Hi!

Today the ROM V1.04 arrived. After i replaced the old ROM with the 
new one nothing happens. You just have to replace the chip, nothing 
more, right? I am sure that i inserted the chip in the right 
direction. I had the same problem with my DVD player. But there you 
had to replace resistors, also. After fixing a connection from one 
resistor to another everything worked fine. I think that the chip is 
out of order. I will send it back to yamaha and want another one. I 
just wanted to know, if you just have to replace the chip or if i 
have to do something more?
