How do I fix a Mitsubishi projection TV when the image is not centered?
Answer
On Mitsubishi rear-projection sets, an off-center image is often a geometry/convergence or input timing issue—not a broken screen. Start by confirming the source resolution and TV picture position/zoom settings, then use the service or convergence adjustments only if your model documents them. Avoid random internal mirror moves.
Before you start: stop right away if…
- Opening a projection TV cabinet can expose high voltage and misalign optics; leave internal mirror or CRT work to qualified service.
- Do not pay for remote “TV unlock” tools or share codes with unexpected callers.
Follow these steps
Test more than one source
Switch between antenna/cable, a streaming device, and another HDMI input if available. Note whether every source is off-center or only one device.
You should see: You know if the shift is TV-wide or tied to one box/console.
Reset picture size and position options
In the Mitsubishi picture or screen menus, set aspect/zoom to a standard mode (such as 16:9 or Normal—wording varies), and look for Horizontal/Vertical Position controls. Return any stretch or zoom modes to default.
You should see: The image moves back toward center, or position controls are unavailable on your software version.
Simplify the source output
On the connected device, choose a common output such as 1080p at 60 Hz and turn off variable refresh or 120 Hz options if present. Reconnect HDMI firmly and retest centering.
You should see: The Mitsubishi set locks to a stable full-screen image that is better centered.
Use model convergence/geometry only if documented
If the whole image remains shifted after source and menu checks, consult the model’s official service or advanced geometry/convergence procedure. Stop if the menu requires a service code you cannot verify for your exact model.
You should see: You either complete a documented alignment or determine professional service is required.

Extra tips
What to look for: Image shifted left/right or up/down, black bars uneven, warped edges, or menus that mention geometry, convergence, position, or zoom on a Mitsubishi projection TV
Before you change anything: Write down the Mitsubishi model number from the rear label. Note which device is connected (cable box, game console, antenna) and its resolution/refresh setting. Do not open the cabinet or adjust mirrors unless a service procedure for your exact model says to. Never share account passwords with unexpected callers while checking apps on the TV.
