Zenith C27v36(c32v37) Hdtv Service Menu! No Special Remote Needed!!

[STEELERSRULE]

I came across a way on another forum on how to access this service menu using the tv and the rmote for the TV.

Now I am GUESSING this is the service menu, but I am not sure as I delved no deeper than the front menu and went no further for risk of damaging or destroying my tv. I am hoping someone who has more knowledge(a calibrating background would be nice) and the same tv(Zenith C27V36 HDTV Monitor) would be more daring than I.

This was NEW to me(just learned tonight). IT WORKS!! If people already knew about this, I apologize for the retread. My guess is that it will work on the C32V37 as well(no guarantee though).

At the end of this post I will add a link to the OFFICIAL C27V36 THREAD here on the forum so that we may carry on th disscussion there.

Here we go, Step by Step:

1. Open up the front panel.
2. PRESS AND HOLD DOWN the MENU KEY on the front panel of the tv.
3. WHILE HOLDING DOWN THE MENU KEY ON THE FRONT OF THE TV UNDER THE FLIP DOWN PANEL, PRESS and HOLD DOWN THE MENU KEY on your SUPPLIED ZENITH remote.
4. This will ACCESS what I think is the first menu of the Zenith Service Menu. Mine looked like this exactly letter for letter, symbol for symbol:

RC-032A VER.[M] 3.10

CXA 2150 DEF
OSD-POSITION: 14
CXA21501080i
RGB W/B ADJ
2150 EX0 ADJ
2150 EX1 ADJ
2150 EX2 ADJ
YPbPr ADJ


Now, the first line; CXA 2150 ADJ was "HIGHLIGHTED" with an Orange highlight.

I am assuming this means that by accessing that line brings you into a sub menu in that line of the service menu. This is only a guess, as I did not access any of the lines.

Nor did I attempt to move the highlighted line at all.

A guess would be that the channel up/down(on the remote? or front panel? Again, I don't know) would change the highlight up or down to whatever corresponding line you want.

Then either ENTER on the remote? or the volume up/down?(again I don't know) would actually enter the sub-menu of each line.

To change the value of the specifically desired thread if you will, might be the volume up/down button(remote or front panel?).

Anyone who may know this, chime in please.

Now to save the values one may have changed, I DON'T KNOW HOW TO DO THIS.

THIS IS ALL GUESS WORK ON MY PART. I NEED MORE INFO TO VENTURE FURTHER.

Now to exit service menu:

From the menu I showed at the top, I SIMPLY HIT THE EXIT BUTTON ON THE REMOTE AND IT VANISHED.

I hit the menu key again(remote or front panel, doesn't matter) and the tv's regular menu appeared(Color Temp, Contrast, SVM, Color, Brightness, Etc...)

Any one with further info please speak up.

IT COULD GREATLY BENEFIT PEOPLE WHO HAVE OWNED THESE TV'S TO WORK OUT THE LITTLE KINKS IN THEM.

Most impressive.

Your Steelers almost got caught looking ahread yesterday! :p

I hope some folks from that huge c32v37 service menut thread hit this thread and set us straight.

[STEELERSRULE]

Q,

Your EXACTLY right about STILLERS yesterday. But a win is win, no matter how tough it is.

I am NOT sure this will WORK for the C32V37 or not.

Have you tried it on your tv?

Happy holidays buddy.

Doesn't work on my C32V37. :(

OKAY SOMEONE PLEASE...

I was checking out the service menu, and went to YPbPr adjust where it has the RGB values that I was trying to fix, and the top one says 'Y Adjust' so I pushed it and all the values for R G and B Offset went nuts and now the colors are WAAAAAAAY off. Can someone tell me the approximate values for these, even if they are not defaults, so I can work from there? Because I'm not able to do much right now...

One more thing, I picked up the RadioShack remote today, got home, and found out I don't need it... or do I? I can get in through the MENU-MENU thing, can the other remote do it 'better' somehow, like do I get more options? Because else, I dont need/want a universal remote.

