- 1). Write down the model number and any identifying designation that you can see on the product's cabinetry, case or packaging. For example, on an Insignia television, look for model identifiers like "Insignia 19-inch Class / 720p / 60Hz / LCD HDTV Model NS-L19W2Q-10A" or similar.
- 2). Visit the Insignia website and click on the "Support & Service" tab below the leader board. Look for the text box labeled "Find more details about my product" and enter the model number or any keywords derived from the information you gathered in the previous step.
- 3). Click on the resulting hyperlink to the user manual in the language of your choice that will be on-screen. An Adobe Acrobat PDF version of the Insignia product's instruction manual will download and display. Scroll through the document until you get to the "Troubleshooting" section which is usually at the back. Follow the product-specific troubleshooting guide.
