Has anyone any information on removing the backlight panel on this model as the display is part of the frame and either the panel needs to be removed from frame or the backlight panel unclips from the rear leaving the panel on the frame . Not sure how to go about it ?Leave a comment:

Samsung QE55Q700T
Can anyone identify these diodes on the buffer board and tell me where I can get replacements , also has anyone got a service manual for this tv as can't find one anywhere.
What sequence on the remote works for the service menu ?
The tv reboots when been switched on for a while and want to check these diodes out as they seem to be a problem as I've read up on here .
Tried 4xpsu,t-con,led and mainboards and seems to stop happening when I disconnect any ribbon cable from t-con to buffer boards.
Display has no lines or defects from what I can see .
Any advice... -