THANKS PLEASE RESPOND

also, where can i get like a chart that tells me the decryption of what this all means? i know what i want done (especially fix the location of the corners), but it's all in abbreviations.

The MENU MENU trick works! On the 37! With the stock remote!

ALL OF THIS IS TRUE AND YOU CAN MOVE IT WITH THE ARROW KEYS ON THE STOCK REMOTE! YES!



A guess would be that the channel up/down(on the remote? or front panel?

No! Arrow keys like you would normal menu control.

Again, I don't know) would change the highlight up or down to whatever corresponding line you want.

Arrows do it!



Then either ENTER on the remote? or the volume up/down?(again I don't know) would actually enter the sub-menu of each line.

YES! The Middle button backs you out to the main menu. I notice when I access the service menu, it automatically flips to "Norma" EZ picture preset. I'm not sure if any of the changes I would make will actually hold.

[AndrewZorn]

got the problem fixed, but im still trying to confirm this: the OFA remote really has nothing on the zenith remote as far as service menu, right?

and can someone get me like a translation of all the stuff in the service menu, ESPECIALLY THESE TWO THINGS (if anyone knows them):
- the corner adjust / lower curvature... like the tv now is shaped kind of like the eiffel tower, straight at the top and edges, but the bottom sort of fans out, and i want to bring those corners in horizontally.
- what i have heard before called 'vertical compression'... imagine this, like a checkerboard on the screen, the squares at the top are more like squares, the ones in the middle more like wide rectanges because the 'line density' of the scanning is not uniform over the whole tv... can someone help??

AH YES, one MORE thing... I adjusted the tv last night to make the overscan pretty much perfect (I made my OWN black/white patterns, adjusted under different conditions, etc), but now when i push the 'arc' button (16:9 mode) and send it a 16:9 signal, the image is a BIT crunched. i COMPLETELY understand the concept of using all 480 lines etc etc, but before, a circle was egg-shaped on both modes, as the top and bottom were cut off, and now that that is fixed in 4:3, in 16:9, it looks like i went too far in the correction... anyone?????????

Vertical linearity will fix that checkerboard issue you described. V_LIN maybe.

After I corrected overscan, I has some issues as well. I ended up having to make adjustments to V_ASPECT and continually readjusting the size and positions of things. You will want to get an overscan image like the one here (http://www.geocities.com/r6d2_stuff/) and some test patterns to make sure you have the aspect and everything else OK. Its a pain. Of course, make sure the hardware you have is set to send a 16:9 signal.

I can't remember which settings help with your first problem, but there are a number of settings in the vicinity of the size and position settings that will help with this.

Okay, now concerning the above (which looked a lot better before the forum removed the spacing...):
Someone said to use V-ASPECT to fix an issue, but it seems to be the same as V-SIZE... here is that issue:
I adjusted the vertical size so that a circle was a real circle. Then I pushed 'arc' (16:9 mode) and the circle looked a bit ovalish. Still looks fine in 4:3. So is there a way to change how MUCH it is compressed?

Anyone that knows ANYTHING about those values, please help me fill in all the extra info... I don't know what most of it means.

Another thing is even though the picture fits the screen perfectly with about 1/2" of overscan on an all-white image (what I consider perfect), things are stretched vertically, as if the actual TV is too tall... suggestions?

My tv is shaped like:

.||||||||||
.||||||||||
.||||||||||
////////\\\\\

kind of hard to explain, but see how the bottom sort of pulls outward? Can I bring that in somehow?

[mrslacker]

The MENU-MENU trick gets me into the "Ez Adjust" service menu! What the heck?!!??! My TV is weird.

Hi Andrew,

It seems that I made the same mistake however the color balance on my C27V36 didn't change at all and I wonder why! Did you see the problem on any specific mode (SD component input, HD, etc.) or just watching regular SDTV off-air channels?

Your help is much appreciated.
