BenQ monitors repair
Book a technicianDescribe the BenQ TVs problem
Describe the problem by source: does the built-in menu appear, and is one input or even the menu affected? This distinguishes source-related issues from conditions requiring TV inspection.
For BenQ, record the model, input and video source. Built-in speakers and automatic input switching depend on the model.

Symptoms and inspection notes2
Sound present but no picture
Note menu response and the power indicator; do not press the panel or open the back.
One input has no picture
Check source selection and external connections without using a damaged cable or changing service-menu settings.
No Signal on a BenQ monitor1
A signal-status message, not a code identifying a failed component. Follow your model’s input instructions.
| Code | Meaning | Cause |
|---|---|---|
| No Signal | No video signal available at the selected input | Check the video source, connection and correct input selection through the model’s monitor menu. |
Care according to your manual1
Screen care
Follow the manual’s cleaning method and do not spray liquid directly onto the screen or openings.
A question about the problem1
Does No Signal prove a faulty BenQ monitor?
It is a signal message, not a component diagnosis. Check input selection, connections and source according to the manual; arrange inspection if it persists.
