I have a new Toshiba 46" model 46H84 CRT rear projection HD TV. The flesh tones are not very good, even
though the hue control will shift an imiage from purple to green. When i compare this picture to the one i get on my Sony HD, it makes me sick. Does anyone have information
on special service adjustments that can be made to improve it ? Also does anyone know where you can buy a HDMI cable at the lowest rate, Best Buy wants over $100.

As far as the HDMI cable goes, you can go online to www.hdtvsupply.com. They are $25 there.

Is your TV new? In the menu option, does it have auto flesh tone? There can be many circumstances to poor PQ. How is your tv set up?

Are you positive that the component cables from your cable box(assuming you have cable HD) or DVD player are connected properly (red-red, green-green, blue-blue) and tightly? Have you tried the picture with cable connescted straight to the TV, eliminating the box? How is the picture like that?

1. Before passing judgment on the TV, have you at least used the Avia or DVE calibration disks? You can order DVE through amazon.com
2. AntMan has it right - hdtvsupply.com is a great outfit, and I have happily purchased and recommended their products to others. You will be happy ...

This is a new tv there is no auto color contol. The tv is hooked to charter cable and I have an HD programing package. I used to be a tech and know a little more then a newbee the tv is hooked up properly. On my Sony Hd rear projection the picture sparkles on Hi def, on the toshiba it doesn't. It there someplace I can get the service codes for this tv, perhaps there is some automatic hue correction that I can turn off. Thank you for your reply !

How is the picture with the cable connected directly? Same thing?

flesh tones are lousy even on over the air digital, Hd telecast are better but overall lack the sparkle I am used to on my other Hdtv.

Jerry, you have charter cable. what STB are you using?

Antman: I should know but don't, what does STB stand for ?
Set-top-box. In future, check out the FAQ on Acronyms.

Set Top Box. He wants to know what cable box model # you are using.

I have the 51h84. It's a good set. I second the sugestion to calibrate the brightness, contrast, color, etc with AVIA or DVE. I used DVE and am more than happy. Give it a try. My HD signals look just as good as any Sony or other brand I have seen.

Sorry, Jerry...Set top box. If you don't know what kind of box you have, you can look underneath the box. It might help if you can post that because I'm sure other might have that same box, and could share some insight.. The settings could make a difference....post back what you have

I'm brand new to this TV terminology, so please forgive the non-technological terms. I recently purchased the 46H84 model and have digital cable with Charter. Do I have to upgrade to the HD box to get a clear picture? The TV has a weird shadow of the image on the TV. It is most noticable during commercials with lettering against a black background. The best way to describe it is a McDonald's commercial. The golden arches look like there are 3 arches instead of 2. The 3rd one is faint but definately there. The picture looked better on my 19" Magnavox TV bought in 1992.
Shouldn't I be getting a clearer reception? I tried the convergence thing but couldn't figure out what I was supposed to do with that grid. The manual said that lines were not supposed to cross. What does that mean? The TV does this test with the horizontal and vertical lines but I never see them cross. If it means that I shouldn't be getting any horizontal lines, isn't there something that will automatically fix this or do I have to turn into a TV technician to get my TV to work?
I'm thinking about upgrading to a HD box but does that mean that I will only get the clear pictures when I am watching a designated HD channel? Or will all the channels be clearer?
Also, I tried to hook up the digital cable box with the S-Video cable but that didn't seem to make a difference.
Thank you in advance for any help and advice you can give. :cheers:

Welcome to the Forum :wave:
No TV's should give you 2-3 images of a picture on your screen, especially new HDTV's. What most here talk about is just how bad or "grainy" some SD channels are because we are used to the great HD channels, and all the flaws of reguar SD channels are exposed, but that's HDTV life. Now you will need a Charter HD STB (set top box) hooked up with component cables to get HDTV signals from them.
Convergence lines up the rays in your TV, thus increasing the picture quality of what your watching. If your TV has auto convergence, turn it on, and your set should line them up, if you have manual convergence then YOU line the bars up accordingly. For example, (just using colors as example) you have 1 yellow bar, and 1 blue bar...you converge the 2 bars to make 1 green bar, this should be lining up your rays...make sense?
If you get an HD Box, (hooked up through component cables) all your channels should be clear. Your HD channels should look great and SD channels look okay (like I said, some are grainy, but that's just a weak signal), but you should never have 2-3 images of what your watching as you have described having. If you get an HD STB and still have 2-3 images, shadows, I would use a calibration disk, or just return the TV. Some times TV's can just be the problem. I know this was long, but with this being your 1st post, I tried to be detailed.

