Hello all, first time poster. I have a sanyo ht30746 30". The screen seems cropped in any picture mode without vertical black bars. For example, I was watching House, and the FOX logo in the bottom right corner was missing the X. This happens even when watching HDTV channels. Is there any way to fix this via the service menu or something like that? Has anyone had similar problems with their TV? .
Screen seems too big?

Hey mastag, welcome.
You may have the TV in a "zoom" mode. Check your picture mode or size options and try to find the "normal" widescreen mode. Where are you getting your TV service from? Cable, Sat, or over the air?

The only options for my TV are: pix1, pix2, pix3, and pix4. pix1 has black bars, pix2 is normal i think, because HD channels don't look distorted at all. pix3 and pix4 are just more zoomed in. I have directv, and an HD receiver running in 1080i.
I believe you will want to use either pix1 or pix2 modes, and probably never use pix3 and pix4. Pix1 would be the normal way to watch it, with HD signals filling the screen left to right, and SD signals will have the black bars on both sides. Check in the setup menu of your Sat receiver that it is set for a 16:9 or widescreen TV and that the resolution is set to 1080i. Are you using an HDMI or component connection?
actually, pix1 even shows High definition with black bars on each side. Pix2 has everything from left to right, and HD looks pretty good, except for the aforementioned problem. I usually watch in pix2. I am using component cables, the resolution is 1080i, and it is set for 16:9. I might just have to deal with it. Returning the TV is not really an option TBH.
So, if you watch ch.76 DiscoveryHD, except for some commercials, the picture does not fill out the whole screen in pix1?

Correct, except nothing fills the screen in pix1. However, if I use the Directv remote to zoom, the HD channels stay the same no matter what.

Well, don't give up. There's a reason here somewhere. Which DirecTV receiver do you have and did you install a new oval sat dish?
We installed a new Dish, our old one didn't receive HD signal. We also got an HD receiver, i'm not sure which exact model. The weird thing is, when watching standard definition anamorphic widescreen DVD's, the problem does not occur at all, which makes me think it is the satellite, rather than the TV. I'm not sure though. I contacted Sanyo, and they gave me the "when in doubt, return it" answer.
According to your owner's manual you should be using pix2 for 16:9 hd sources.
Make sure you tell the DirecTV receiver that the TV only supports 1080i - otherwise you might not be getting a 1080i signal all the time.
Then check the formats on the DirecTV receiver - make sure it's not set to crop or stretch.
Then go to a channel like Discovery HD or HDNet that is 1080i all the time and you should see a normal HD picture without pillar boxes or stretching. If you don't and your TV is on pix2 then I think it's the sat receiver settings.

I have all that set up. It is more noticeable with 720p channels and SD channels. it is still there with 1080i broadcasts, but doesn't seem as noticeable. Planet Earth looked fantastic in HD, as does shows like Battlestar Galactica, Firefly, etc. I think it is the receiver, but I haven't found any settings in the menu that can fix it. It is not a HUGE deal, just more of a smudge on an otherwise great experience with HD, since this is my first HDTV.
Now I feel so stupid. And I bet Richard does too if he's reading this topic.
The answer is so simple. You have a CRT. Your problem is OVERSCAN.
Your TV is cutting off up to 10% of the picture edges. It may or may not be fixable through the service menu.
My Mitsubishi CRT RPTV has a bit of overscan on 1080i from my HR20 (it cuts off the very bottom of the on screen guide). And Richard will remind me that he can easily fix that for me, but it doesn't bother me that badly - yet.

Well, at least I know what the problem is now. Too bad the service menu is a bunch of numbers that mean nothing to a n00b such as myself. Like I said, it is not a deal breaker, just a minor imperfection.
edit: do you think it would make any difference if I used HDMI instead of Component cables? I plan to get the elite version of the xbox 360 next month, and I plan to use the HDMI outputs.

