Adjustment Instructions - LG 60PY2D-AB Service Manual

1. Application Object
These instructions are applied to all of the PDP TV, DF-057B.
2. Notes
(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test equipment.
(2) Adjustments must be done in the correct order.
(3) The adjustments must be performed in the circumstance of
25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.
(4) The input voltage of the receiver be must kept 220V, 60Hz
when adjusting.
(5) The receiver must be operational for about 15 minutes
prior to the adjustments.
O After receiving 100% white pattern, the receiver must be
operate prior to adjustment.(Or white condition in HEAT-
RUN mode)
O
Enter into HEAT-RUN MODE
- Press the POWER ON KEY on R/C for adjustment.
OSD display and screen display 100% full WHITE
PATTERN.
[ Set is activated HEAT-RUN without signal generator in
this mode.
If you turn on a still screen more than 20 minutes (Especially
Digital pattern, Cross Hatch Pattern), an afterimage may occur
in the black level part of the screen.
Each PCB Assy must be checked by Check JIG Set before
assembly. (Especially, be careful Power PCB Assy which can
cause Damage to the PDP Module.)

(2) Va Adjustment
1) After receiving 100% Full White Pattern by Video/RGB
or selecting White Mode of Heat-Run Mode, Execute
HEAT RUN over 10 minutes.
2) Connect + terminal of D.M.M to Va pin of P805, and
connect - terminal to GND pin of P805.
3) After turning RV501, voltage of D.M.M adjustment as
same as Va voltage which on label of panel right/top.
(Deviation; ±0.5V)
(3) Vs Adjustment
1) Connect + terminal of D.M.M to Vs pin of P805, connect
– terminal to GND pin of P805.
2) After turning RV401, voltage of D.M.M adjustment as
same as Va voltage which on label of panel right/top.
(Deviation; ±0.5V)
