Page 17: Adjustment Procedure
LC-26GA3E ADJUSTMENT PROCEDURE The adjustment values are set to the optimum conditions at the factory before shipping. If a value should become improper or an adjustment is required due to part replacement, make an adjustment according to the following procedure.
Page 18 LC-26GA3E Preparations To upgrade the main software, it is necessary to get ready the SD card for version upgrade before you start. Follow the steps below and create the SD card for version upgrade. 1 Insert the SD card into the SD card reader/writer. Start the SD card formatting software. Click [Format].
Page 19 LC-26GA3E How to upgrade the software 1 Pull out the AC cord to turn off the TV. 2 Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the right side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the right- hand side.
Page 20 LC-26GA3E 7 SPut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade. 8 Now the software version upgrade is complete. Note: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the main software version information.
