How do I access the service menu of my P2770HD? It overscans even in the screenfit position so that I'm unable to read the material at the edges of the screen.

    I've navigated enough service menus without messing with the receiver memory.
    I've already tried the solutions you suggested without success.

    The only device connected to my receiver is a Dish DTV PAL where I'm using one if its tuners to tune my receiver because the tuner in my set is not sensitive enough to get an acceptable picture. This is, of course, set to1080. My set is used only for OTA reception.

    I've tried every setting on the pic size button on my receiver remote and none give an acceptable size without cutting off some information.

    All I need is access to the service menu where I can work the horizontal and vertical sizes to eliminate the overscan. Thank you.

    Solution #2 is a crazy non solution. It had to do with microwaves NOT a television.

    Please stay on topic and give me a real solution: how to access the service menu.
    Thank you very much.

    1- I have a user manual. It does NOT contain instructions to access the service menu,

    2-
    I've just purchased this set (refurbished) for $285 to replace a Toshiba 26" CRT set
    which also overscanned and had intermittent audio dropouts as well.

    However, the picture displayed by the Samsung P2770HD while good, pales in
    comparison with the Toshiba. Moreover, the tuner in the Samsung is so insensitive
    that I was forced to drive it with one of the tuners in my Dish DTVPAL DVR to get an
    acceptable picture. To cap it all, the audio output with the VC set at max is woefully
    inadequate.

    If I refused to put up with the hassle of getting the Toshiba to a service man, I'm surely
    not going to do so with the Samsung, in addition to spending over 50% more to do so,

    Your cryptic response doesn't indicate where and how I'll find a solution in my remote.
    I've searched the remote and can find no path to accessing the service menu.
    Furthermore I'm very unhappy that Fixya is such a poor internet citizen by doubleposting
    emails to me.

    Please spare me your cookiecutter answers.

    G'bye.

Hi please find above your user manual, for download. The instructions should be in the manual, to allow access to your service manual.
I doubt that it anything in the service menu will sort your problem out however. What is happening to your set, is to do with a problem with the horz scan circuitry, most likely it is a power problem, and the scan circuitry is being overdriven by a high voltage somewhere, or indeed an IC jungle chip partial failure, this can sometimes be caused by fault electrolytic capacitors on the screens Higher voltage side.. or dirty power supplying the PLL's/Oscillators.. but as usual it also could be one of many many other "causes" that produce the same or similar symptoms..
To track down the exact problem you will have to obtain a service manual. I have searched the net, but haven't been able to find one.. You may have to contact the manufacturer or an agent of Samsung, to obtain a copy.
Otherwise it is a problem for a serviceman, a repair like this IF straight forwards shouldn't cost much more than US$150.. incl parts.. However as with ALL electronic devices, ALWAYS ask for a "Quote" for the repair before allowing any repair work to commence.

Before taking such a drastic measure as going into the service menus, which can erase the television's memory if not done correctly please make sure it is not the attached devices' fault. If you have a cable box or satellite receiver make sure that it is set to 1080i for resolution. Then find the hdzoom # or format or aspect button (is usually hd zoom #) on your cable remote. Press it until the picture is the right size. Try another device like a blu ray or dvd player and make sure zoom has not been selected on its remote control as well.

You will have the option for the same in your remote. If you don't have your remote, you can do the same on the sides or rear portion of the T.V.

1. the soda was a good choice for the smoke damage that you have experienced but
it is very difficult to remove smoke from the inside of a microwave or for that matter
and thing that has been heavily concentrated with smoke.
2. Lemon juice concentrated when applied to the walls and the floor of the oven will
curtail some of the smoke and break it down over time. It will take several coatings to
accomplish this. Lemon has a high citrus acid content and will break down the oils that
adhere to the walls of the oven. This is not a finale remedy I'm afraid. The oven is damaged
and I recommend a new one because constant cooking in this oven will induce chemicals
into your food that you prepare in it that may harm you later.
I recommend purchase of a new oven.

How do I enter the service menu on an Emerson EWF2004 CRT Television? (Pictures of the OVERSCAN ISSUE will be provided if needed.)


Older sets had vertical and horizontal size controls. If you have the horizontal size control, turning it counterclockwise will reduce the size of the picture horizontally and reduce the overscan.