I did a google search on your tv model and there were lots of overscan complaints.
I think it is possible that a different source and/or connection type could have more or less overscan. Some devices also let you adjust the picture output to fit the display.

Sorry to tell you mastag but what you purchased is an entry level display. It will give you a good taste of HD but accuracy will require far more money. Based on what Akirby found it seems to be a common problem and while a calibration could reduce it it is the nature of your beast to have a healthy overscan.
The only displays with 0 overscan by nature is front projection and flat panels and even then you would want to see a review to make sure the internal scaler is not overscanning.
Ultimately, if performance is your bag you need to work with an ISF calibrator or dealer to help you select the right products to meet your level of performance.

If it's my TV, how come it never happens with DVD's or Video Games?
There is what is called a safety zone that content producers for NTSC have always had to adhere to prevent the kind of problem you are having. A safety zone means they know you have healthy overscan and if they put any important content such as game scores to close to the edge some folks at home may not see all of it. For NTSC this has been set at 10%.
Without such graphics on screen you would not notice with DVD and DVD is defintely designed for 10%. Game designers are also well aware of this (they discovered this the hard way over a decade ago) and even with HD games they may still be following the 10% rule to stay out of trouble.
I don't know if there is a standard for HD content but in practice I do see some pushing things a bit closer working more at 5% instead. ESPN is definitely working with a 5% safety zone!
Folks like yourself with such complaints are few and far between and since CRT is going into yesteryear it won't be problem at all for nearly all new buyers within 1-2 years. MD projectors and flat panels are less than 5%.
Performance enthusiasts prefer 0 overscan if at all possible.

That makes sense. However, I checked by playing a game in pix1, which has black bars, and then I put it in pix2. There was absolutely no difference in what fit the screen.
K... but the black bars went away right? All that means is your overscan did not change.
I have never calibrated your display so I don't know the in and outs of your aspect features. You could get a rough idea of what is going on yourself with a calibration DVD and test patterns. If you are using an upconverting DVD player that will nail down what is going on with your aspect feature as it relates to 720P or 1080I content. Set the player for both and compare the difference if there is one.

Those DVD's look interesting, I'll have to try one. What I was trying to say, was that when watching TV with the satellite receiver in pix2, some of the picture gets cut off along with the black bars, but with games and DVD's the picture fits the screen perfectly and only the black bars are cut off.
I think somebody already mentioned...
Gotta check your SAT STB settings and make sure you are not using an aspect from there.
Mixing aspects can create a confusing mess. Both display and STB need to be in 16:9 only for everything to be correct. From there determine which source needs aspect controls for you. With DVD or games this should be rare. With SAT and SD content aspect changes are common in which case I would suggest leaving the TV in 16:9 all the time and do your aspect changes for SAT with the SAT STB and SAT remote.

Well, it turns out that it DOES happen with some DVD's, but it is much less noticeable. I noticed something weird about video games. When in pix1, they seem to have much larger black bars than normal, so that when in pix2, it fits the screen perfectly, so Richard was right, and now I feel stupid. I'll deal with for now, but thanks for the help everybody!
so Richard was right, and now I feel stupid
C'mon... ignorance, what you didn't know that you didn't know, is nothing to be embarrassed about. I have been dealing with that on a regular basis my whole life!
Who doesn't?
Would it make any difference which cables I was using? Like, would it make any difference if I was using HDMI instead of component?
Not for an aspect ratio problem...
I'm a bit late n this game but I too have this problem. I took the covers off yesterday to check internally.
All older TVs had interior controls.. height, width, verticle linearity, vert sync , horizontal sync,, focus..
This TV has focus,, and only one other control, mouted on the crt board..I doubt it will help as two are neaded.
I have about a half inch over scan..
Cure would be to get the schematic and figure out the resistors that control height and width..
Then replace them with a small variable pot and tweak the size....
Suprisingly this set is all discrete components,(mostly) no hundred pin chips.
$16 for the schematic.

Its not really rocket surgery, and the logic boards are wide open and easy to work on..
