(6) It is possible to check how many Generations are created
at this point.
(Fig. 7) shows that you have created 130 Generations and
you will start from 131 next time.
4-3. HDCP Download Method
(1) Input power of Stand-By 5V.
(Download must be executed only when it is on Stand-by)
(2) The RS-232C(9PIN) must be connected to the COM1 on
the PC.
(3) If all the preparation is completed, click on ‘Download’.
(4) If abnormal state (Fig. 10) display then (3) execute.
5. POWER PCB Assy Voltage

(Va, Vs Voltage Adjustments)
5-1. Test Equipment :
D.M.M. 1EA
5-2. Connection Diagram for Measuring
Refer to (Fig 11).
5-3. Adjustment Method for
P/No. 3501V00180A B/D
(1) Va Adjustment
1) After receiving 100% Full White Pattern, HEAT RUN.
2) C terminal of D.M.M to Va pin of P805, connect
- terminal to GND pin of P805.
3) After turning RV501, voltage of D.M.M adjustment as
same as Va voltage which on lable of panel right/top
(Deviation; ±0.5V)
(2) Vs Adjustment
1) C 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)