Apex TV Service Mode


The service menu for this TV may be accessed by holding down the INPUT button on the TV and pressing 2580 on the remote. To navigate the service menu use the arrow keys on the remote. The center Enter button is used to go down into a submenu. The Menu button returns from a submenu. The exit key exits the menu.

There is an option to adjust Over Scan in the Picture settings menu. Set the positions to zero and the size to +100 for both horizontal and vertical. Then set the Sharpness to zero in the Picture Mode menu for each picture mode (optional, but sharpness makes text and sharp lines really ugly if you're using a PC).

I've owned this TV since Feb. 2013 and I've been disgusted with its lack of disable-able overscan and forced to use VGA to get a usable picture. The VGA port finally started going out (flickering colors) and rather than tearing it apart to resolder the VGA connector I tried to find a service manual again. Found one for a different Apex LCD TV but the service code was the same. It's like having a brand new, much better TV now! Overscan is the worst thing the TV industry ever did, it's totally and completely unnecessary on digital, pixel-perfect signals.

Panasonic video projector, via Composite video in. Horizontal Dotted white line on top of picture edge Left hand side to nearly mid way point. What's going on?


You may need to adjust your overscan.
To do this you will need to press "MENU", choose "POSITION", now adjust the "V-POSITION" and move it only until the white line disappears.
The line that you see at the top sounds like SMPTE code, which is used by broadcasters for many purposes. http://en.wikipedia.org/wiki/SMPTE_time_code

AOC monitor 2436vh does not fill the screen using the HDMI connector. There is a 1 inch black border around the window. Controls to stretch the display are locked out (not accessible) when using that...


The "Best Solution" fixes a problem that is unrelated to the original poster. anononline19's solution is to fix the entire OSD being locked (displays OSD Locked when the menu button is pressed).

Original poster's problem can be fixed by changing your graphics card's "overscan" settings.

The picture has ''zoomed'' out. can't read text on scroll bars. fuz


Please try using the zoom button on a universal remote. The button on the remote may no longer be working. Otherwise the best way is to open the set and test each capacitor and transistor with a multimeter to see which ones if any need to be replaced.

Panasonic viera doesn't display computer correctly


I have had what is fundamentally the same problem. I have a desktop PC that I am plugging in to my Panasonic Viera TX-32LZD80. I am using DVI connection plugged in to HDMI port.

The solution is fairly simple; use the Menu button on the TV remote to get to the Main Menu for the TV and then select Setup which should be the fourth of four options. This will get you to the Setup Menu for the TV for the current channel. Look for the Picture Overscan option, it will very probably be set to On if you have the problem of %5 or so of display being missing on all sides.

Switch Picture Overscan to Off.

This immediately should solve your problem. A note of warning on this is that I suspected this was the problem but when I first looked at the Setup Menu I could not find the Picture Overscan option.

If you are unable to find the Picture Overscan option then trying fiddling with the Aspect settings. You will probably find it set to Auto. Switch it to 16:9 and you should find the Picture Overscan option will be available from the Setup Menu.

Hope it works for you.

Overscan


For Factory Menu, press MENU 1 3 7 0
Service Adjustment Mode, press MENU 2 3 5 7
Convergence Mode, press MENU 2 3 5 9
Use the VIDEO or VIDEO buttons to enter two different groups of adjustments
Use the VIDEO / VIDEO buttons to toggle thru the adjustments
Use the + and - keys to adjust
When finished with adjustments, press ENTER to save
Press MENU twice to exit service mode
Hope this helps. You should look for the vertical height or size adjustment. Do not adjust anything you don't know about.

Zenith Z27X22D Service Menu Codes needed


significant vertical overscan. It is such that it's impossible to read crawls and such at the bottom of the screen. I think this problem is a tv problem. it is due to vertical section. please change electrolytic capacitor in vertical output section. it will be ok. it is common problem can be fixed at home & very simple.

Overscan is off a bit


Does's the set have a repair history? If it was previously serviced , the capacitor which is connected between the emitter and the collector of the horizontal output transistor transistor might have been changed with the wrong value, which would cause and overscan situation.The service menu for this set is even hard for technicians to use. It' my opinion if the service manual will not correct the horizontal width, the wrong capacitor was probably installed. Scrivitron (also these sets are known for the forementioned capacitor to short , flame or open.
