PhilipsFL1.16Wrong service batch of ST24C08CB1 memory IC'sWrong service batch of ST24C08CB1 memory IC's 4822 209 32283 ------------------------------------------------------------ Temporarily a wrong batch of EAROM's has been delivered, causing the fault "NVM MEMORY NOT WRITE PROTECTED" after replacing the EAROM
PhilipsFL1.16Various faults can be observed.Check the earth connection from the SSP: connect earth tuner with earth line output transformer (LSP) to find-out whether the problem is solved. Check connectors L02 and S02 pins 1,2 (sometimes only 7 wires are used in the connector)



Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
