With power on, press Mute-1-8-3. That will get you into convergence mode. 1 sets factory default convergence. Avoid pressing 2 - it resets everything. 3 restores the last saved settings, 4 switches among fine adjust, line adjust and grid move. 7,8,9 - select R,G,B. The three keys below those turn RBG on/off.

Self-focus to save the settings. S-Mode to exit.

It can be a REAL headache, but take your time, and you'll get it done.

As an after thought....if you have a need to manually adjust the convergence, you probably have something wrong - unless you've just replaced parts and are doing the initial convergence.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

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.

Convergence


Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.

Convergence


If the convergence adjustment is not moving the beam chances are the convergence IC(s) are defective. If you know how to solder and understand TV safety you may be able to fix it. With power disconnected remove the back. You should see two large heat sinks with large ICs (3 by 6 inches) with about 30 leads going through the circuit board. Numbers on the ICs should usually be something like STKxxx-xxx or some variation with x being a number. These ICs control the position of the three beams. If they go bad you can't adjust one or more beams. Replace them both as you don't want to get in there again in 3 months. Cost is not that much. http://www.tritronicsinc.com or http://www.partstore.com should have them at a reasonable price. Before replaceing the ICs look at the circuit board closly for cracked solder joints. Resoldering any bad joints might just solve your problems and avoid replacing the ICs. Good luck and remember safety.
