables. the component cables did alot to increasing the 3d depth and clarity, but did not resolve the clayface issue.
2 days later, the director of my supply shop, his 2 technicians and 3 other senior engineers from sharp singapore came by the place.
they brought a HD DVD player imported from Japan, the expensive interconnects, another 45" panel with box and HD DVDs.
THe extensive tests showed little difference in changing AVC, changing to the new panel, watching thru HD DVD player with HD disc with both panels and boxes in various combinations.
They acknowledged that the clayfacing was not acceptable, but one sharp engineer did say that the images tend to improve as the panel "burned in". ( i didn't buy that as he could not guarantee how long burn-in time is needed, and what if after 'burn-in' it still shows the problem. i also asked why if that was the case, sharp didn't burn-in for us, or tell us earlier in the purchase to manage our expectations as it was their flagship TV and cost us about US$8 grand here.)
My supplier decided to take back the TV to his shop at his own expense, and sharp did not even offer to take the set back from him. the whole entourage of 6 men left my house with 2 huge panel boxes and 2 medium AVC boxes. I'm back to my 29" CRT and my son is happier now that he can see the detail of ernie and berts face and the corrugations on cookie monster's cookies.
now i'm stuck with a reflective mini crt screen. My supplier says he hopes i will do business with him again....of course. He honours his word, unlike many nowzadays! his suggestion was to look at the 40+" pioneer plasma with non reflective screen- any suggestions?
