Good evening,
I have the same problems of vertical strips at fast image on a light background or color uniform (football matches, rugby, skiing ...).
I contacted the technical department of Philips, which tells me that this is not a problem, just that I do not settle my TV!
I expect a response engineers next Tuesday ... if no solution is brought to me, the TV in its carton and return to the store!
I am convinced that Philips is aware of the problem but can not find a suitable solution ...
A firmware update will solve the problem can be ... but here I would have changed the model and maybe even (probably) brand!
