I searched web, but can not find service manual for this one. I selected some bad TV type in service menu and charset is now broken. I don't have the courage for trying blind, i have read service manual for B series and there is Hz rates and backlight and some other shits that I believe could damage/broke/brick my TV, when I select badly. And because warranty is over, I want to get proper setting from service manual.
Language must be Czech, I have EPG with bad charset.
Thanks for help.
