Tx48CX400b Panasonic backlights

[Maveriksam]

I know this is a popular subject but I was wondering if one of the LED's on my backlights could cause the backlights to all go out after 5-10-15mins?
The TV turns on fine, then after maybe 20mins the backlights go out. Then turning the TV off and back on again the backlights go out after a few minutes.

Each time I can turn it off then back on and they work for a few minutes and then off.

Yes. Try turning down the backlights level as low as possible to see if it will stay on longer. You also need to provide the pictures of the whole backside of the TV showing all the boards.
