Hi,

Please verify the model number of your TV so as to not get incorrect information.

Do you get still get audio when the screen dims?

Have you tried different inputs, input types e.g. HDMI, Component video, Composite video, co-ax, or even different signal sources e.g a dvd player to see if it works OK?

What have you tried?

Hi,

Here’s a composite image of the No video- Normal Audio troubleshooting procedure, taken from the TV service manual that shows what and where to test.

The manual is awkward to use online as you have to enter the page number in the box below the document and click Go every time that you want to change a page. To download it though, you need to sign up to the website.

Block Image

(click on the magnifying glass in the image and then when it opens in a new page click on the image again to enlarge for better viewing)

Apologies for the small image. I’ve typed the relevant page numbers in “red” (p.90, 92 & 110) on each of the pages in the image, so it may be easier to go directly to the page in the manual by entering the page number in the box below the document box.

Hopefully a start.
