1. 10. Electrical convergence adjustment ( for
PT-VZ585N/VZ580)
This is a function to correct a convergence by a pixel unit every
R/G/B ingredient.
Each pixel can be shifted in 1 dot and 2 dots maximum from right to
left and up and down.
1. Project cross-hatch pattern, confirm a position gap of R/G/B.
2. Enter the service mode (EXTRA OPTION) and select [RGB

1. 11. Ghost feedback calibration ( for PT-
VZ585N/VZ580)
This ghost feedback (GCFB) function operates to control the ghost
to be the best position constantly by detecting the aging fluctuation
of GCFB pulse generated from LCD panels. Projector reads out the
pulse status at the production and memorizes it as initial value.
* This calibration should be done when the optical block is replaced.
When the [A]-P.C board is replaced, the item "1.3. Adjusted data
