View Full Version : HELP! Hitachi Ultravision 65xwx20b is showing only 90% of my picture!

Hey all, just moved and finally got my Hitachi Ultravision 65xwx20b out of storage and set up. But it's cutting off a good amount of the picture on my hdmi/dvi fed video signals (my cable box and PS3 are fed this way).

Things I've tried/noticed-

I've run MagicFocus a couple times already, and it hasn't helped.

It doesn't seem to lose any picture, or it's not nearly as bad, when the picture is fed via component input.

The picture loss is not as bad vertically as it is horizontally.

When I display a 4:3 picture from my cable box, the picture measures 36 X 32, or 9:8, so everyone looks like they've just gone a weight loss regimen.


I don't see anywhere in the menu to adjust picture size, can anyone help or point me to some help? thanks in advance!

Suggestions anyone?

I should mention I'm running the signals through a Yamaha 661, then using a HDMI to DVI converter attached to the end of a 6ft hdmi cable. Don't know if any of that makes a difference....

I caught your post over at the Front PJ forum an I have an Ultravision although mine doesn't have the DVI input as it is older HD model. However it sounds like the TV is not shifiting the image to center. This could be that it is not recognizing the scan rate. Even though the image is shifted, is it still converged or is the convergence off as well through the HDMI?

As I understand it is not doing it through the component....correct? Are you sending it an HD signal at 1080i through component? Is that working fine?

Right, through the component input the tv is getting a 1080i picture and is displaying it just fine.

Convergance looks good, picture looks good. It just looks a little magnified

If it's an overscan issue, there are no menu parameters (user or service) on most Hitachis to bring it in, AFAIK.

Overscan reduction requires the physical altering of the H and V size pots inside the set (on a Hitachi, they'll likely look like white plastic "Philips head" pots, one for H one for V. These adjust the size of the image being projected.

However, oscan reduction with this method will almost assuredly put your convergence and geometry out of whack, esp around the edges. Conv/geo errors are totally fixable in DCAM mode, but can be seriously time consuming (and headache inducing), not to mention damn near impossible for someone with no exp in image structure tweaks.

Might be a case for a pro calibration.

Alright, I need a little more help on this one.

I just had the Sears techs out to try to correct the issue, and they were pretty clueless as to how to get that done. One (there were two of them) told me that it looked fine. I showed them how you could see the problem easily by using the PS3's image viewer, and also showed how station logos were being cut off.

They left without replacing or correcting anything, just moving my horizontal and vertical positions a bit to center the picture.

Anyone have any ideas for the next time I have them out, to demonstrate that it's not my devices feeding the images, or my hdmi being fed through a dvi adapter, or anything else, that it's actually my tv?

The only thing I could think of is to buy another HDTV, stick it on top of my TV, and switch the HDMI cable from one TV to the other. That seems a little dramatic to me, anyone have any other suggestions?

If coomponent HD signals fed directly to the TV sit normally on screen, perhaps it is due to the HDMI/DVI source. But couldn' t say for sure.

Of course, those Sears techs aren't always on the ball.

It the set worth enough to you to get it pro calibrated? Overscan reduction performed during a cal should fix it (and make it look even better overall)

Agree. There are no Hor/Vert size adjusts, except pots which control ALL modes; so, it's not those.
Since OK on component, then possibly receiver has a setting for TV type? I think receivers decode the HDMI in ,and then recode it for output. It's not just a switch selector in there.
Check set-up of receiver.

One of the things the Sears guys and I were able to figure out is that it DOES have the same problem with component. I don't know how much that changes the equation.

They spent some time playing with the screen with the internal adjustor that spreads the screen out or brings it in, that did nothing as the TV seems to be showing all that it thinks it should be showing.

We also cut the receiver out of the equation, and ran the component and hdmi cables directly to the TV. That didn't change anything.

I'm just wondering how I can PROVE there's something wrong that needs to be fixed. I have until mid-September to get this right, after that time I have no warranty on the TV. If I can't prove that's it the feed coming into the TV, they'll just keep pushing off to that excuse if/when I press them to repair the set.

Hook-up cable box with component cables directly to TV.
Set TV to that input with cable box on. Got pix? OK

To set cable box up: Turn off cable box and press 'select' button on box. See white screen with set-up options? OK.

Using that 4-way cursor/buttons to right (rt./lft./up/dwn.) make sure ,and set, to :
TV screen = 16:9
YPbPr = 1080i
480i override = 480i

Hit cable box power button = OFF
Hit power button again = ON

Pix OK?

No? Hit aspect button on TV remote.

If TV aspect says 'wide', 'smooth wide', or 'full', and pix still narrow, you have prob with TV.

I have one of these. With the digital signal from my cable company the picture does get cut off & never paid attention to it because I wach only a little of it. I, however have encountered another problem.
The picture pixelates & then screen goes blank for a few seconds then comes back & this has been a recurrent problem for last several months. Sears technicians have replaced the HD tuner without any success. They keep telling me this is a signal issue. The cable company measured signal strength & it's okay according to them. Another TV I hooked up in the sameplace does not have this issue. Any help will be appreciated.

How is the cable box connected? DVI/HDMI or component. If the former, your Hitachi could have a similar HDMI/DVI "handshake" issue that some newer models have had.

The F59 series CRT RPTVs from Hitachi had some crazy issues with their HDMI inouts that was (mostly) resolved thru a software modification in the service menu. I suggest calling Hitachi Customer Relations @ 1-800-654-7013. Let them know which model you have and what equipment you are using with it that causes this problem.
