bought a Beomaster 4500 with COde error

[carolpa]

I bought a “broken” Beomaster 4500 cheap. After plugging the BM4500 to the mains, it displayed the COde error.
After the “1 2 7 1 trick” the BM4500 seems to work normal.

Will a new battery solve this problem completely?

What are the experiences? Please advice
