SYMPTOM Zoom mode does not work correctly.
CAUSE
Software corruption.
ACTION
If the VDP has been replaced, ensure that the correct version of software is fitted (H3-
02x00).  It is also necessary to ensure that the NVM is blank, so that new data can be
written to it when the new software is fitted.  To ensure that this process is complete,
change both the EPROM and NVM together.
If problems still occur, it will be necessary to adjust the picture, while in the zoom
mode.  This can only be carried out using a dedicated remote control.  Please contact
Sharp Technical Support in this situation.
