STAND-BY power supply check
- Connect the digital voltmeter between C924 and GND;
- Press power key on remote unit to make sure the TV is on standby mode;
- The read-out on the digital voltmeter must be 8.0~10VDC
Adjustment for RF AGC:
- Receive RF signal (62±3dBµV).
- Press factory key to enter Geometry Adjust MENU.
- Press “1” keys on the remote handset and on-screen display will be shown as following:
AGC Geometry Adjust
XX 100i
- Press volume "+" or "-" on the remote handset to change the value of RF AGC until snow noise on the screen just disappears.
- Press “FACTORY ” key to exit.
