How to enter service mode to resize grid.

When the TV is on the picture is larger then the screen. Had a tech over several years ago and he went into a setup mode where a grid appeared and he was able to change the size of the picture. Can anyone tell me how to get the TV into that grid mode so I can resize the picture?

Re: How to enter service mode to resize grid.

Many a good set have been destroyed by stumbling around in the service menu. One wrong thing and boom no more Tv. But we'll try to help you here, turn the set off. hold both the volume down and chanel down on the front of the set. hold them both in till the set turns on Then from this menu go to geomatry and you should be able to adjust from there , and for Gods sakes write down the values before you change them so you have a refrance point should things go terribly wrong

There is a wave/bow in the bottom and top of the picture on the screen of my Toshiba 70HX50. When I am in the grid screen in the service mode, it looks like the center is 'bowed' out. How do I adjust this...

Slight error in the alignment of a projection TV is pretty much normal. If the problem cannot be seen on a normal TV picture, I would not spend the money.
However, if the problem is severe and causes colour double images, it is convergence and will need parts replaced - about $200-$600 depending on service call, parts, labour, etc.
Minor adjustment takes a skilled technician. attempting it yourself will likely cause the set to stop functioning. (Digital adjustment is not forgiving)

Heres how you get into the service menu. BUT be very careful write down anything that you change as this can screw your set up and if you write down everything you will be able to change it back if it affects your set. You may want to consider getting the service manual which will explain all the details on the convergence adjustments. If so let me know and I will post a link where you can get one along with free tech support to help you out with it.
Put the TV in Standby Mode.
  • Then press the following buttons on the remote:

    {DISPLAY} {5} {VOL+} {POWER}
    {DISPLAY} {5} {POWER}

  • The TV will turn on with the Service Menu displayed.

  • Use numbers {1} and {4} to select the item to adjust.
  • Use numbers {3} and {6} to adjust the value of the data.
  • Press {MUTE} then {ENTER} to save new settings.
  • The words "WRITE" in red will show up in the upper right corner if saved.
  • Turn the TV off to exit the service menu.

    Yes, you have a size problem you have horizontal and vertical size. Either its' in the service mode or somewhere on the set, with this set it's probably in menu. Must be set too high. I will look for menu codes! Is this an Akai or Panasonic set?

    What your looking for is called the service menu. This is not an adjustment you should attempt unless you first read the service manual as the wrong button pressed while in this menu will cause permanent damage and an expensive repair. My best suggestion is for you to call in an authorized RCA repair person to do this for you, or purchase a service manual before you attempt this alignment procedure. Good Luck

    RCA P46921 alignment issues

    I am having the same problem. Just came across this information on another website. Hope it helps. (Both of us).... 5.4 GE / RCA / PROSCAN Read the _ SERVICE MODE WARNING _ before proceeding. To enter service mode, push and hold the [Menu] button on the set. While holding, push and release the [Power] button, then the [Vol +] button. You will now have some information on the screen: "P0 V0" To actually be able to change these values, you must push [Vol +] on the remote so the information reads V76. Then pushing on the Channel +/- will change the "P" value. P1 - 3 are error codes. If there is a problem with the set that can be self-diagnosed, the "V" will report the code. These codes are available in the RCA repair manual. P4 - 7 control the horizontal size, shift, vertical size and shift. You may also find a summary leaflet for the service tech clipped somewhere inside the chassis. The procedures for getting into the service mode, as well as the service items of interest will be there. If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.

    Red convergence is out of alignment

    If the mis-convergence is only noticable on the left center and the top and bottom left side of the screen is good, then it sounds more like a pincushion distortion problem rather than a convergence one. Otherwise, you could have a bad pair of convergence IC's or capacitors / solder connection problems. I would doubt that adjusting the service menu would correct this problem, and you could make it much worse by trying. Better have a technican work on it if the picture quality is still good otherwise.
