I'm having alignement issues with my big screen. I know there is a way to get to the green grid screen, but I can't remember how I did it before. It has something to do with pressing the menu and power button, and then pressing the volume up? Then you would get P and V values... sound familiar to anyone?
The problem I am having is that when you go to the convergence menu, the green centering menu is too big width wise, extends beyond the viewable area.. also seems like the pin might be off just a little.
I am having the same problem. Just came across this information on another website.
Hope it helps. (Both of us)....

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.
Having sound issues, just unplug your TV for 10 minutes and it will reset itself...almost like rebooting a computer. I was so ticked as my sound just went out yesterday during the buckeye game, but the picture was perfect. Found this issue is a common topic on several forums. Just try it and save some money. One more note, there is speculation that the Spike TV channel causes the failure. I'm not an expert, but something to due with signal overload? Good luck!

The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board is dead.The tv convergence board must have replace the 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.
The grid (called an overlay) is put in place to fine-tune one of the colors, usually green. Once one color is adjusted perfectly, the other 2 colors are adjusted to match the first color. For example, if the convergence data is completely erased, the tech will set up the overlay and align the green using to the overlay, and then align the red to the green and then the blue to the green. If the alignment is being done after replacing the convergence IC's because one or 2 colors are slightly off in the corners, the green is usually very close to perfect and the use of the overlay is not absolutely necessary. It is pretty easy to align one color using the outer edges of the screen itself. If you do need the overlay it can be purchased from any Hitachi parts distributor such as Herman Panson, Fox or Union Electronics.
First, this assumes nothing else is going on to cause it. Here's what I did. Go to the 'green grid' via the v76 menu and go through the alignment there. Notice that there are red letters, blue letters, and a green grid. While you are in this screen, adjust the red, green, and blue focus watching the individual color's item until they are in focus. If they won't focus here, they won't focus and you have something else wrong (what I do not know). Then, return to normal programming, then select menu on the remote, then screen, then adjust projection tv convergence both horizontal and vertical crosshare. That ought to get it.
They are definitely a part of the convergence circuits. A variable resistor increases resistance as they warm up. So excessive heat destroys their capacity to perform as was designed and you will continue to have issues until all components are within 5% tolerance levels. Hope this helps. let me know if you need anything more for information.
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
Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
