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?

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

This sounds like a common problem on these TVs (it's happened to both of my AOC TVs a couple times). Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

I have a HL-P6163W, hooked to dish network hd


Fire the TV Tech! Your problem is the adjustment to the color wheel timing. To correct this: With TV OFF -> on remote, press MUTE, 1, 8, 2, POWER. The TV will come up in service mode: ( Left / Right arrow keys for item selection, Up / Down to change values, Menu to return to previous menu, Power to exit Service Mode)

Enter the submenu of item 1. DDP1011. Now, adjust item 4. INDEX DELAY to correct the "clay facing" problem you are having . Default value is 47.

You should have a "problem" image paused to check you work if possible. I hope this was of some assistance, best wishes.

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)

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?

RCA P52921 Color/Alignment Grid


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
