All Euro-2 chassis televisions with vertical jitter after changing IC601 The original digital video-processor IC601 has been discontinued by the supplier, so we now supply a kit part number TZS9EK002-2, which includes an EEPROM with the neccessary software changes to use a VDP3108APPA1 digital video processor without experiencing vertical jitter. Some original Euro-2 sets having the suffix M will already have this processor fitted and so do not require the re-written EEPROM. Sets affected are TX21MD1, TX21AD2, TX25MD1, TX28LD1, TX25AD1, TX25AD1DP, TX29AD1, & TX29AD1DP

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.
