The problem with this C21 -RM25. Hands when it was found not to have kept, wiped different firmware . Now both hands does not go for some reason . Blinks four times , there are no settings.
The problem solved in this way : in the service menu, set all on the menu , with options 200 , 201 , 202 do not give change , and the value is not required to deliver. TV blinks four times again , no configuration . Rewrite the memory buffer , and then as written
on the Internet:
firmware changed at 1Fc to 00. Stops blinking , there was setting .
Additionally the service menu has changed position 313 from 01 to 00.
This suit almost Poplavnoi volume control .
Do not know how people got to the bottom of this before , but it worked for a hundred %. Then, however , when it took a bit of geometry adjust , but it's okay .
