panasonic lcd tv flicker	Can't Post

hi all
Im hoping someone can point me in the direction to fixing a flicking issue on my Panasonic TX50A300B LCD TV not sure if it the back-lights, this is a white flicker with quite a few lines i can get to the menu (hard to see but i can navigate) i have reset turned the back light all the way down,it is the same on all av's i am a competent solderer if needed and can replace the back lights but don't want to be buying loads of parts in the hope i find the real issue when im hoping someone here may know exactly what it is.
thankyou for any help

That was my next question.
How the picture looks in the beginning.

Reading from a Samsung bulletin that it could be the t-con if
"color picture problem will appear immediately or it is
getting more visible in short time.
- also it can appear from normal picture
continuously to picture problem in short time"
Seems to be temp. sensitive.
Perhaps time for a cooling spray