That wasn't long at all. I appreciate you going into detail for me. I really learned a lot. I guess I'll have to order the upgrade at Charter (I hate the cable companies! They suck you dry!).
I understand the convergence a little more now but I still don't understand that grid after you select the "convergence" then "adjust". The only colors I see are red, green and blue. I don't see a yellow. After the run through of the colors (vertical and horizontal), the grid comes up and it shows different options to "adjust red/blue" or "select position"; "adjust convergence" or "change color"; and "finish adjustment". Whenever I click on adjusting the red or blue, I don't see any changes. What is this grid and what am I supposed to do with it?
Thanks for all your help and I appreciate your detail! :cheers:

It sounds as if you are in the user menu convergence. The red/blue choices are the only ones you actually adjust, to get them to line up to the green (which looks like a white +.). When you choose red, that is the gun that can be adjusted. same for the blue. Converge the red so it lines up directly behind the white + and then do the same for the blue. You will need to do all 9 points (select position) to do it right. The yellow 'grid' for convergence is in the service menu, which, should you venture in there, you should WRITE DOWN EVERY VALUE, (I MEAN EVERY VALUE) BEFORE ANY ADJUSTMENTS ARE MADE.

Just to be clear, there is no yellow grid in the service menu. The grid colors are green/red/blue, which are each generated by the corresponding CRT's.

You should see Red Green and Blue.
There are two different methods available for convergence. One is "user level", the other is "service menu level". The crosses are user level, and they work, but many of us are more comfortable with the service menu convergence. The big difference is that instead of crosses, the service menu convergence gives you a "grid" of lines. This allows you to check your geometry as well, to make sure all the lines are straight and evenly spaced.
To expand on Antman's explanation, your set really has 3 TVs inside it. One is Red, one is Blue, and one is Green. Convergence is the process by which all three images get bounced off a mirror and end up completely on top of each other. So if you were watching a single white box that was 12" square, your set would actually be bouncing the three squares (R,G, and B) off the mirror in the exact same spot, and the result would be seeing a "white" square. If your convergencee was off, you might see a red line "sticking out" from the square on one of the edges.
So the grid/service menu level is only available by entering the service menu. The directions are posted here, somewhere...lol...I forget where. One thing you need to understand is that the service menu allows for MANY more adjustments than just convergence, so you need to write ALL of your current settings down before doing anything else, just on the off chance that you make a mistake and change something you didn't want to change.

I have the 46h84 set and all you need to do is hit the auto button on the front panel and it will ajust your convergence for you!

The problem I am haveing with the set is I have dish network and have not upgraded to hd yet....my picture is very grainy...ESPN being the worst. I have S-video runing from the box to the tv. I am wondering is this a common problem with hd sets when watching non-hd programing. Watching dvd's is great and very clear....I also have my x-box hooked up with a hd pack and it looks great....just confused about regular tv programing. Can anyone give me some advice? Thanks

"I have the 46h84 set and all you need to do is hit the auto button on the front panel and it will ajust your convergence for you!"
Ummmmmmm.....No. :)
That is a "TouchFocus" adjustment, and is the lowest form of convergence/geometry adjustments you can perform on your set. You will find that during the first few hundred hours, the convergence is apt to drift and will require more than just a TF to get the optimum picture quality your set can deliver.
"...my picture is very grainy... I am wondering is this a common problem with hd sets when watching non-hd programing."
To some degree, yes. But with the proper adjustments, SD can be at least "good" on your set...and in some cases, it can be great.
Get a copy of Avia and go through the adjustments on your set...that should help a lot. Get all of your menu adjustments out of Torch mode (everything below 50) and read the "What to do with your new TV" thread.
Lob
Althought the auto convergence is helpful for most people, it's only based on a few "points" - perhaps 4-9. The manual convergence is done on 56-117 points depending on manufacturer. This is much more accurate and gets rid of the colour fringing at the edges and in the corners...

You're doing fine. Everyone was new at it, once ;)
Yes, you can order if from Amazon. There are 2 setup discs that get recommended a lot. Avia and Digital Video Essentials. Avia is more expensive, but I think it's worth it ($38).

playball,
Each of the disks have their upsides depending on what you need to do, and DVE isn't really that expensive, around $20 at most. I got both Avia and DVE, but hey that's just me ... I drank the kool-aid on this whole idea. :guiny:
