| Panasonic | Euro 2 | 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 | ||
