Hi ! 

I received a Beocenter 8000 from a friend that worked fine and then stopped working (no red dot when i plug it, no responding command no "clic" sound BUT the CD laser head is initializing... ) So i guess the problem is from EEPROM (someone told me it could be the point) so i'm looking for help to replace the EEPROM but i need to know more about it. I know that EEPROM is a memory that erase when you plug out the mains. But i know that there is a program inside the EEPROM... So is it working with a battery ? If i replace the EEPROM do i have to replace a battery too? 

Thanks for your lights about it !

Check the power supply.
Check for cracked solder joints at the large filter capacitors and at the relay.

Hi thank you for your help ... My technical English is very poor as a French guy ... So could you be more precise about the parts I have to check ? Maybe if you can send me a picture or a technical drawing about the parts to check that really would help me !! :-) thank you very much !!

Vérifiez l'alimentation principale (avec un voltmètre…)

Vérifiez les soudures au niveau des gros condensateurs et du relais, Elles ne doivent pas être craquelées ou "sèche".
