Thanks Suranga,
I have a monitor with a similar fault and although we shouldn't guess, I feel pretty confident that I will find faulty caps.

Thanks for the tip. Is there a chart or table that gives the DC voltage for different sizes of LED screen size?
Thanks.

Very useful information on checking the backlight voltage level that highly depends on the size of the TV screen.
