KAKKI GREEN problem solved. I think

by stewart norrie Feb 16, 2006 7:11AM PST

After a week with my new d.l.p. 72" Toshiba I have seen little flaws like green skin tones in dark areas, picture to dark on c.s.i. shows.etc etc. Well last night I watched a IMAX movie on Discovery mindblowing I then switched to the Descovery h.d. channel and the picture was just as good So is this picture problem caused by the broadcasters and why? In closing I have asked you folks before about the kakki green skin tones well today I went to Circut City and watched 9 hi-def sets side by side and they all had this greenish effect So before I go to have a eye implant please let me know if you see this green monster hardy ha ha stewart

Before you drive yourself nuts...

Stew,

Spend $20 for either the AVIA or Video Essentials DVD Setup disc so you can go through your setups, step by step, and properly adjust your hues, colors, black levels, grey levels, white levels, brightness, contrast, etc, etc. If any of these are not properly adjusted, your TV may display problems. I don't know about your Toshiba, but my Sony LCD has a 2-position setting for black levels (enhanced or normal), and I notice when I have it on "enhanced" my blacks seem to be nice and dark but they sometimes look like ink blots. Have you been through all of your TVs setups rather than simply plugging it in with default setups? You may find that when you properly adjust the levels of color, hue, black levels, etc, that your TV may initially look darker (but better), but it won't bloom colors or get rainbow artifacts.

Once you have setup your TV, then worry about what the broadcaster is doing. The broadcast stations distribute horrible signals. Even the "HD" channels often take crummy standard-def material and up-rez them for display on their HD channels. If it wasn't originally shot in HD, then it isn't HD. Plus broadcast material is made up of a mish-mash of material of different resolutions that often are unwatchable on a HD set. If you want to see nice HD material, tune into the Discovery HD Theater every morning from 7am to 8am and watch "Sunrise Earth" . This is shot in HD and broadcast in HD. Stunning!

DAN I DID ALL THE CALIBRATIONS
by stewart norrie Feb 16, 2006 7:48AM PST

I made all the user adjustement using a essentialls d.v.d. So after a week I still see this kakki green effect especailly on the network hi-def over the air stations and t.n.t. The only stations that look beautiful are h.d.net, h.d net movies and the discovery channel and every d.l.p. set I see on display in stores look greenish. My last hope is a eye transplant or the new Dish 211 box with empg4 technology PLEASE DONT TELL ME I'AM GOING ,MAD ha ha

Call the store?

Stew,

Have you tried calling Magnolia or visiting them and describing the problem to see what they think? After plunking down several grand, would they do a warranty in-house service call?

I'm headed into a biz meeting. I'll read later.

Some add'l thoughts

Stew,

Last night, while walking the dog in our "terrible" So. Cal 60 degree Winter weather I was thinking about your TV and came up with some additional thoughts. First, if your TV is showing the color artifacts only in some channels, the problem most likely lies with either the TV station or the lousy compression that the satellite company is using or the actual cable box. I read that both cable boxes and satellite boxes can be set to a "pass-through" mode where it allows your TV to convert the video signal to 1080i. Your TV definitely has a better signal converter than your satellite box. This might be an option. Or, how did the satellite company setup your box to send the video signal? My cable box was set to convert everything to 1080i. This makes HD channels look stunning but SD signals look like crap. But it also had an option of 720p. Not sure what might look better, but if your box isn't set to the best output mode, it may be causing problems. Also, does your Toshiba have a setting that allows it to convert the video signal to 1080i or 1080p? Maybe it's conflicting with the scaling that has already been done by your satellite box. If in fact the problem is caused by the compression used by your satellite company, you might be stuck.

Also, you have your satellite box connected via HDMI, so connect your DVD player into the same input. If your DVDs look fine using the same input connection, then start pointing your finger at the satellite company. You might also want to try connecting your satellite box using component rather than HDMI. If you still have the problem, then start pointing your finger at the satellite company.

Anyways, just some ideas.

The more I have checked this out, it looks a bandwidth problem, since I have dish also,, they are hurting for bandwidth,,many chanels have a lot of compression. This usualy shows up in the shadow ares, detail is very bad as is color balance.
IT IS NOT your TV. John
