Hello
I have a Samsung TV model PS50C7000YW in which after replacing the damaged main board BN44-00333A, the following message appears:
"Main Board has been changed.Please go into service mode and setup belowoptions.-Type, Local Set, Front Color Option"
I have to enter the service menu with the combination of buttons: INFO / MENU / MUTE / POWER but I do not know what to set.
After entering the service menu, Option displays:
Type-NONE
Local Set-NONE
Model-UC7700
TUNER-SEC-TC
DDR
Country ...
Front Color-NONE

The Factory Reset Factory does not change :(

I am asking my colleagues for help.

Could an emergency solution to the problem be to solder SMD ICQ802 PIC16F882 from a damaged BN44-00333A board?
Please confirm

In service mode I was able to set:
Type - 50FAmV4D
Local Set- NONE (field not active)
Model - UC7700 (field not active)
Tuner - SEC-TCS
DDR
Country ...(field not active)
Front Color W-Violet

But after turning on, the following message:
"Main Board has been changed.Please go into service mode and setup belowoptions.
-Type, Local Set, Front Color Option"

Probably because the Local Set option on the EU is not set.
Please help :(

TV repaired.
Samsung's service remote control helped 100%.
The black band is the wine of the tapes that connect the matrix.
Washing the tapes with Isopropyl Alcohol solved the problem.

This is a little discouraging to create a topic in this forum.
