Samsung TV - Most of the screen has dimmed!

<< < (2/3) > >>

Turnip:

Picture is interesting as although bright RHS and dark in the centre the LHS is slightly brighter, also the change in brightness is very gradual which wouldn't be expected with a screen issue.

As we can't know the actual brightness, just relative brightness, tend to suspect it's an odd inverter issue, as in that case, ends can be brighter than the middle, esp. if tubes are all in parallel - Chris.

Checked connections again to no avail....:(

I ve posted the below links for a better view of the fault and how the TV is designed:

In your very first picture in your original post, what are all those artifact that appear just below the centre net of the court? I'm still intrigued by this problem.

If the backlight fluoros are that bad, as some portend, the TV's protection system should extinguish them totally. I'm leaning towards a bad LCD display.

You give no indication that you've tried unhitching the 2 flat leads at the top of the T-Con, one at a time, so we can see what effect it has in each half of the screen.

as your set looks like it uses two inverter boards one left one on the right is it possible one is faulty and the one board is trying too drive all the lamps hence not fully lit.

The artifacts you are seeing are our reflections :)
