Hi,
I'm trying to find access to service menu and had tried following:
1) TV is off, press i+, 5, vol+ and switch on with remote
2) press the ´i+´, ´5´ and ´VOLUME -´ buttons all three together for 5 seconds. Then the INPUT button
3) One remote press one button after the next 'i+', '5', 'Analog'.
4) TV is on, left,right,mute,center button,mute,menu
but nothing works

I hoped 26L4000 would be close to 32L4000. My remote is RM-ED014.
For sure, does "center" mean the round button in the center of left, right, up, down arrows? In my case TV responds to pressing this keys like I would press it individually. Does it depend on current signal source?
