Re: OMG SAMSUNG UN55F9000 Ultra HD, SMART, 3D 4K

i have a ue55hu8500 with cyclic problem. with one connect connected you can hear the relay attacking and disconnecting, if you disconnect one connect the display lights up and the box connection icon appears. in box one connect I replaced gl852g because it was overheating and it was short but it did not solve the problem. the gl852g is for the operation of the usb ports. do you have a suggestion i can't find repair schemes or service manuals for this tv. I think all the tensions are present and I connect 12v on the one connect power...
