hi,

i have bad news for you. For strange reasons we have had three TV bricks on russan forum until today. All bricks were after execution reboot command in console. One brick was because of channel editor over web ui. We didn`t have any help, ExLink cable didn`t solve this problem. And why reboot kills TV we do not know yet. I`m sorry :(

So to do not waste your time i would recommend you bring it to Service.

I add warning to do not use reboot function, it is to remove in next version of hack (it is coming...)
On many tested TVs everything works perfect, but on some - especially C5000QW (TDT), two TV C550 (TDT and MSX) - not.
Log we saw on those bricked:

They are changing mainboard by warranty. You do not need to know part number etc.
Looking at the log I guess it's quite easy for the service guys to find out what "happened" to the TV
No, from log here isn`t any hint about hacked tv. Guys from Service might have other methods to know what happened, but not from this log. ctyhack is normal process and it is not related with hack.
so it wouldn't really make sense to invent long stories...
Why not? :)
Mainboard have being changed in such cases ussualy. Good luck!
