switching channels with program guide
I sometimes encounter a problem when I switch a channel with the program guide function on my 40plf8605. Approx 1 out of 10 times when I try to switch to a different channel directly from the program guide function the TV goes black. The TV set stays on but no channel is shown. If I redo the same action again, there is a big chance it works normally and I can view the selected channel. Upto now I've only encountered this when I switch inside the program guide menu system. Did anybody else encountered this issue?
