Here is detailed information on the issue I'm having with my 30 inch Sanyo Vizon HT30746 HDTV... I sent this email to sanyo tech support as well, to a guy named harry, because Jim was out today.. Hopefull between them and you, someone will simply give me a CONCRETE answer!
Here is what i've come up with so far. Keep
in mind, I have read over 100 posts concerning this TV, but haven't received a
concrete YES/NO answer on it.. Honestly, I don't think it's a defective TV, it's
just the way the TV handles HD singals.XBOX360
-- Hooked up component (tried both inputs to verify, same result).. XBOX
is SET to 1080i (Tried 720P, same result) widescreen mode (Only choice you have
when you set it to 1080i or 720p).. I've verified this several times, and also
checked on forums concerning xbox, it's hooked up correctly. The screen (in
pixshape 1) with the xbox gives me black bars on the left and right, 4:3 aspect
ratio. Yes, the picture is much better than composite (i tested that to see),
but I can't get a full HD 16x9 picture on a 1080i input unless I switch to pix
shape2, which stretches the image, cuts off parts of the image on the left and
right.. Also, looks crappy (cause it's just a zoom)... I am at a loss,
quadruple checked all settings, over and over, same result. Everyone on xbox forums can't understand
why it wont work. Also, I tested this xbox on my parents HD dlp tv, and worked
perfect and automatically was full and not cropped 16xx9.TIVO-HD DVR
-- When watching HD channels such as HBO HD, ESPN HD, etc.. The same
thing as on the xbox.. No 16x9 without the zoom/pix shape 2... Once again, nice
picture, but 4:3 on the tv... I tried every setting on this box, over and over
and over and over, same result. On my parents tv, once again, this tivo hd
worked perfect in 16x9....
Lastly, I see on pix shape 1, on sattelite and some games, an overscan line to
the left edge of where the pic cuts off, about a 1/2 inch from it.. A solid
line, sometimes green, mostly dark gray. Shows up mainly on bright screens, and
I've turned the brightness way down, it helps. I know there are options in
service menu, but I have no idea how to access it, and I don't want to make
things worse. Also, no wal marts in my area have this TV anymore, so exchanging it would be hard.
I hope all this helps. The one thing I haven't tested is THE HDMI input. I
don't know if that would change anything concerning the hd feed, as the xbox
doesnt have hdmi, and I wont be setting up the HD TIVO for about another 3 weeks
(My parents are finishing watching al the taped shows, they upgraded to
directv's own hd dvr)....
That should help.. Keep mind I've checked everything on my own that I could,
read hundreds of post on avs forum and such, and I'm stumped at this point!
