Need to tweak hidden settings on your Mitsubishi TV? The service menu gives you access to advanced options for fixing picture issues or resetting your TV. This guide provides up-to-date codes and instructions for 2025. Follow these steps carefully to avoid problems.
Note: Mitsubishi stopped making consumer TVs in 2012. These codes apply to models produced up to that year. For newer TVs from other brands, check brand-specific guides on TVServiceMenuCodes.
What is the Service Menu?
The service menu is a hidden area in Mitsubishi TVs. Technicians use it to adjust settings like picture alignment, color balance, or hardware diagnostics. You can access it too, but it’s not meant for casual users. Common uses include:
- Fixing blurry or misaligned pictures.
- Adjusting color settings for better quality.
- Resetting the TV to factory defaults.
Risks and Precautions
Accessing the service menu can be risky. Wrong changes might harm your TV or void its warranty. Follow these precautions:
- Write down original settings: Note values before changing them.
- Make small adjustments: Test changes gradually to see their effect.
- Avoid unknown options: Don’t touch settings you don’t understand.
Warning: Never select “E2RESET” in the menu. It can reset settings to random values, making fixes difficult.
How to Access the Service Menu
Mitsubishi TVs use different codes based on the model and year. Below are the most common methods to enter the service menu.
Method 1: Using Number Codes
- Turn on your TV.
- Press the {MENU} button on your remote.
- Quickly enter one of these codes:
- {0} {1} {5} {7}
- {0} {3} {5} {3}
- {0} {3} {5} {7}
- {1} {2} {5} {7}
- {1} {2} {5} {9}
- {1} {3} {7} {0}
- {2} {3} {5} {6}
- {2} {3} {5} {7}
- {2} {3} {5} {8}
- {2} {3} {5} {9}
- {2} {4} {5} {7}
- {8} {2} {5} {7}
If the code works, the service menu will appear. If not, try the next code.
Method 2: VIDEO and AUDIO Buttons
- Press the {VIDEO} and {AUDIO} buttons on your remote at the same time.
- Hold for a few seconds until the service menu appears.
Method 3: Model-Specific Codes
Some models, like the Mitsubishi CT21M5E, use unique methods:
- Press switch 701 on the TV motherboard and the {9} button on the remote for 6 seconds.
If these methods fail, check your TV’s manual or search for model-specific codes online.

Common Adjustments
The service menu offers several options, depending on your TV model. Here are some common ones:
| Adjustment | Purpose |
|---|---|
| Convergence | Aligns red, green, and blue colors for a sharp picture (common in projection TVs). |
| Geometry | Fixes picture shape issues like stretching or tilting. |
| Picture Settings | Fine-tunes brightness, contrast, and color beyond regular menu options. |
| Reset Options | Restores factory settings (use “Initialize” instead of “E2RESET”). |
| Diagnostic Tools | Tests hardware to find issues like faulty components. |
Convergence Adjustment
Convergence fixes color misalignment, especially in older projection TVs. You’ll see a grid or crosshair to adjust red, green, and blue lines. Move them until they overlap perfectly. Be patient, as this can take time.
Geometry Settings
Geometry options correct picture distortions. For example, you can fix a tilted display or adjust horizontal and vertical positioning. This is useful for DLP or CRT models.
Picture Settings
The service menu offers precise control over brightness, contrast, and color. You can also adjust color temperature for better visuals in different lighting.
Exiting the Service Menu
To leave the service menu:
- Press {ENTER} to save any changes.
- Press {MENU} twice to exit.
If you don’t save, changes may not apply. If the TV doesn’t respond, turn it off and on again.
