Voltage as follows:
Between T+ & T- reading various between 0 to 24v
Between B+ & B- reading various between 0 to 60v
These are strange readings I think it should not change?Leave a comment:

No light at all, although I can see the picture when I am using torch light from top or corner of screen
Also I noticed from the previous reading that pin7 is reading 280v while it's return on the board as N.C not sure if this will help us in any direction?Leave a comment:

I replaced my multimeter battery today, before start checking
Is there anyway to check if there is an open circuit LED? Is it possible to know from the connector itself?Leave a comment:

Samsung LED TV UN55C7000WFXZA no backlight sound is ok
Hello all,
I am seeking your help diagnose my TV Samsung model UN55C7000WFXZA, the picture and sound working fine but without the backlight, I discounted the cable between main board and power supply the backlight didn't come!
I think the problem is with power supply board, I searched in the database looking for PS diagram model BN44-0376A I couldn't find it.
I am posting few pictures here to let you know the boards and appropriate your advise and help
Thank you... -
