ADJUSTMENT PROCEDURE
[1] ADJUSTMENT PROCEDURE
1. Adjustment method after PWB and/or IC replacement due to repair
The unit is set to the optimum at the time of shipment from the factory. If any value should become improper or any adjustment is necessary due to
the part replacement, make an adjustment according to the following procedure.
1. Procure the following units in order to replace the main unit, IC3301, IC8101, IC3501, IC3502, IC8301, IC8302, IC8303, or IC8304.
NOTE: [Caution when replacing ICs in the main unit (IC1501/IC1502/IC1503/IC1505/IC2002)]
The above ICs are EEPROMs storing the EDID data of HDMI and the monitor microcomputer. Before replacing the relevant part, procure the
following parts in which the data have been rewritten.
2. After replacing the LCD panel or LCD control PWB, adjust the VCOM in the following procedure.
1) Enter the process adjustment mode.
2) Use the cursor keys 
/
 and P 
/
 of R/C to select the item [VCOM ADJ] on the page 10/14.
3) Press the OK key to verify that the adjustment pattern is displayed.
4) Use the +/- keys of VOL of R/C to adjust the flicker in the center of the screen to minimum.
5) When the optimal state is achieved in Step 4, press the OK key to turn the pattern to OFF.
2. Entering and exiting the adjustment process mode
1. Unplug the AC power cord of running TV set to force off the power.
2. While holding down the “VOL (-)” and “INPUT” keys on the set at once, plug in the AC power cord to turn on the power.
The letter “K” appears on the screen.
3. Next, hold down the “VOL (-)” and “P ( 
)” keys on the set at once.
Multiple lines of blue characters appearing on the screen indicate that the set is now in the adjustment Process mode.
If you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
4. To exit the adjustment process mode after the adjustment is done, unplug the AC power cord to force off the power. (When the power is turned off
with the remote controller, once unplug the AC power cord and plug it in again. In this case, wait 10 seconds or so before plugging.)
