REMOTE CONVERTION VATS REMOTE

HYUNDAI CTV using chroma TDA9370PS/N3/A/1931
                            But due to some region i cant able get it in market
Now I use place of this ic  TDA9370PS/N3/A/1932
There is a new problem remote not working
Then I check sansui remote is working
But how to satisfied to costumer
and rework this hyundai remote

Then here is prosedure

now sansui remote is working
so press in sansui remote    menu-0203

the topic is if in a hyundai tv set hyundai remote not working but sansui remote working
These are the solution of this fault.
If this article is help full then comment on box......
thanks.........
