5. Final Assembly adj.
* Caution : Each PCB assembly must be checked by check
JIG set. (Because power PCB Assembly damages
to PDP Module, especially be careful)
5.1. POWER Supply Unit PCB Ass'y Va/Vs
Voltage adjustment.
* Caution : Both Vs and Va voltage adjustment are necessary.
5.1.1. Model name
: PB32A

ment.
5.2. White Balance adj.
5.2.1. Overview
■ W/B adj. : Objective & How-it-works
- Objective: To reduce each Panel’s W/B deviation
- How-it-works: When R/G/B gain in the OSD is at 192,
it means the panel is at its Full Dynamic
Range. In order to prevent saturation of
Full Dynamic range and data, one of R/G/B
is fixed at 192, and the other two is lowered
to find the desired value.
5.2.2. Equipment
(1) Color Analyzer : CA-210 (NCG: CH 9 / WCG: CH12 /PDP
Module:CH10)
(2) Adj. Computer (During auto adj., RS-232C protocol is
needed)
(3) Adj. R/C
(4) Video Signal Generator MSPG-925F
720p/216Gray(Model:217, Pattern:78)
→ Only when internal pattern is not available
■ Color Analyzer Matrix should be calibrated using CS-1000
