Hi Al,
So far you have eliminated the main board and probably the LED backlights from being the cause of the problem. Just leaves the IP board. Have you monitored voltages such as INV-ON (=BL-ON), PWM and ERR. May give a clue. Bruce

As you can see in the index there are more than 88 pages only for led tv
someone reduced the whole to 26 pages!The most is missing!!
Hope that someone can upload complete!

Not my doing, Thoma. I merely attached what I have, but if you're keen, I've uploaded UE50F6400 service manual to Uploads/My Files. Different model number,
I know, but may be reasonably similar. Bruce

Many thanks for all info got back to check voltages today 13v rail is gone low only 7.5 v and backlights are off now, looks like power supply is the problem,have gone round checking components but no joy,might chance ordering a panel ,
